Network Rail Easter projects cause South East disruption
Work to rebuild a junction at Battersea Park railway station, in south London, will bring travel disruption to passengers over the Easter break, Network Rail has said.
No trains will run from London Victoria to Sussex and Gatwick Airport.
But Southern and Thameslink services will run from London Bridge and London Blackfriars to the coast and Gatwick.
Area director Steve Knight said there would be a good service but different timetables would be in place.
He urged people to check travel information before they travel.
Other work taking place this Easter will see a replacement bus service on the Horsham line to Arundel with extended journey times of up to 60 minutes.
A new signalling scheme is also being brought in around Medway and there will be work to build a new Crossrail station at Abbey Wood in south London.
Network Rail said there would be no Southeastern trains to Cannon Street or London Bridge as a result.
There will also be bus replacements between Sittingbourne, Longfield and Sheerness in Kent.
