Landport viaduct

Network Rail set to begin work on Portsmouth's Landport viaduct

Network Rail are set to start work this week on Portsmouth’s landmark Landport viaduct meaning no services to Portsmouth Harbour.

Engineers from Network Rail are set to finish strengthening work on the Victorian Landport viaduct.

The metal viaduct was built in 1876 and supports two platforms at Portsmouth and Southsea station.

The viaduct had ten of its 17 spans strengthened in January 2021.

During an eight-day closure between Portsmouth and Southsea and Portsmouth Harbour the remaining seven spans will be strengthened.

This is set to affect South Western Railway (SWR), Great Western Railway (GWR) and Southern services.

Mark Killick, Network Rail’s Wessex Route Director spoke on the improvement work taking place on the viaduct.

Mr Killick said: “Our long-term project to strengthen the viaduct at Portsmouth and Southsea station is almost complete.

“This last eight-day closure will allow our engineers to improve the structure’s steelwork and keep trains running through to Portsmouth Harbour for years to come.

“It’s just not possible to do this level of work on the viaduct with trains still running but I appreciate it’s hard for people who rely on the railway.

“We’re very grateful for their patience with us.

“Customers should plan ahead next week if they can, as buses will replace trains and some journeys will take longer than normal.”

Christian Neill, SWR’s Customer Experience Director commented on the engineering work set to take place.

Mr Neill said: “The improvement work planned in the Portsmouth area in early January will mean a more resilient service for our customers.

“Closing the railway during the working week and at the weekend will, of course, inconvenience our customers.

“I’d like to thank anyone traveling with us during these works for their patience and understanding.”

Once the viaduct is fully strengthened trains will be able to run at full speed through Portsmouth and Southsea.
