Mott MacDonald working on improving the railway’s response to signalling failure

Engineering and design consultant Mott MacDonald is undertaking its first piece of work for the new Network Rail design services framework, supporting the development of a new system to support degraded mode working on the railway during signalling system failures.

The DMWS project is part of Network Rail’s research & development portfolio, a £245 million investment programme over CP6 to drive improvements to the safety, performance and efficiency of Britain’s railway infrastructure.

DMWS aims to reduce delays to passengers and train services by deploying a range of new technologies to quickly restore limited train services whilst the primary signalling system is restored. Mott MacDonald is working as design consultant and technical advisor for Network Rail, providing support on elements including signalling interfaces, telecoms and power. Its technical advisory role will include:

  • Development of design, installation and testing standards
  • Signalling interfaces technical advice
  • Trial site investigations
  • Product development support

Mott MacDonald previously worked on the feasibility stage of the project in 2018 and will continue to support Network Rail through to an operational trial, currently expected to occur in 2022.

The DSF is a key framework for Network Rail. The framework was awarded in December 2019. Mott MacDonald was awarded three lots on this national framework.

SPECIALIST AREAS Rolling stock, mechanical equipment, project reports, executive interviews


Nigel Wordsworth graduated with an honours degree in Mechanical Engineering from Nottingham University, after which he joined the American aerospace and industrial fastener group SPS Technologies. After a short time at the research laboratories in Pennsylvania, USA, Nigel became responsible for applications engineering to industry in the UK and Western Europe. At this time he advised on various engineering projects, from Formula 1 to machine tools, including a particularly problematic area of bogie design for the HST.

A move to the power generation and offshore oil supply sector followed as Nigel became director of Entwistle-Sandiacre, a subsidiary of the Australian-owned group Aurora plc. At the same time, Nigel spent ten years as a Technical Commissioner with the RAC Motor Sports Association, responsible for drafting and enforcing technical regulations for national and international motor racing series.

Joining Rail Engineer in 2008, Nigel’s first assignment was a report on new three-dimensional mobile mapping and surveying equipment, swiftly followed by a look at vegetation control machinery. He continues to write on a variety of topics for most issues.
