London Overground

We launched London Overground in 2007, and since then we have introduced staff at stations while trains are running, Oyster pay as you go facilities, increased the frequency of trains, improved reliability, and opened three line extensions.

We have also refurbished every station, introduced more than 60 new trains and added WiFi at certain stations.

London Overground is now one of the most reliable train operators in the country, and is rated one of the best by customers.

Following completion of the link between Clapham Junction and Surrey Quays in 2012, 30% of all Londoners are within walking distance of an Overground station.

Outer London orbital network

There are four London Overground routes that, together, form an Outer London orbital network:

  • Highbury & Islington to West Croydon/Clapham Junction
  • Richmond/Clapham Junction to Stratford
  • Gospel Oak to Barking
  • Watford Junction to Euston

Managing London Overground

A number of organisations work together to manage the London Overground network, but we have overall responsibility.

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

We also plan and fund improvements and extensions to the network.

In June 2007, we appointed London Overground Rail Operations Ltd to manage the network's stations and trains on a day-to-day basis.

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