Thameslink, Southern and Overground trains in South London are to be disrupted for seven days over October half-term as Network Rail brings an upgraded signalling system online. Officials say the work will mean that no services will run on parts of the network for seven days, from Saturday, October 26, to Friday, November 1.

The enhancements taking place between Crystal Palace, Tulse Hill and Peckham Rye are part of a £400 million programme of investment in track and signalling upgrades that Network Rail is delivering in South London, bosses say. They add that a previous phase of signalling improvements between East Croydon and London Victoria in 2022 saw signalling related delays 'cut by more than half'.

Network Rail says that it hopes the current phase of upgrades will deliver similar benefits for passengers.

From Saturday 26 to Tuesday 29 October there will be an amended service on routes between Highbury & Islington and West Croydon and New Cross. From Wednesday 30 October to Friday 1 November some Crystal Palace and New Cross services will be re-timed. Please plan ahead and check before travel.

Lucy McAuliffe, Network Rail’s Sussex route director, said: “It vital that we continue to invest to modernise our assets and give passengers the delay free journeys they expect. Signalling upgrades between East Croydon and London Victoria in 2022 saw delays cut by more than half and we are expecting this phase of signalling upgrades in the Crystal Palace, Tulse Hill and Peckham Rye areas to deliver a similarly impressive reduction in delays when it comes into use.

“We know the work means days of major changes to journeys for passengers and we are sorry for the disruption. Please plan ahead, look out for further updates and follow travel advice.”
