London Overground runs services across a large part of London and Hertfordshire, with 112 stations on nine different routes
The London Overground turned ten years old in 2017, having grown by 470 per cent since it began operations. Launched in 2007 the London Overground, known to Londoners as the Orange Line, runs along a circular route around inner London, connecting 23 boroughs of the capital city and parts of southern Hertfordshire.
In November 2016 Arriva Rail London took over London Overground network, and will support TfL in delivering further improvements for customers on the already hugely popular network. The vast majority of the London Overground network is operated on Network Rail tracks, which are also used by other rail operators, freight and maintenance services.
189 million journeys were made on the Overground in the year 2016/17, compared to just 33 million in 2007/8. One third of Londoners live within walking distance of a London Overground station and overall satisfaction scores were at 90 per cent on the 2017 National Passenger Survey.
London Overground night services started operating in December 2017 on Fridays and Saturdays along the East London route between New Cross Gate and Dalston Junction.
In 2018 it was extended to Highbury & Islington. The service runs on weekends between Highbury & Islington and New Cross Gate.
London Overground operates the Bombardier Electrostar Class 378 on its network, these are supported by 54 Class 710 trains.
Bombardier signed a contract with TfL in 2006 for the maintenance of London Overground trains, in March 2018 that contract was extended to 2030 at an additional value of £106 million.
