London Overground The London Overground (also known as the Overground) is a suburban rail network in the United Kingdom. Established in 2007, it serves a large part of Greater London and parts of Hertfordshire, with 112 stations on several routes. The network forms part of the National Rail network, but under the franchise control and branding of Transport for London (TfL). Operation has been contracted to Arriva Rail London since 13 November 2016.
Southbury Loop The Southbury Loop (formerly known as the Churchbury loop) is a line linking Edmonton Green, in north-east London, to Cheshunt. It was opened by the Great Eastern Railway in 1891 although initially it was not very successful and was closed to passenger traffic in 1910. Goods trains continued to use the line although in World War I passenger services were reinstated for munitions workers. Once the war finished the line returned to its goods-only role although was occasionally used for diversionary purposes when the West Anglia Main Line was closed south of Cheshunt. Electrification of the line and the reintroduction of passenger services in 1960 saw the line become busy with regular suburban services as part of the Lea Valley Lines. The line became part of London Overground in May 2015.
