What is the Brighton Main Line Improvement Project? open

The Brighton Main Line Improvement Project is part of a £300 million government-funded programme to tackle delay hotspots and boost the reliability of the railway in the south east, including the expanded Thameslink network. The project is an engineering programme being carried out by Network Rail, with the support of its partners, UK Government, Southern and Govia Thameslink. The Brighton Main Line is a key rail route, connecting Gatwick Airport and the south coast with London, and is used by 300,000 people each day. The section of the rail network targeted is responsible for more delays to Southern and Thameslink services than any other. Without this programme of activity, reliability will get worse over time and lead to even more delays.

What work is being carried out? open

The improvement work focuses on four Victorian-era tunnels – Balcombe, Clayton, Patcham and Haywards Heath – and the railway which runs through them. A major programme to stem leaks into the tunnels and provide reliable drainage away from the tracks is taking place, while some track is being replaced, third rail power system and signalling is all being replaced or upgraded. Elsewhere, track is being renewed, sets of points, which enable trains to switch between tracks, are being replaced and fencing is being improved to deter trespassers.

Why is this happening? open

Without this programme of work, reliability on the Brighton Main Line will deteriorate in the months and years ahead, leading to more delays for passengers travelling between London and the south coast. The closures will allow Network Rail engineers to renew and upgrade this stretch of railway.

Will the work be completed on time? open

We’ll have hundreds of people working round-the-clock for nine days and during the weekend closure dates to complete the planned work safely and on time.
