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

Managing London Overground

A number of organisations work together to manage the London Overground network, but we have overall responsibility for delivering a seamless service to our customers.

We set the specifications for train frequency, station facilities and overall performance, and are responsible for fares and revenue.

In November 2016 Arriva began to manage the network's stations and trains on a day-to-day basis. Arriva replaces London Overground Rail Operations Ltd which was appointed as operator in 2007.

Network Rail manages and maintains most of the track and signals, as London Overground is part of the National Rail network.

Improving London Overground

We are committed to improving the London Overground network, and have invested in trains and stations since the service began.

The fifth car we added to most of our trains increased capacity on those services.

Gospel Oak to Barking customers will also benefit from eight new trains by November 2018 now that electrification of the line is complete. More new trains will increase capacity on other parts of the London Overground network.

We are also planning a 4.5km extension to Barking Riverside.

Working with Network Rail

Most London Overground services run on tracks owned by Network Rail and shared with other train operating companies. This means track, signalling and infrastructure such as bridges are in almost constant use. Network Rail schedules regular and comprehensive maintenance to ensure everything is in good order.

The network sometimes has to close because Network Rail is doing maintenance or because we are. Wherever possible we schedule our work to take place at the same time as Network Rail.

We usually carry out maintenance at the weekend when there are fewer passengers.
