PASSENGERS are being warned about a four-day railway closure.

Work to complete a “major upgrade” of the line between Lewes and Seaford will take place between November 28 and December 1.

Buses will replace trains on various routes via Lewes.

Paul Harwood, director of route investment for Network Rail, said: “This project will complete the work which was started earlier this year and is a much-needed upgrade to some of the oldest signalling in the country.

“It will deliver modern 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 are working closely with our colleagues at Southern to ensure people are fully aware of the closures and the alternative travel options available to them.”

The project plans to reduce disruption by allowing more trains to use the diversionary route for London-Brighton services via Lewes.

Keith Jipps, infrastructure director for Southern’s parent company Govia Thameslink Railway, said: “This major investment will improve the reliability of signalling and therefore our services for passengers travelling on one of our key Southern routes. Updated bus and train times for the closure period are now online and we advise passengers to check before travelling.”
