Rail passengers on the Uckfield Line are being warned trains and stations may be busier than usual during half-term.
The Brighton Main Line will be totally closed from Saturday, February 16, to February 24, south of Three Bridges.
People from Brighton, Mid Sussex and the south coast are all planning different routes to and from London during the blockade.
Regular commuters from Uckfield and Buxted are expecting trains to be much busier than normal and signs warning of the possibility have gone up at stations.
What’s happening on the Brighton Line?
Network Rail is carrying out the biggest refurbishment of the line between Three Bridges and Brighton in more than 30 years.
Partly funded by the Department for Transport as part of a wider £300m programme, the project is designed to tackle delay hotspots and boost reliability on one of the busiest and most unreliable parts of the network.
The work will renew and upgrade track junctions and signalling, shore up embankments to reduce the risk of landslides and introduce new technology that not only detects potential problems before they occur, but can help the railway recover faster if there is a fault.
There is also extensive work within four Victorian tunnels to stop leaks and drainage issues, which have caused significant delays for passengers in the past.
