Editor’s eye for Railtex

For three days in May, the rail industry’s showcase that is Railtex filled the 20,000 square metres of the National Exhibition Centre’s halls 3 and 3a. With over 420 stands from 22 countries, there was much to see. Indeed, it is perhaps only such trade exhibitions that show the huge variety of products and services needed to run a railway.

With so many stands, the opportunity to chat with friends and colleagues and to attend almost 70 seminars and presentations, including those run by Rail Engineer, a day at Railtex soon passes. The result is a full bag of promotional material and freebies, much learnt and sore feet. What follows is a description of the stands that caught your editor’s eye, an unashamedly arbitrary selection of exhibitors, to illustrate what I learnt and give a flavour of the show.

The large area with orange sleepered track displaying the latest rails that British Steel have to offer couldn’t fail to catch the eye. This included their Zinoco® coated rail, which provides corrosion protection in aggressive environments such as coastal areas. Although this has been around for a few years now, it is now available in longer, 216-metre lengths.

British Steel supplied the track which had a Zinoco coating.

Also difficult to miss was the large stand of Chinese rolling stock manufacturer CRRC, which is the world’s largest supplier of rail rolling stock. The stand had models of all types of rolling stock ranging from wagons to high-speed trains. I spoke to a wagon engineer who advised that CRRC had benefited from the huge increase in rail freight between China and Europe and that the company was developing a bogie that can change gauge between standard and Russian gauge. He also advised, in the UK, CRRC was to supply London Underground with 71 wagons for engineering work.

Saving carbon

A much smaller rolling stock company is Vivarail which, in 2015, took delivery of hundreds of coaches of surplus London Underground sub-surface D78 stock for conversion to affordable rolling stock on low-speed regional rail routes. On their stand, it was fascinating to talk to the company’s chairman, Adrian Shooter, who explained that the Class 230 was, essentially, a brand-new train of a modular design. The DEMU variant has two 180hp powerpack modules, whilst the motor cars of the battery variant have a 200kWh battery, giving the train a 60-mile range.

Vivarail 180hp diesel powerpack module.

Hoppeke supply both the batteries for the train and its recharging system. On their stand it was explained that Vivarail’s battery train is recharged in seven-minutes from short sections of third and fourth-rail that are only energised when the train is over them. This charging system does not need a high-current power supply as the recharging rails are fed by a bank of lead acid batteries that provide the heavy recharging current and only need a trickle-charge.

Alstom were displaying a model of their Breeze hydrogen train concept, which provides another alternative to diesel trains. This will use surplus Class 321 EMUs for a UK variant of their hydrogen-powered iLint train, which is in service in Germany. Alstom’s Mike Muldoon emphasised that these trains were only suitable for rural routes, for which discussions are being held with various interested parties. It seems likely that the UK could see a few small fleets of hydrogen trains in a few years’ time.

The most prominent exhibit on the MTU stand was their hybrid power pack. This has a 390kW diesel engine and a traction motor with a peak power of 270kW, powered from a separate battery pack. MTU have been testing hybrid drives on the continent and have achieved fuel savings of between 15 and 25 per cent. Working with Porterbrook, MTU is to trial this hybrid drive on a Class 170 DMU next year.

Turbo Power Systems (TPS) was the only stand I saw that promoted use of silicon-carbide power electronics, a recent development offering higher power density, greater conversion efficiency and less waste heat. These were being used in the compact, naturally cooled unit 13.5kW auxiliary power supply unit they had on display that TPS is developing for London Underground’s new Central line stock.

Unusual components

An unusual feature of the wheelset on display on the Lucchini Unipart Rail (LUR) stand was that one wheel was a freight wheel and the other a passenger wheel – the difference between them being that, unlike the passenger wheel, the freight wheel disc has a curved cross section which reduces track impact from the harder suspension of freight vehicles. The wheelset had a radio frequency identify (RFID) tag to easily identify individual wheelsets and their history. Its axle was also coated with a 4mm-thick Lursak impact protection coating.

From underneath to the top of a train, Wabtec’s stand featured the intelligent pantograph that has been under development for some time – indeed, it won an innovation award at the 2014 RIA innovation conference. This pantograph uses a fibre-optic cable to measure real-time wire contact force and so can monitor the overhead line equipment. It has been trialled on the high-output electrification train for a year and will be fitted to a Class 90 locomotive later this year, after which approval for general use is expected.

The various odd-shaped ducts and other components produced by 3D printing (or, to use the more accurate term, fused deposition modelling) on the Stratosys stand showed the design freedom this technique offers as well as its ability to produce lightweight components. Further evidence of its potential is that the required 3D model can be produced within a week, compared with about eight weeks for a traditional mould. I learnt that one application is producing lightweight tools for the aero industry which cause no harm if dropped.

Train Bits and More is an intriguing company name which attracted me to its stand where I learnt that the company offers train servicing including on-site toilet tanks cleaning and seat cover dry cleaning. It also offers powder-coating of internal fixtures using the highly durable Omnikote Nylon R-AG+ process.

A motorbike powered by a steam jet to accelerate it at 50 mph per second certainly attracted visitors to the IMI Precision Engineering stand. Although the bike uses some of the precision valves produced by the company, it was built by Graham Sykes performance engineering.

Samuel Taylor Ltd (STL) also make small railway components, or rather parts for components in the form of contacts used in switches and relays. They had a wide range of these tiny parts to display in this specialist engineering field. With many signalling relays still in use, it will be some time before the digital railway reduces demand for their product, especially as rail accounts for only five per cent of STL’s business.

Silver Fox also produces small electrical parts in the form of cable labels which it can produce in the form of ladders of heat shrinkable tubes that can easily be removed for fitting onto cables. It offers specialist software to prepare and print labels.

Sensors and earthworks

Both Acorel and Dilax offer rolling stock sensors to detect and count passengers. Each company offers software to analyse passenger flows for passenger counting and offered case studies explaining the benefits of monitoring passenger number and flows.

Trimble Nexala Solutions specialise in measurement, the collection of data and its analysis. For rolling stock, it uses data-processing algorithms to get effective use of data from train sensors and its automatic wayside train inspection systems that use sophisticated machine vision and non-contact measurement technologies. This provides remote diagnostic information that can be used for pre-emptive maintenance and is used by many UK train operators including South Western Railway, Eurostar, Arriva and Greater Anglia.

This information was also one of the data sets for the Data Sandbox research referred to in our “Enabling better performance” feature in this month’s magazine

Also on the Trimble stand was its GEDO Scan System, which gathers high-resolution data about track and surrounding features. It has a helical scanning mode to capture ceilings and walls to produce accurate 3D models of tunnels and overpasses. This is a productive tool for track surveys and incorporates GPS, inertial measurement and related sensor technologies. The integration of rugged hardware with customized software can compute indicative track design with continuous smooth horizontal, vertical and cant alignment. It can also create cross-section drawings, automatically detect gauge infringments and calculate OLE heights and staggers.

Battery-powered sensors to detect earthworks movement are amongst those produced by Findlay Irvine. 7,000 of their wireless tilt sensors have been installed at 180 sites on the UK network. When a site alarm is triggered, day/night cameras transmit a site image for an operator to determine what, if any, mitigation action is required. These sites are currently under trial and full approval of this system is expected soon.

US company Propex was offering its Armormax engineered earth armouring system as a way of preventing such earthworks failures. This reinforces natural vegetations and so costs less than traditional concrete and rock solutions. Although their system is widely used in the United States, this system has yet to be used on a UK railway, so the company hoped that their cost-effective, environmentally friendly solution would attract interest at Railtex.

One innovative earthworks technique that does have product approval is Concrete Canvas, which is a flexible geosynthetic cementitious composite mat which is essentially concrete on a roll and is often used for channel lining and erosion control. An 8mm concrete canvas has the same strength as 100mm of reinforced concrete. Also, one bulk roll is equivalent to the concrete supplied by two 17-tonne mixer truck.

My visit to the Lindapter stand convinced me that I was wrong to think that bolting steelwork together is simple matter. Many railway projects have the complexities of adding modern steelwork to historic structures, for which the company has developed its innovative steelwork connectors.

Of course, a lot of railway engineering work takes place at night. That used to mean at least one generator and a cluster of powerful floodlights. Now, with LEDs, batteries can be used as they are both silent and environmentally friendly.  Even hydrogen fuel-cells can be brought into play.

So it was interesting to see Peli’s area lighting systems, which now feature an ‘intelligent control’ panel. This adjusts the light output according to the length of light duration required and provides a real-time display.  Just set the hours and minutes (maximum is 24 hours – minimum 6 hours) of light required and the unit will calculate and adjust the output.

Sales manager David Smith explained it to me: “We have harnessed the new technology to develop a smarter product within the overall design of the existing unit. This real time display allows the user to plan their time and shifts accordingly.  The importance of the intelligent control system shouldn’t be underestimated as it enhances user safety and ensures jobs can be completed every time without plunging sites into darkness.”

Telent, with more than 30 years’ experience of successfully delivering and maintaining communication systems for the rail sector, is perfectly positioned to deliver the innovative digital technologies that are so important to ensure the UK’s congested rail networks run smoothly and to create smarter, more reliable services

At Railtex, Telent presented Arbitex, a remote CCTV-monitoring platform, reduces maintenance costs and increases asset reliability that is already in operation for Transport for London and is currently being implemented as part of Telent’s major stations CCTV contract with Network Rail. This solution was exhibited alongside MICA, which enhances communication, Supervisory Control and Data Acquisition (SCADA) and building management subsystems, integrating CCTV, public address systems, passenger information displays, help points, fire and intrusion detection systems and more.

TRAMMS – Telent’s end-to-end maintenance management system – enables the monitoring and measurement of fault levels and trends across a wide range of assets in many environments.

Together, the tools are at the heart of Telent’s Reliability Centred Maintenance methodology and have a proven track record in helping the UK’s rail networks increase asset reliability, reduce customer costs and improve operational efficiency.

Level crossings

ALC’s Echalon hinged column.

From bolts to hinges, the Mk III Hinge of the Aluminium Lighting Company (ALC)’s Echalon column enables it to be easily and safely lowered by one person. These columns can be up to eight metres high and, in a collaboration with SEA, are now used to carry the ROADflow signal system that detects cars that fail to comply with stop signals at level crossings. By the end of July, 88 columns with this equipment are expected to have been installed on South Eastern and Anglia routes.

Signs at level crossings and on Network Rail’s infrastructure are produced by Britain’s Bravest Manufacturing Company, which is a social enterprise of the Royal British Legion. The company is Network Rail’s only approved supplier of trackside signage. It also provides great employment opportunities for people with disabilities and injured ex-service personnel who make up 70 per cent of their workforce.

One risk at level crossings is the flange gap – a safety hazard for cyclists and wheelchair users. Strail’s veloSTRAIL eliminates this hazard. This incorporates an easily replaceable flangeway element which butts against the rail head and deforms when a wheel flange passes over it. It is approved for use for trains up to 75mph (120km/h). As it is intended for use with conventional track, it is not suitable for tram tracks.

A novel method of train detection at level crossings, displayed on the Wavetrain Systems stand, uses a complex algorithm to analyse the signal from an acoustic sensor to activate the crossing at the required time. The system is CENELEC SIL 2 certified by Lloyds Register, based on lab testing in Norway and field tests in UK, Norway, Finland, France, South Africa and Australia. It is expected to receive approval by Network Rail soon. As the system is independent of the signalling system and can be installed within 20 metres of the crossing, it offers low-cost detection. It also provides a more consistent warning time than sensors activated at a fixed distance from the crossing.

Supporting UK rail

To help rail sector suppliers understand opportunities outside the UK, the Railway Industry Association (RIA) and the Department for International Trade (DIT) jointly ran a series of pre-arranged 20-minute business focused meetings between interested companies and the DIT trade experts covering the rail sector based in British Embassies/High Commissions around the world. These covered fifteen countries including India, Kenya, Canada and the UAE.

One group of countries, the Baltic states, had its own stand. Rail Baltica is a new 870km rail line which will integrate the Baltic states with the European rail network. The project is now in its design phase and the new line, which will connect Tallinn to Warsaw, is expected to open in 2026.

Another stand that supports the industry was that of the Birmingham Centre for Railway Research and Education (BCRRE), which is the largest university-based centre for railway research and education in Europe. Their stand featured various research work, including that from its Centre of Excellence in Digital Systems, which is part of the UK Rail Research Innovation Network (UKRRIN).

During Railtex, I naturally saw much of the Rail Media stand to rest my feet, have a coffee and store promotional material from the stands. During the show my colleagues on the stand gave out 2,500 magazines – we like to think that this supports the industry by highlighting good work done and providing features about current developments.

Railtex itself also provides a valuable service by showcasing products and services, providing an opportunity for people from throughout the industry to meet face to face, make connections and do business. One good example was the Recruitment Wall, powered by Railway People, which was encouraging people to find employment in the rail industry as well as discussing job opportunites with xhibitors and visitors alike.

Of necessity, this perspective of the show is only a small part of it and omits many other worthwhile products and services. Do get in touch if you have an interesting story about an innovative product that we missed at Railtex.

Rail Engineer looks forward to seeing what’s new at Railworx in Peterborough on 11 to 13 June and at Infrarail in Olympia on 12 to 14 April next year.

Huntworth Bridge

A lift that could change the paradigm

In the depths of the Somerset farming community is a narrow thoroughfare called Huntworth Lane. It is agricultural in style, narrow and winding, but it is an important link to schools, the M5 motorway and the town of Bridgwater for the small local communities in the area.

One of the reasons why this is such an important route is because the road crosses over the main line railway from Bristol to Exeter at Huntworth. The bridge is the original structure, built in the middle of the 19th century, consisting of three wrought-iron spans with a central span of 10.5 metres and two side spans of 10 metres. It has a single carriageway and no footpath to speak of. Due to the condition of the bridge, there is also a weight restriction of 22 tonnes imposed on it.

In 2014, Network Rail put plans in place to carry out significant steelwork repairs to bring the bridge up to EU loading standards of 40 tonnes and a £500,000 contract was let to AMCO to carry out the necessary repairs. However, subsequent examinations and assessments indicated that the condition of the bridge was such that, even with the planned repairs, the bridge would still not meet the EU standard.

PM visit

Now, readers might remember the hugely disruptive floods that took place on the Somerset Levels. During that time the then Prime Minister, David Cameron, visited the area personally and promised the local community that he would invest in equipment that would increase the removal of the floodwater from the area by threefold. This would mean, of course, that new, state of the art, heavy pumping equipment would need to be imported to the area and, you know what is coming, access over Huntworth Bridge would be an essential requirement to deliver the Prime Minister’s promise.

As a consequence, a decision was taken to cancel the repair work and to reconstruct the bridge instead. An application for a 20-week road closure was submitted to Somerset County Council, although Network Rail was aware that this would not be popular with the local community as it would require a 22-mile detour.

There was another factor that had to be considered when applying for such a road closure and one that would not be easy to resolve – Somerset County Council Highways Department has a policy that no commute for school children should take longer than 40 minutes. It’s an admirable policy, one would think, but, in this case, a nightmare for the Network Rail project team. Scott Pillinger, the programme manager for the scheme, explained how this problem was resolved.

No through road!

Stranded! The bridge still stands but its approaches have gone.

Scott referred to a map of the area that highlighted a number of routes that could be taken that would ensure compliance with the 40-minute rule. However, when one looked closer, it was evident that some of the roads were privately owned by farmers and other land owners. Fairly intense negotiation had to be embarked upon, with twelve different interest groups representing the road owners.

As can be imagined, this became quite a challenge for Network Rail, given the options available to them, but, eventually, a solution was found that involved the installation of electronic gates and monitoring systems plus a reliable fleet of seven taxis to get children to school within the allotted time and without upsetting the road owners.

Network Rail representatives, including Scott, had to face a grilling from more than 300 residents who packed into a local village hall to discuss plans to close the main road to Bridgwater for 20 weeks. At one stage during the proceedings, the BBC, equipped with cameras and microphones, invited themselves into the meeting. It became a major communications initiative and regular newsletters were distributed throughout the project work.

So, once approval for the road closure was in place, the project team was then able to concentrate on the not-insignificant engineering issues that needed to be considered. Normally, a design would be developed that would enable the new bridge deck to be built alongside the track and lifted in with a high capacity road crane, but was this a feasible option in the back lanes of Somerset?

The superstructure of the new bridge was assembled on site.

Suitable access

A detailed survey of the approach roads to the bridge was carried out and it soon became evident that it would not be possible to get a suitable road mobile crane to the site and, even if it was, the available space around the site was limited with cuttings and woodland present. In fact, there was only enough space to erect a superstructure.

Therefore, the decision was made that, after demolishing the old bridge, the team would build two new abutments and then transport individual components of the newly designed steel superstructure, which would be constructed on site alongside the railway. This would then be lifted using a rail mounted Kirow crane and positioned on the abutments. Once the superstructure was in position, reinforcement would be placed and concrete poured to form the deck of the new bridge.

The design work was carried out by Crouch Waterfall and Balfour Beatty was contracted to carry out this work as the principal contractor, with a contract value of £1.5 million. The steelwork was fabricated by Centregreat at its works in Cardiff.

This all sounds sensible and normal, but a Kirow crane had never been used to carry out this kind of lift so it was a first for Network Rail. Preparatory work began on 11 February 2019, and the new deck was installed using a Kirow crane owned by Balfour Beatty on 17 March 2019, using a 52-hour possession that was in accordance with Rules of the Route.

Although this all sounds like routine practice, the benefits of adopting this approach are quite significant.

Balfour Beatty’s Kirow crane lifts the new superstructure into place.

Benefits

For example, the Kirow crane arrived on site at the beginning of the 52-hour possession. When it was ready, the crane lifted the superstructure, travelled a short distance of 35 metres, then placed the steel-framed superstructure in position. This process took 55 minutes, then the crane left the site. The only preparation required was to attach the strapping from the lifting beam to the superstructure.

The new deck is in place but access is still difficult – unless the paving-slab steps count!

Compare this with using a road-going mobile crane. First, consideration would have to be given to providing adequate road access to the site. Once on site, it is more than likely that significant ground work would have to be carried out to ensure there was a stable platform for the crane. In many cases, this would probably involve the installation of concrete bases and it is also likely that substantial areas of earth would need to be moved and transported away from site.

The crane would then need to be carefully set up, inevitably commanding a significant area of land and, because the planned lift is carried out from a distance, reliable communication channels would become necessary – and they are often complex. Once ready for work, large road mobile cranes are more exposed to weather variables, especially wind and flooding, so careful weather watching is required.

Using a rail-mounted Kirow crane dramatically reduces these concerns and risks. As a consequence, there are significant financial savings. In this instance, Scott indicated that doing such work using a Kirow crane saved the project at least £200,000 and, if all the supporting issues of bringing materials to site and removing materials from site are taken into account, the savings could be more significant.

Having said that, using a rail-mounted Kirow-style crane does require precise planning. Everything has to be ready at the right time to ensure that the crane does what is required. It then must disappear out of the possession on time, ensuring hand back to traffic is as planned, with the lift completed successfully.

Superstructure design critical

The design also has to be right. The lift carried out by the crane was 22 tonnes. A walking route was incorporated into the design to ensure that quick and safe access could be obtained as soon as the superstructure was in place. 

There must be thousands of Victorian overbridges throughout the rail network that will need to be replaced. In the past, there were standard bridge designs such as the Western Region Box Girder or the Z-type decks for underbridges. Is there a standard design emerging for rural overbridges like Huntworth and are they being designed with rail cranes in mind?

At Huntworth, at the time of writing this article, the superstructure was installed after five weeks and the reinforcement was in place ready to receive the concrete infill. The finished structure will consist of a new road carriageway, and a pedestrian walkway which did not exist before. In addition, a road safety audit raised concern about the approaches to the bridge, highlighting that there was no protection for the railway from road vehicles. So, as part of the project, the approaches, 25 metres either side of the bridge, now have restraints consisting of 12-metre deep piles with an integrated pile cap.

As Scott explained, it is a project that has included many challenges frequently associated with access but, as always, there is a unique element to each project that hasn’t been experienced before. This project, to help overcome these challenges, managed to adopt a methodology that could change the paradigm for renewing the ageing stock of Victorian overbridges for years to come.

Work starts on Horden station, County Durham

ARtist's impression of Horden station, Co Durham. (Durham County Council)

Construction of a new station at Horden, near Peterlee, County Durham, has commenced and should be complete by Spring 2020.

The £10.55 million project, which will link the area into the local, regional and national rail network and support wider regeneration in the area.

Funded by Durham County Council, aided by £4.4 million from the Department for Transport’s New Stations Fund and a grant from the North East Local Enterprise Partnership LEP, the new station is expected to bring an economic boost to east Durham.

It will feature two 100-metre platforms, with shelters connected by an accessible footbridge, as well as a 139-space car park and bus stops. The development also includes a new road, footpath and cycleway.

The original station in Hordern, on the Durham Coast line between Sunderland and Hartlepool, was closed in 1964 as part of the ‘Beeching cuts’. However, Durham County Council has wanted to reopen the station for some time as it is close to Peterlee and other towns in the south east of the county.

The new station, a little to the north of the old site, is at South East View in Horden. When it opens in Spring 2020, it will be served by one train an hour in each direction – north to Newcastle and south to Middlesbrough.

Northern Railway’s regional director for the North East, Anna Weeks, said: “We are really excited by this great opportunity on our Durham Coast route and are grateful to Durham County Council for their commitment in delivering this.

“The opening of Horden station will help connect the local community to Middlesbrough and Newcastle as well as our coastal destinations of Whitby and Saltburn and further afield to the National Rail Network.  Along with our train modernisation programme, with the removal of the pacer units in 2019 and introduction of digital trains on the line, it’s an exciting time for train users in the region.”

Commenting on the start of construction, Cllr Simon Henig, Leader of Durham County Council, said: “I am very pleased to see the start of work on a development which will bring much improved transport links for residents in the east of the county.

“The development will open up employment opportunities for local people while at the same time providing a direct connection to our coastline for visitors travelling from further afield.”

Technical Seminars at Railtex – Keynote Speeches Revised

The Technical Seminar programme, arranged and hosted by Rail Engineer, gives Railtex exhibitors the opportunity to talk about their latest developments to an enquiring and knowledgeable audience.

At the last Railtex exhibition, in 2017, over 1,000 visitors attended at least one of the seminar sessions. With the number and quality of presentations arranged for 2019, that number could well increase.

Then there will be three important industry keynote speeches. Unfortunately, Baroness Rona Fairhead resigned from the government one week before Railtex, so changes were needed.

Gordon Wakeford, the head of Siemens Mobility in the UK, will open the show and deliver a keynote speech on the first day. As well as his responsibilities with Siemens, Gordon is also co-chair of the Rail Supply Group and as such, working with a team that included Philip Hoare of Atkins and Anna Delvecchio of Amey (who will also be part of the show’s opening ceremony), he was instrumental in developing the Rail Sector Deal.

This joint initiative between the rail industry and government, including the Departments for Transport, Business and International Trade, aims to transform the rail sector by taking actions to increase the use of digital technology, boost productivity, improve the service received by those who use the railways and build the skills of the UK workforce to capitalise on these opportunities.

Network Rail chief executive Andrew Haines has recently announced that he will be moving the company further into devolution, pushing most responsibilities out to five regions and 13 routes. One of the areas affected will be the Group Digital Railway initiative, which will become much more decentralised. The man responsible for overseeing that is new Digital Railway managing director Stuart Calvert, and he will be speaking on the third day of the show.

Andy McDonald is not only MP for Middlesbrough, he is also Shadow Secretary of State for Transport.  He will close the three-day seminar programme, speaking on Labour’s plans for rail – a most-interesting way to end the UK’s major rail industry show.

Evolution not revolution

Metal wheels on metal rails have, for almost 200 years, provided energy-efficient transport due to their low rolling resistance and effective load bearing.

That apart, today’s railways bear little resemblance to early examples such as the Stockton and Darlington railway, opened in 1825. They have evolved by numerous incremental innovations, interspersed with occasional radical changes such as replacing steam with diesel and electric traction.

One reason for this is that the railway is a system with increasingly complex interfaces. Parts of it are also at capacity. These issues increase the risk from any changes, as was sadly shown by last May’s timetable changes. However, Britain’s railways must innovate to meet the 21st-century challenges of service reliability, reducing lifecycle costs, increasing capacity and decarbonisation. Generally, this is best achieved through continuous improvement rather than by radical innovation.

Yet disruptive technologies from outside the industry, such as wind power, drones, smartphones and tablets, are making a big difference. The huge expansion of wind power has reduced electric traction’s carbon footprint by a fifth over the past ten years and is predicted to give annual savings of hundreds of thousands of tonnes of carbon.

Numerous instances of smartphones and tablets, with appropriate apps, are supporting maintenance staff, drivers and many others on the railway. This includes passengers, whose apps use open railway operations data. In a news feature, we report on the RSSB data sandbox competition which aims to use this data to reduce delays.

In his feature on a trial of various new surveying methods, Graeme Bickerdike explains how drones are one of several innovative techniques that give high accuracy with minimal, if any, track access. The problem is, what to do with all the data they produce? One answer is the recently-completed ORBIS programme. We describe how, when it started in 2011, asset information was kept in diverse, ‘flat’ databases with limited information. Now ORBIS provides an overarching, geospatial view of the railway which has fundamentally changed the way Network Rail’s teams work.

Interconnected complex data like ORBIS is a feature of the fourth industrial revolution. Our article on the Railway Industry Association (RIA)’s innovation conference shows the exponential growth of internet data, which is now 1.1 zettabytes (one with 24 zeros). As our feature describes, RIA’s event featured innovations both within and outside the rail industry, as well as the support for innovation available from UKRRIN and Network Rail’s R&D programme.

Capturing and communicating the ever-increasing amounts of data on the railway will require a trackside ‘Internet of Things’, for which Network Rail Telecom is developing a strategy, as Paul Darlington describes. This will provide universal rail-corridor connectivity for an ecosystem of numerous things, including low cost, battery-powered intelligent data sensors.

One such thing is a 21st -century version of the single-line line token machine, originally devised by Edward Tyler in 1874. Clive Kessell describes how, instead of a landline to connect machines at each end of the single-line section, this uses secure IP (Internet Protocol) communication, either over the internet or a non-dedicated telecommunications link. It is a good example of Victorian engineering evolving into the 21st century.

The RIA conference also highlighted the lack of productivity in the construction industry which should be set to change. One company aims to reduce its workforce time on site by 25 per cent by 2025 by using 4D planning, artificial intelligence (AI) and industrialised construction.

Another example of construction innovation is the robots used to spray shotcrete, described by Colin Carr in his feature on the challenges of repairing Whiteball tunnel. In another civil engineering feature, Bob Wright describes the innovative techniques used to jack pre-cast boxes through an embankment to form new underpasses at White Hart Lane station.

Dr Francis Paonessa was managing director of Network Rail’s Infrastructure Projects for five years and has now left the company as projects devolve to the new regions. In a wide-ranging interview with Nigel Wordsworth, Francis describes how many did not foresee how Network Rail’s reclassification to a government body would reduce project funding. He also explains that many projects were over-spent as they were costed in too early in the project.

Yet this does not explain the threefold cost overun of the GW electrification scheme which was due to the basic design and delivery errors described in a recent RIA report. Francis considers that “there is nothing in electrification that is difficult in itself”, yet surely the lesson is that successful electrification requires skilled designers and project teams who understand its complexity. Maintenance of these skills requires a rolling electrification programme.

Effective rail project delivery requires the modern, specialist plant that will be exhibited at Railworx on 11-13 June. As we describe, this includes an InnovationWorx zone to show off the latest developments. For another exhibition report, Rail Engineer went to SIFER, the French equivalent of Railtex, where various UK companies had their latest developments on show.

This month’s magazine features just some of the many rail industry innovations. Whilst most of these will not be apparent to rail users, they form part of the continuous improvement needed if the railway is to meet the challenges of its third century.

French rail industry on show at SIFER 2019

Almost unnoticed by most of the UK railway supply chain, the 11th SIFER exhibition took place in Lille on 26-28 March 2019. The French sister show of the UK’s Railtex, SIFER has been organised by Mack Brooks Exhibitions for the last 20 years. The leading French event for rail industry professionals to meet, discover innovations and develop business opportunities, SIFER 2019 attracted 443 exhibitors, of which some 26 per cent were international, as well as 5,400 visitors.

It’s a shame that more UK companies didn’t make the trip. Lille is easy to reach by Eurostar from St Pancras and then a short walk from Lille Europe station to the Lille Grand Palais Exhibition Centre, SIFER’s regular venue.

UK exhibitors

That’s not to say there wasn’t a UK presence. Arriving at 11:27 on the 08:55 Eurostar from St Pancras, left just five hours to walk past all 443 exhibitors – and even stop to talk with a few!

Rosehill Rail.

One of the most hospitable was Rosehill Rail, which had a large stand at the front of the show. Group managing director Andrew Celik and marketing manager Daniel Fletcher had time for a coffee and a chat about anti-trespass panels and security barriers, as well as level crossing installations. The stand at SIFER, and the one at InnoTrans in Berlin last September, show how important the export market is to this very British firm from Sowerby Bridge (that’s near Halifax).

Together with French partner CH2M Rail, Rosehill was showcasing its unique Baseplated System and its latest product, the Link Crossing System. Both systems are specifically designed to be quick and simple to install in order to minimise disruption and reduce costs.

AEI Cables also had a large stand. The company serves key markets in the UK and worldwide including construction, industrial, fire protection, defence, mining and rail. Sections of cable were on display, and AEI’s experts stressed that its products meet the highest industry standards including ISO 9001 and are approved by the leading approvals organisations nationally and internationally including BASEC, LPCB and Lloyds.

Camlin Rail’s Pantobot 3D three-dimensional automatic pantograph monitoring system is a fully automated three-dimensional pantograph inspection system that allows the network operator to make real-time decisions based on true pantograph condition. This is crucial as a damaged pantograph, suffering from such anomalies as excess chipping, increased carbon wear and damaged horns, has the potential to tear down the overhead line, resulting in long delays and widespread service disruption.

Camlin Rail’s Antoine Pommet spoke about Pantobot to an interested audience in Forum 2.

Cubis Systems, from Armagh in Northern Ireland, is engaged within a variety of major projects across the UK, France, Scandinavia, North America and Australia. These range from light rail upgrades to major rail infrastructure projects such as Manchester tram, the SNCF network and HS2.

All of these unique projects involve integrated network access and cable protection systems for telecoms, drainage, signalling and power applications. Cubis’ integrated product approach, developed through innovative partnering and with long-standing approvals from Network Rail and SNCF, incorporates intelligent technical design features for modular, scalable and lightweight composite access chambers, access covers and cable protection products that can be built on-site, simply, safely and with speed of installation.

Excalibur Screwbolts, last seen at the Signalling Innovations Group’s conference in York last November, was displaying its range of threaded anchors for all substrates. These have many uses in both civil engineering and rail applications and can be used to fix various items directly into all major building materials including concrete, brick and timber without the use of plugs or resin.

General benefits of Excalibur Screwbolts include using one anchor for all applications that is quick and easy to install and doesn’t stress/damage the substrate so is good for close to edge fixing. They are easily removable if required, so can be used in both permanent or temporary works, and have found use on both Network Rail and London Underground infrastructure for fixing various items including insulator pots, signalling systems and rail baseplates.

Forbo Flooring – Sifer 2019.

Forbo Flooring Systems, based in Ripley in Derbyshire, was showing its comprehensive and compliant flooring product portfolio for the rail sector. This includes entrance systems, vinyl floors, linoleum floors, textile carpets, flocked flooring as well as adhesives, accessories and installation tools. Forbo floor coverings are fully certified to suit many types of trains and are certified according to EN 45545-2 with a minimum rating of HL2.

The security afforded by 30 years’ experience, financial independence and a continuous product development program is further assurance of the company’s dependability, as representatives from the office in Villeneuve-Loubet, on the French Mediterranean coast between Nice and Cannes, were on hand to explain.

HVR International, from Jarrow in Tyne and Wear, pioneered the development of carbon ceramic resistances that are now used worldwide in high-voltage, high-energy, power electronics and traction applications. Today, the company’s products are used worldwide by the likes of Alstom, ABB and Siemens.

Specific products on display included SR-series compact power resistors, including the world’s first 10kJ resistance for PCB mounting, ‘Cool Power’ modular water-cooled resistances and ‘Multi-Brake’ braking resistors made by HVR Pentagon in Tyseley, Birmingham.

Pandrol is now under one brand. This is the group stand at Sifer 2019.

Familiar names

Many other exhibitors would be familiar to UK engineers. Alstom has approximately 8,650 employees in France. Its Petite-Forêt site, in the Hauts-de-France region, is its centre of excellence for the design, development, manufacturing, testing and validation of railway equipment such as metros, tram-trains and double-deck trains for suburban and regional use.

Alsom’s stand was busy.

At SIFER, Alstom promoted StationOne, its autonomous online marketplace, dedicated to the railway sector, that connects professionals and is designed as an efficient way to both promote and access the broadest possible range of parts, commodities and services for all areas of the rail sector, including trains, infrastructure, depots and stations.

Amberg Technologies was in Lille, promoting its comprehensive solutions and services for tunnel and rail surveying, geotechnics and geophysics.

Associated Rewinds had a busy show – Sifer 2019.

Focused exclusively on the re-manufacture, service and repair of AC and DC traction motors for trains, trams and metro systems, Associated Rewinds has been in operation in Dublin since 1986. Now a leader in rail traction technology, it partners owners, operators and manufacturers of rail vehicles worldwide.

Cembre, the leading manufacturer in Italy and one of the largest European manufacturers of crimp connectors and cable tooling, offers certified solutions for electrical connections inside convoys and railway locomotives, putting its electro-technical experience at the service of railway companies by developing solutions for electrical connections and the maintenance of railways.

Finland’s EKE-Electronics, which featured in Rail Engineer’s recent article on speed control for trams (issue 173, April 2019), was in a prominent position close to the main entrance. The company provides technology for system integration, train automation, train communications and improved safety. The range includes train control and management systems (TCMS), train communication networks (TCN), vehicle control units (VCU), gateways (MVB, WTB, CAN, serial links, Ethernet), Ethernet train backbones (ETB), Ethernet switches, remote input/output modules (RIOM) and train event recorders.

Frauscher Sensor Technology showed how its wheel detection systems, axle counters and tracking solutions allow system integrators and railway operators to obtain the information they need to run, monitor and protect their operational network.

GAI-Tronics uses state-of-the-art technology to meet the demanding communications needs of the rail industry. It works closely with French partner AE&T for all communication projects, the two companies combining their respective product expertise, technical knowledge and business experiences.

Geismar designs and produces solutions for the laying, maintenance and monitoring of railway tracks and overhead lines. For almost a century, teams from Geismar have been developing rail transport wherever there are rail networks, conventional, urban or high-speed.

The HIMA Group is a leading independent provider of smart safety solutions for industrial applications, with more than 35,000 TÜV-certified safety systems installed worldwide. In the global rail industry, HIMA’s CENELEC-certified SIL4 COTS safety controllers are leading the way to increased safety, security and profitability.

Focussing on securing rail networks through robust network communications with enhanced security functions and easy-to-use network management software, Moxa has deployed over 500 networks worldwide for CCTV, CBTC, TCMS, passenger Wi-Fi, and condition monitoring systems.

Nord-Lock was showing its self-locking fastener systems for use in both rolling-stock and track applications, while Pandrol, which actually belongs to the French Delachaux Group, also had an impressive stand which emphasised the fact that all of the product is now branded Pandrol.

Schwihag, manufacturer of components for switches and turnouts, was showing how use of its products can reduce maintenance costs and help protect the environment. Sekisui had examples of its FFU (fibre-reinforced foamed urethane) sleepers, which have now been fitted to more than 1,500 km of track worldwide.

Trimble’s disolay at Sifer 2019 attracted interest.

The German office of American positioning systems manufacture Trimble was at Sifer, demonstrating its solutions for efficient alignment planning and accurate mapping of fixed assets as well as precise track measurement and construction.

Westermo, the Swedish supplier of data communications equipment and a company well known to Rail Engineer readers, displayed a range of equipment that is used in the demanding field of rail telecommunications and offered visitors advice on the best solutions for their applications.

And finally, Zöllner had a stand on which it was exhibiting its range of track warning systems that keep rail workers safe in live railway environments.

Conferences, round-tables and networking

The exhibition stands weren’t the only attraction at SIFER. Two seminar theatres hosted a range of presentations, seminars and round-table discussions on subjects as varied as Big Data (Capgemini), logistics for railway worksites (SNCF), innovative connectivity solutions (Harting) and COTS for the railway (HIMA).

The seminars and conference sessions at Sifer 2019 proved to be popular.

The Networking evening after the show closed on the middle day proved popular, with exhibitors and visitors alike taking the chance to mingle and talk over the events of the day and the latest news from the industry.

As always in France, the catering was of a high standard. SIFER’s restaurant puts the arrangement at British shows to shame – not a criticism of UK organisers but a reflection on France’s views on food.

So, well fed, well informed and well impressed, it was time to head off to Lille Europe station again and, thanks to Eurostar efficiency and the time difference, to arrive back in St Pancras just half an hour later!

Hopefully, more Brits will cross the channel in March 2021, when SIFER will once again open in Lille and show what the French rail industry has to offer.

Get set for Railworx

The rail industry’s new outdoor civil and systems show is just weeks away

Railworx is a new-for-2019 rail industry show with a difference that takes place next month at the East of England Arena, Peterborough. The first clue is the venue, which is predominantly outdoors. Exhibitors book a six metre by 12 metre stand and then have plenty of space to show off even large equipment. There is, however, an indoor exhibition hall which will appeal to companies that prefer a more traditional exhibition environment, with shell-scheme stands and carpets.

The second clue is in the byline – “Your Outdoor Rail Civils and Systems Engineering Show”. Railworx is aimed squarely at those companies that undertake civil engineering – be it working with structures, earthworks, sea defences or station buildings – and railway systems such as signalling, telecoms, electrification and traffic management.

Organised by the experienced team at Rail Media that has managed and developed other outdoor rail industry shows, Railworx goes much further as it highlights far more of the engineering that goes into the UK’s railways. It will appeal to all those involved in station refurbishment, resignalling schemes, bad-weather resilience, infrastructure maintenance and reconstruction, high-speed communications, electrification and power, systems engineering, building information, remote monitoring and so much more.

Demonstrations, some of them muddy, will be a feature of Railworx.

Equipment will be shown working, either on the stands or in the special demonstration area. This is sure to be a major draw and will be well organised, as Railworx is being presented alongside the well-established Plantworx show for the construction industry. Organised by the Construction Equipment Association, Plantworx attracts major exhibitors such as JCB, Caterpillar, Doosan and others, all with large stands and interesting demonstrations.

A total of 15,000 people visited Plantworx in 2017. It takes place every two years, so this year the combined Plantworx/Railworx show is likely to attract over 20,000 when it takes place on 11-13 June.

Drones are now a feature of railway engineering, like thsi one flying over Amersham.

There will be special features as well, to give visitors even more to see. These will include:

The Drone Zone – they are increasingly in use over the railway, but what can they do?

Network Rail’s dedicated ‘InnovationWorx’ area showing the latest developments by the Signalling Innovation Group and in the fields of electrification and telecommunications;

The major civil engineering contractors, front line suppliers to Network Rail and HS2, looking to connect with their existing and potential supply chains;

Live demonstrations of machinery and plant used for railway civil engineering, including piling, reinforcing, drainage, access, lifting, surveying and monitoring;

Consultants Row’ where the industry’s designers and consultants show what they can do;

A Meet the Buyer event with several of rail’s major players;

The Get SET Zone, designed to help visitors explore employment opportunities and to give them access to services they may need.

In the InnovationWorx zone, Network Rail will be showing off the latest developments from its own research and from its suppliers. Presented by the Signalling Innovation Group, but also taking in the latest developments in telecommunications, electrification and the Digital Railway, InnovationWorx will include the latest technology from 33 Network Rail suppliers, all in one area.

The Railway Industry Association is assembling a group of buyers and procurement specialists from major UK railway companies and contractors for a Meet the Buyer event at Railworx.

These important buyers will be holding meetings on site so that visitors and exhibitors alike can arrange discussions, present their offerings and hopefully plan to meet again to discuss cooperation in more detail.

The Get SET Zone is designed to help visitors explore employment opportunities and to give them access to services they may need to get a new job, get back into work, or get their first job. Recruitment job board RailwayPeople.com will be hosting a Recruitment Wall, on which exhibitors can post their vacancies and visitors can see what jobs are available, while a number of recruitment company directors will attend each day to speak about the industry. Julie Wilkinson CVs will be providing a CV writing service and MIND will be offering free advice to visitors about mental health support for the workplace.

Many well-known names will be amongst the exhibitors. There is only space here to detail a few of them, but all can be found on the Railworx.com website.

Mixamate’s all-in-one pumping trucks reduce the hassle of mixing concrete on site.

Mixamate (RE8)

Mixamate is the UK’s leading provider of mix-on-site concrete and screed. Unique all-in-one concrete pumping trucks provide the delivery, mixing, and pumping of concrete from a single vehicle. This greatly reduces the hassle traditionally associated with mix on site works, while the on-board hose allows for the pumping of concrete from up to 100 metres away.

This service has proved particularly popular within the rail sector, where pours are often required outside of normal working hours or at short notice. Mixamate works regularly with rail industry specialists such as Hochtief, BPH Rail, Sonic Rail Services, and others.

This service is also available for screed, and both liquid and dry mixes can be provided. The pumping trucks carry on-board computer systems that electronically weighs every single ingredient that goes into the mix, resulting in batching plant quality concrete that is vastly superior to standard volumetric mixers.

Visitors can find Mixamate on Stand RE8 at this year’s Railworx show.

Peli Products will have its full range of portable trackside lights on display at Railworx.

It all adds up to a fascinating few days, so be sure to go along to the East of England Arena, from Tuesday 11 June to Thursday 13 June, and see Railworx for yourself.

“Hugely impressive!”

Francis Paonessa reflects on his time at Network Rail

When Dr Francis Paonessa joined Network Rail in the summer of 2015 from Bombardier Transportation, where he had been managing director of the train manufacturing and servicing business in the UK, he did so to head up Infrastructure Projects (IP) – the national organisation charged with delivering major enhancements on the railway network.

Now, with new CEO Andrew Haines pushing forward with a policy of devolution and decentralisation, the work of Infrastructure Projects will be undertaken by the five regions and 13 routes that are being set up. As a result, Francis left Network Rail at Easter.

Before he left, he took the time to meet with Rail Engineer at the company’s offices in Derby to look back at his five years in railway infrastructure, Infrastructure Projects’ achievements in that time, and his personal experiences.

Great expectations

HMS Mersey – the last ship built at Vosper Thornycroft under Francis Paonessa.

On the face of it, Francis’ experience at Bombardier, and before that at naval shipbuilder Vosper Thornycroft, had got him used to major manufacturing on fixed sites. The railway is not manufacturing, and it takes place on very long, thin sites, in the open, all over the country. On the face of it, a very different experience.

“Actually, I was expecting a lot of similarities,” Francis demurred. “The theme that ran through ship building, at Bombardier and here is that of large-project management and of engineering-led, low-volume manufacture.

“Ship building was the ultimate low volume manufacturer for the complexity of the design that you did. It was a massive design effort that resulted in the construction of one, two or three ships.

Francis Paonessa at Bombardier, celebrating 175 years of train building in Derby.

“Bombardier was very similar, with complex train integration and system integration, but for me it was a dream of then having maybe 100 of them to build. That was big volume and there was a lot of opportunity for continuous improvement that was much more difficult to do in ship building.

“Coming to Network Rail, I was expecting a large project management system, an integration-type business, but again, ultimately, very low volume manufacture. It’s an interesting mix of big projects like Thameslink or Birmingham New Street or some of the other stations where they are true one-offs, together with a lot of repetitive work where bringing my manufacturing experience in really helped.

“Track is very repetitive, and, actually, so is electrification more than anything – a logistics exercise rather than a complex design. There is nothing in electrification that is difficult in itself – it’s the amount of it that is difficult, and the integration with the railway and getting access to it, and working with the local community when you’re raising bridges, shutting bridges and demolishing bridges. There’s a lot of similarity, but also some things which are quite different.

“What I did find surprising was that so much of the enhancements were still in the development phase. That was not what I was expecting. It was fine up until reclassification, when the accounting process that we had put in place to cope with the fact that so much was in development was no longer fit for purpose. It switched life from being ‘Is it value for money? Is it efficient spend?’ to ‘Is it within budget?’ which sounds similar but is a fundamentally different approach.

“The railway had to switch from a whole approach, and a whole CP5, of ‘Is it efficient spend?’ to ‘There is a finite budget and you’ve got to design within it’. We were not prepared for that significant change. In fact, when I arrived – and that was only a couple of months before we reclassified – the conversation was more about borrowing money than it was about recognising what a fundamental shift that would make to the whole approach to the business.”

Hendy Review

Reclassification caught many people out. When Network Rail became an arms-length central government body, it was thought that this was purely an accounting exercise and everything would stay much the same. It wasn’t, and it didn’t.

Previously, Network Rail had to plan several years ahead when it applied for government funding, which was provided on a five-year cycle. Some projects, particularly those which would be carried out over a long period of time, or which would be started late in a control period, were therefore costed at very early stages of the project, often before the design was complete or work such as ground surveys had been undertaken.

This was not especially Network Rail’s fault. Money needed for a project scheduled to take place in the third year of a control period had to be applied for up to two years before the start of that period, or five years before construction would take place. So much of the cost calculation was based on a very incomplete design.

As a result, the costings were often wrong, sometimes wildly so, and almost always underestimated. But that didn’t matter too much as Network Rail could borrow the shortfall by issuing its own bonds and other measures.

With reclassification, that all stopped. No longer could Network Rail borrow extra capital, it was to be on a fixed budget which would come direct from government.

Which left Network Rail in a pickle. While many projects were running well, and financially under control, several of the ‘early estimate’ projects were substantially underfunded, but still had to be completed. They were planned and costed under one regime, but were now to be financed under a new and different regime, and that would be impossible.

Network Rail chairman Sir Peter Hendy was asked to conduct a thorough review of the enhancement programme in England and Wales to see what could be delivered in an affordable and timely way within the funding period to 2019.

Hendy’s proposal was to complete all of the work that had been agreed, but over a longer timescale. So, the money allocated for the period up to 2019 (in CP5) would then fund a reduced amount of work, with the remaining projects funded from a new budget for CP6 (2019-2024).

As part of this exercise, Francis and his team were asked to reduce costs as much as possible.

Francis delivering his keynote speech in the Rail Engineer Seminar Theatre at Infrarail 2016.

Value engineering

“Firstly, we didn’t re-estimate the projects,” Francis explained. “There wasn’t the time to do that as part of the Hendy review. That’s a big misconception that people have, they think that Hendy was a whole reset of the process. It wasn’t. We used the estimates that we had at the time. What we presented to Peter, and then Peter ultimately recommended to the Department for Transport, was the prioritisation of the projects and the likelihood of them being delivered on time with the schedule that went with them.

“When you added it all up, we had £193 million worth of extra stuff to deliver than we had money for. So, we had to value engineer £193 million worth out.”

This figure was not about slippage, it was a genuine need to reduce the cost of current projects by £193 million. In addition, Sir Peter Hendy had assumed that about 10 weeks’ work, or £500 million, would slip into CP6 from CP5. But the £193 million is on top of that.

“It was interesting,” Francis recalled. “We classed value engineering as whether we could deliver the same passenger outputs or benefits for less. That drove a whole lot of innovation.

“In the end, we delivered about £240 million of value engineering, so we came out on the right side.

“Because we didn’t re-estimate Hendy, we worked with the DfT and University College London who did a whole piece of work looking at estimating of early rail projects to cope for optimism bias. If you apply those optimism bias percentages, which we’ve now included in later estimates to the Hendy portfolio, it would have added about another £1 billion to the cost. We had this massively significant headwind buried within the budget that wasn’t re-estimated.

“When we look at our value engineering, we also then delivered, on top of the £240 million, another £500 million of value engineering which was offset by headwinds.”

The team also looked into Cause Association Modelling (CAM). This looks at the links between risks, and how one risk can affect another and so skew the risk profile. The calculation was that, across the portfolio of work, an extra £300 million was needed to cover those risks.

“We spent the £300 million – we saved £500 million,” Francis claimed. “This offset headwinds in the portfolio and then we saved another £240 million through value engineering, which kept us within the Hendy budget. Having now just gone through the end of CP5, we’ve delivered the £15.3 billion of Hendy within a fraction of one per cent of the budget we set out over four years ago which, personally, I think is hugely impressive, given where we started.”

Francis was a regular visitor to work sites, even over his last weekend working for Network Rail over Easter 2019.

Back to renewals

In CP3 and CP4, work was concentrated mostly on renewals. CP5 saw a large upswell in the amount of enhancements taking place. Now, for CP6, the emphasis seems to be back on renewals.

“There’s still a lot of enhancement spend in CP6, let’s be clear,” Francis commented. “There’s about £10.5 billion that is inherent within the funding that we’ve got to deliver within CP6, which is still an enormous amount of money to go and spend on enhancements.

“But I don’t think we’ll see another control period like CP5. £18.7 billion invested in enhancements and £14.4 billion worth of renewals within Network Rail over the last five years. I think Nichols worked out we delivered 22 per cent of all UK infrastructure. That’s a lot for one organisation to do, particularly when we have the constraints of access to the railway.

“You asked at the beginning about the big difference between working in ship building and working in Bombardier, it’s ten times easier to work in a fixed site where you don’t have to break the work up into 40,000 chunks. We take about 40,000 possessions a year to deliver our work, that’s 40,000 opportunities to get it wrong and to either overrun or put the travelling public at risk.

“It’s very challenging to do and it’s totally unlike any other business I’ve been in. With a brownfield site, and we’ve been fortunate to work on some of those, Stafford was a really good example – where the vast majority of the work was off railway and the only railway interfaces were the turn off, then it’s a very different way of working and a very different way of thinking because you’ve got 24/7 to do it in. You haven’t got to wait for the last train to go by, take the possession, get onto the railway, transit to where you want to work and then get back off again.

“I think our average possession time is 5 hours and 35 minutes, it’s not a lot of time, given the demands and the expectation of handing back on time and handing back safely, but we are now managing to fit 38 per cent more spend into each possession minute than we were at the start of the control period.”

Reliability and contingencies

One of the other improvements that have come about over the last five years is in the reliability of plant, and the reduction in overruns and additional costs they can cause.

“The track team has put an enormous amount of effort in with the equipment providers to drive down our RRV failures,” Francis commented. “If an RRV fails in the dig, you’re really stuck because it’s not an easy piece of equipment to fix. It’s sat in the way and trying to get a 30-tonne bit of kit out of a hole isn’t that easy when you’ve got engineering trains on one side and you’re trying to work. And if you’ve only allowed for four hours of contingency time, you’re hard up against it with time.

“Typically, at the bank holidays, we lose about half a percent of the work because we don’t start it. It may be weather driven, usually, or there’s been some operational incident or a late running train. Whatever it might be, we’ll be saying we’ve passed the cut-off point in our contingency planning and we won’t start.

“Then we lose about another half a percent of work in trying to guarantee on-time hand back. That’s been pretty consistent now for the last three years or so. The reason it’s not turning into overruns is that the teams have been far better at planning their work in a very structured way so that we can get the core bit of work done.

“Welding and stressing might be a really good example for a track job. If we’re planning to hand it back at 50mph, we might not do the welding and stressing at the end. We might do it in midweek nights.

“We can get the track in the ground, we can get it plated and we can get it tamped and we can usually hand back at 50mph. Typically, within a week, we will have handed that back at the line speed. It’s that structuring of the way in which we do the work that means that we can cope with these failures. Otherwise, the only real way of doing it is to put more contingency time at the end and that way you just get less work done.

“Of course, there are some jobs where you just can’t do that. Bridge renewals, we’ve got two bridge renewals coming up at Easter so we will be taking off the track, taking out the bridge, rebuilding the bridge, putting the track back in the four-day period. You can’t do half the bridge. Things like bridges are particularly challenging because once you’ve started you’ve passed the point of no return.

“For those, we don’t have a bigger contingency, we just have a lot more planning. The basic problem with a bridge is we’ve got four days over a bank holiday, a weekend if they’re smaller ones. We’ve got the time we’ve got and we just have to make sure that we sequence the work in the way that allows us to get that done.

“Where we might build some more time in is if, say, it’s being delivered by road crane, which can suffer from wind issues, but we’re delivering more now by self-propelled modular transporters, so we don’t often have the wind issues. We don’t have to put that contingency in, but we might still have welding and stressing at the end. We might have hand rails, guard rails and all sorts of bits that we might be able to curtail.

“Frequently, we might have a four hours float and four hours of extra contingency and that, statistically over the last four years, has given us a very secure hand-back profile. The problem is, there is absolutely no guarantee that the time that we’ve got will cope with everything and that’s why we still have a few small overruns during the year.

“It isn’t luck we’ve ended up where we are. There has been a whole host of learning those lessons, process improvement, sharing of best practice right across the organisation that the teams have embraced and done a fantastic job in embedding and getting us to the point now where we have a far, far more dependable delivery.

“Also, our visibility going forward of where issues are, is far better. We have now actually got time to fix problems before they materialise into a possession overrun. Is that perfect? No, it’s not and it’s fairly difficult delivering the 11,500 projects that we have and £5.5 billion worth of stuff that we’ve done just this year, to sit and really shout that from the roof tops because we are not a perfect organisation.”

The real heroes

“Celebrating success, and particularly celebrating success with the projects that are the big flagship ones, is one of the big leadership challenges within the organisation, because it’s the teams that deliver renewals that are real heroes,” said Francis.

“They are in frequently very small teams. They might be delivering multiple small projects themselves. They’re doing a great job with the supply chain in delivering those, but they’re not London Bridge. Renewals are the vast majority of the possessions that we take and the teams deliver them, time and time again faultlessly, and people don’t notice. We renewed 300km of track last year and no one noticed. The signalling teams renew and replace hundreds of SEUs (signalling equivalent units) and people don’t really notice. The new signalling scheme, they don’t notice it having been re-locked to a different location or we’ve closed signal boxes or we’ve modernised – all that stuff just happens.

“Passengers are not interested, and rightly they shouldn’t be, but making sure the narrative within the business equally recognises that the teams that we’ve got working incredibly hard, delivering those far less exciting visual renewals as the one or two flagship projects that we might have ongoing, is an important balance.

“Of course, the external narrative rightly tends to focus on the one or two projects that don’t go as well as we’d hope. Because of the negative focus we get when it goes wrong, keeping those teams motivated who are in the spotlight working, day after day, on really difficult engineering projects, is challenging. Huge credit to the teams who get up every morning and come in and put their best work in on a project that’s difficult and, because of where it is, it’s frankly, no matter what they do, never going to be seen as a success.”

Failure and success

When Francis joined Network Rail in 2014, it was three months after reclassification had been announced but two months before it was implemented.

Six months later, at Christmas 2014, there were the well-publicised overruns at King’s Cross and Paddington that so-badly damaged Network Rail’s reputation. It was a real baptism of fire.

“Joining an organisation and three months in to find that you are forecasting to be several billion pounds overspent already three months into a new control period, is not good,” he remembered. “To then badly let customers down at Christmas was really not good. You suddenly find that you’ve got an organisation, in the broadest sense, of people who are trying their absolute hardest to do a good job, but aren’t delivering on that. At the same time, you’ve got a phenomenal workload to deliver. To transform an organisation whilst having a phenomenal amount to deliver is really difficult.

“Probably my only regret is that we’ve now got to a point where I’m extremely proud of the organisation, the capability that sits within it, the detail of the planning which underpins CP6, and it would have been fantastic to run that machine at the plans that we’ve got for CP6 for two years and absolutely smash it out of the park. I sadly won’t have the opportunity to do that, but the new regional managing directors will with the team that we’ve built.”

Devolution

The devolution of IP, being promoted by new CEO Andrew Haines, isn’t, in Francis’ opinion, going to be as much of a change as people think.

“One thing to clarify, IP isn’t a centralised structure,” he explained. “Because we’re a national function, there’s quite a lingering perception that we’re a team that sits in the middle somewhere and does stuff across the country. We’re far from that. There are seven delivery teams – four regions, northern programmes, track and signalling, supported by five functions. 96 per cent of the people in IP sit in those delivery legs. About 186 people sit in the functions. We are probably the most devolved part of Network Rail already and the teams sit geographically dispersed.

“We’re sitting here today (in Derby) and part of my signalling design team are sitting downstairs and my East Midlands regional enhancements team are 800 yards down the road, which shows how widely 4,800 people in IP are geographically distributed.

“When we move into a devolved structure with the routes, a large percentage of people in IP won’t be moving anywhere. They will still be sat at the same desk in the same location next to the same people doing the same job but working within a new regional structure. What we’re doing is changing the accountability, and particularly the responsibility for the delivery activity, from it being a national function to a devolved regional structure. Accountability for enhancements and renewals will ultimately rest with the new regional managing directors.

Francis departed Network Rail, not before Easter, but immediately afterwards, having visited work sites and encouraged staff on his last day. He says he has no future plans at present, but no doubt he will pop up somewhere before too long.

Rail Engineer wishes him well in the meantime.
