TRAIN passengers have been warned there will be four days of line closures.

Network Rail has announced the line between Lewes and Seaford will be closed between November 28 and December 1.

Rail replacement buses will be available between Haywards Heath and Lewes and between Lewes and Seaford on each day.

Bus services will also run between Brighton and Lewes and between Lewes and Polegate between November 29 and December 1.

Engineers will carry out the final phase of work on a £25 million upgrade on the line’s old signalling system.

Network Rail investment director Paul Harwood said the upgrade is “much needed”.

He said: “It will provide new state-of-the-art equipment providing passengers with more reliable journeys for many years to come.

“I’d like to thank people for their patience while we complete the upgrade.

“We recognise that there is never a good time to close the railway, but we will be working closely with our colleagues at Southern to ensure people are fully aware of the closures and the alternative travel options available to them.”

Govia Thameslink Railway infrastructure director Keith Jipps added services would be more reliable after the upgrade.

Signal boxes at Lewes, Newhaven Town, and Newhaven Harbour will be closed.

Signalling control of the area will be moved to Three Bridges.

The planned upgrade will increase the number of trains able to travel on the London-Brighton line via Lewes.

The signalling works will also support a rail link for the new aggregates facility at Newhaven Marine, helping to take hundreds of lorries off roads.
