Tramlink is a light rail tram system serving Croydon and surrounding areas in South London, England. It began operation in May 2000 as Croydon Tramlink, becoming the first tram system in London since 1959. It is owned by London Trams, an arm of Transport for London (TfL), and is operated as a concession by FirstGroup.
The network consists of 39 stops along of track, on a mixture of street track shared with other traffic, dedicated track in public roads, and off-street track consisting of new rights-of-way, former railway lines, and one section of alignment (not track) shared with a third rail electrified Network Rail line.
The network has four lines that coincide in central Croydon, with eastbound termini at Beckenham Junction, Elmers End and New Addington, and a westbound terminus at Wimbledon, where there is an interchange for London Underground. The Tramlink is the third-busiest light rail network in the UK behind the Tyne and Wear Metro and the Docklands Light Railway.
