London Overground

Tranport for London (TfL) is responsible for London Overground – a group of orbital lines serving many areas of the Capital. Their customers make more than 184 million journeys on the railway each year.

London Overground was launched in 2007 when we took over Silverlink Metro services. It has grown from there:

  • Silverlink Metro services (2007)
  • East London line (2010)
  • South London line (2012)
  • Romford to Upminster and Lea Valley lines (2015)


Around a third of all Londoners are within walking distance of a London Overground station.

Since launching the service we have:

  • Improved the frequency and reliability of trains
  • Opened four line extensions, including 57 new stations
  • Refurbished every station and improved accessibility – more than half are now step-free from street to platform
  • Introduced 65 new trains and added a fifth car to most of them
  • Added WiFi at most stations


London Overground is now one of the most reliable train operators in the country, and is rated one of the best by customers. Every three months we measure customer satisfaction and get consistently high scores.

Outer London orbital network

There are six London Overground routes that, together, form an outer London orbital network:

  • Richmond/Clapham Junction to Stratford
  • Watford Junction to Euston
  • Gospel Oak to Barking
  • Highbury & Islington to West Croydon/Clapham Junction
  • Liverpool Street to Enfield Town, Cheshunt (via Seven Sisters) and Chingford
  • Romford to Upminster
