Work starts on £67M Brighton Mainline upgrade

Brighton mainline upgrade clayton tunnel oct 18 3to2

Network Rail is preparing to overhaul a stretch of railway on the Brighton Mainline this weekend as part of a £67M upgrade to the line.

Work between Three Bridges, south of Gatwick Airport and Brighton include improvements to track, signalling and drainage to stop flooding inside Victorian tunnels.

The line is one of the least reliable in the South East, said Network Rail. The improvements will be the first to be carried out on this section of the line in 30 years.

The work will involve the renewing track inside the Clayton Tunnel, installing new signals between Patcham and Preston Park and replacing electrical circuits between Three Bridges and Balcombe.

Work has taken place at 25 separate sites so far and has included the renewal of 4.3km of conductor rail, 500m of track and 15 signal heads and the replacement of thousands of tonnes of ballast.

The line will be closed during the work.

Network Rail director of route investment for the South East Paul Harwood said: “We are working hard to make the least reliable part of our network better for passengers by upgrading the southern end of the Brighton Main Line.

“We know there’s never a good time to close the railway, which is why we’re working closely with our train operator partners to provide the best advice so that passengers are inconvenienced as little as possible during our works in November and beyond.”
