Buses are replacing trains across the Brighton mainline today, as major engineering works take place.

It means no trains will run between Gatwick Airport and Brighton, Hove, Lewes or Horsham.

All four tracks are being closed for what Network Rail is describing as a "major package of works", including replacing sections of tracks and renewing drainage systems.

Lucy McAuliffe, Network Rail’s Sussex route director, said: “We know closing the railway is frustrating, and we are sorry for the disruption this causes.

"This work is essential for us as we try and prevent speed restrictions or emergency closures occurring in the future, which would cause even bigger delays at these locations and on the wider rail network."

Replacement buses replace services

Replacement buses will run between:

Three Bridges and Gatwick Airport

Brighton and Three Bridges

Horsham and Three Bridges

Lewes / Cooksbridge / Plumpton and Haywards Heath and Three Bridges.

A diverted Southern train service will run between Brighton and London Victoria calling at Hove, Shoreham-by-Sea, Worthing, Angmering, Littlehampton, Horsham and Clapham Junction.

If travelling between Brighton and London, rail passengers are strongly advised to use this train service rather than the limited replacement bus service.

Passengers should be aware that if they are travelling by replacement buses on routes between Brighton, Lewes, Haywards Heath, or and Gatwick Airport, they will need to change buses at Three Bridges for a separate shuttle bus service between Three Bridges and Gatwick Airport.

This is because there isn’t sufficient space at Gatwick Airport to set up the temporary queuing systems that are needed.
