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 in the Brighton Main Line and 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 of the network.

Weekend line closures

Weekend closures of the railway in the Lewes area, for signalling upgrades and other railway works, will take place on:

  • Sunday 2 June
  • Sunday 15 September

Please contact your train operator for more information or visit National Rail Enquiries.

Future work – keeping you informed
