We operate one of the busiest networks in the country

We operate one of the busiest networks in the country, providing trains services between seven London terminals and linking south-east London, Kent and parts of East Sussex.

This includes a mixture of high-capacity commuter style services on our Metro routes, longer distance Mainline services as well as the UK’s first and only domestic highspeed service, operated by 140mph Javelin trains.

We are in an Alliance with Network Rail Kent Route – the rail infrastructure owner and working closely together to deliver improved services.

The operation of all Southeastern services transferred from London South Eastern Railway (LSER) to SE Trains Limited on 17th October 2021.

SE Trains Limited is a wholly owned subsidiary of DfT OLR Holdings Limited (known as DFT Operators, or DFTO) the Public Sector Owning Group which also operates LNER, Northern and TransPennine services.
