We're replacing old signalling between Lewes and Seaford with more reliable technology to reduce delays for passengers.

This is part of our ongoing investment to improve the railway on the south coast.

The signal boxes at Lewes, Newhaven Town and Newhaven Harbour will close and the signalling control of the line move to our state-of-the-art route operating centre at Three Bridges.

The project will be replacing old signalling equipment and replacing it with more modern, more reliable technology, which means there will be fewer delays for passengers in this area.

Line closures

As we now complete the work on the signalling upgrade in the Lewes area, the line will be closed:

  • Thursday 28 November – Sunday 01 December 2019

Track work in the Seaford area

Buses will replace evening trains between Lewes and Seaford from Monday 14 October during three weeks in October and November.

Date and time:

  • 14 October – 17 October 2019 between 20:00 – 23:59
  • 28 October – 31 October 2019 between 20:00 – 23:59
  • 4 November – 7 November 2019 between 20:00 – 23:59

Routes affected:
Southern between Brighton and Seaford.

As a result, buses replace trains from 20:00 until the end of service.

The last trains to run will be:

  • The 19:41 Brighton to Seaford service.
  • The 20:25 Seaford to Brighton service.
