Project information:

The improvement works on the Brighton Main Line are a key 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 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.
