Highlights of the work completed during the 9-day line closures – Balcombe Tunnel Junction renewal

  • Extensive drainage works in Balcombe Tunnel: The Victorian brick culvert drainage system in one of the South East’s longest railway tunnels had a build-up of silt and other debris, along with damage to brickwork. This compromised the drainage system and led to flooding, which in turn caused signalling and power supply problems
  • Balcombe Tunnel Junction: Renewed and upgraded this junction, replacing 600 metres of track, improving the layout of the junction and replacing switches and crossings, which allow trains to easily move tracks
  • A complete renewal and upgrade of the lineside signalling and power systems between Haywards Heath and Preston Park, with more reliable, modern high-tech equipment
  • Extensive work at stations, including platform improvements, cleaning, repainting waiting rooms, ticket offices and station buildings, repairing and replacing footbridges, and repairing fencing as well as tidying up plants and hedgerows.

Below is just some of the work carried out during the weekend closures:

  • Balcombe Station – Footbridge foundations prepared
