Project Information:

Network Rail engineers will be working to replace all signalling equipment between Lewes and Seaford with new, more reliable technology as part of a £20m signalling upgrade. The signal boxes at Lewes, Newhaven Town and Newhaven Harbour will be closed, with control of the signalling in the area transferred to Network Rail’s state-of-the-art Route Operating Centre (ROC) at Three Bridges.

The work being carried out around Lewes is part of the plan to provide a better, more reliable railway for passengers. The new signalling equipment will be far less likely to fail.

The improvements will allow triple the number of trains to use the line via Lewes as a diversionary route between Brighton and Haywards Heath when the main line is closed.
