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.
We've recently upgraded infrastructure as part of the Brighton Main Line Improvement Project, and we’re still investing heavily to continue improving services for passengers.
The Croydon Area Remodelling Scheme (CARS), will remove the most challenging bottleneck on Britain’s rail network, reducing delays and increasing capacity to meet future passenger demand. The £150m Gatwick Airport station redevelopment will deliver a much-needed capacity increase and improve passenger mobility and accessibility improvements which this critical international gateway deserves.
That's not all. We're investing in smaller but equally important upgrade projects right across the route. Find out more on the Sussex Upgrade Plan page.
Our lead train operators are Govia Thameslink Railway Ltd (GTR) which operates Southern, Thameslink, Gatwick Express and Great Northern services. Together our priorities are to deliver up to 24 Thameslink trains per hour through the London core and remove the bottlenecks and ageing infrastructure that impact passenger journey times and service reliability on our route.
