The planned improvement work on the Brighton Main Line is 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.

The performance on this part of the network needs to be improved and we are working to deliver this for you.

The section of the rail network where the work is taking place is responsible for more delays to Southern and Thameslink services than any other.

Without this programme of activity, reliability on the Brighton Main Line will get worse over time and lead to even more delays.
