The Sussex route, which includes the Brighton Main Line and its branch lines, is among the busiest and most congested in the country, carrying 3,800 trains every weekday.

It’s also critical to the economy as it transports high volumes of leisure travellers to Brighton and other south coast resorts, as well as Gatwick Airport.

Over 2018/19, we invested £67m to upgrade infrastructure and tackle delay hotspots as part of the Brighton Main Line Improvement Project, which is expected to reduce delays by up to 15%. We’re still investing heavily to continue improving services for passengers with the Croydon Area Remodelling Scheme (CARS), which will remove the most challenging bottleneck on Britain’s rail network, reducing delays and increasing capacity to meet future passenger demand.

On top of this, we are replacing 2.3km of track between Barnham and Havant, replacing old signalling equipment between Lewes and Seaford, and have proposals to upgrade Norwood Junction station.

Our lead train operators are Govia Thameslink Railway Ltd (GTR) which operates Southern, Thameslink, Gatwick Express and Great Northern services. Together our priorities include introducing the full Thameslink timetable of 24 trains per hour through the central London core, improving reliability on the Brighton main line, removing the Croydon bottleneck; and redeveloping Gatwick Airport station to improve capacity and passenger flows.
