Portsmouth landmark viaduct to be refurbished during January

One of Portsmouth’s most prominent Victorian railway structures is to get some vital engineering attention in January 2021.

Built in 1876, the Landport Viaduct supports two platforms at Portsmouth and Southsea station on the line to the harbour. It needs a week’s worth of strengthening, without trains running over it. In addition, a separate project will see new track laid and a bridge rebuilt near Cosham.

This means that, between Friday 1 and Sunday 3 January, plus Sunday 17 January, the line from Fareham to Portsmouth Harbour will be closed for the Cosham project

For one week, Between Monday 18 and Sunday 24 January, the line from Portsmouth & Southsea to Portsmouth Harbour will close, with the closure extended Cosham and Bedhampton on Sunday 24, for Landport Viaduct strengthening.

During the work, trains will start and finish their journeys earlier, some will call at additional stations or be diverted, while others will be replaced by buses.

Mark Killick, Network Rail Wessex route director, said: “We know any planned changes to train services can be disruptive to passengers, but both projects will provide a more reliable railway in Portsmouth. By doing this work all together, and especially the seven-day closure, we will save many more weekends of potential disruption.

“We’re proud to be the custodians of some very old Victorian structures, and one of the challenges we face is running a frequent and busy train service over the top of them, while keeping them in top condition.”

Landport viaduct is supported by 17 spans with seven being strengthened during January’s line closure. The remaining 10 will be strengthened at a later date.

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.
