Portsmouth Rail Line Reopens Following Latest Phase Of Major Upgrade Works

Train services between London and Portsmouth Harbour have resumed following the completion of the latest phase of engineering works on the Portsmouth Direct Line.

Network Rail and South Western Railway carried out five days of work over the May half-term break as part of a wider programme to modernise railway infrastructure across the region.

A key focus of the closure was the ongoing Havant re-signalling programme, which aims to replace ageing signalling equipment in the Havant and Portsmouth area.

Network Rail says signalling failures have caused more than 18,500 minutes of delays on the route over the past year.

The project will see a further £120 million invested in the Portsmouth Direct Line, in addition to the £129 million Farncombe-to-Petersfield signalling upgrade programme already underway.

Once completed in 2028, control of signalling operations will transfer from the Havant Area Signalling Centre to the Basingstoke Rail Operating Centre, with the aim of improving reliability and helping operators respond more quickly to incidents.

During the latest closure, engineers carried out preparatory work for future signalling upgrades, including vegetation management and the installation of materials needed for the next stages of the project.

A number of other improvements were also completed, including the replacement of 18 wheel timbers on Portcreek Viaduct, strengthening work on two bridges between Fratton and Portsmouth Harbour, refurbishment of the footbridge at Fratton station and track upgrades in the Fratton area.

Engineers also cleaned the glass panels on the high-level platforms at Portsmouth & Southsea station.

In total, around 1,660 hours of work were carried out during the five-day closure.

Further work connected to the Havant re-signalling programme is planned for October this year and February 2027.

Tom McNamee, Infrastructure Director speaking on behalf of Network Rail and South Western Railway, said the work would help modernise infrastructure and improve reliability for passengers using the route.

He also thanked passengers for their patience while the upgrades were carried out.
