Wimbledon station in the context of "Govia Thameslink Railway"

Tramlink, previously Croydon Tramlink and currently branded as London Trams, is a light rail tram system serving Croydon and surrounding areas in South London, England. It is the first operational tram system serving the London region since 1952. Tramlink is presently managed by London Trams, a public body part of Transport for London (TfL), and has been operated by FirstGroup since 2017. It is one of two light rail networks in Greater London, the other being the Docklands Light Railway. Tramlink is the fourth-busiest light rail network in the UK behind the Docklands Light Railway, Manchester Metrolink and Tyne and Wear Metro.

Studies for the delivery of a modern-day tram system in Croydon began in the 1960s and detailed planning was performed in the 1980s. Approval of the scheme was received in 1990 and, following a competitive tender process, construction and initial operation of the tramway was undertaken by Tramtrack Croydon (TC) via a 99-year Private Finance Initiative (PFI) contract. The official opening of Tramlink took place on 10 May 2000; by the end of the year three routes were operational. The network consists of 39 stops along 28 km (17 mi) 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 right-of-way where the Tramlink track runs parallel to a third rail-electrified Network Rail line. The network's lines coincide in central Croydon, with eastern termini at Beckenham Junction, Elmers End and New Addington, and a western terminus at Wimbledon, where there is an interchange for London Underground.

The District line is a London Underground line running from Upminster in the east and Edgware Road in northwestern Central London to Earl's Court in west London, where it splits into multiple branches. One branch runs to Wimbledon in south-west London and a short branch, with a limited service, only runs for one stop to Kensington (Olympia). The main route continues west from Earl's Court to Turnham Green after which it divides again into two western branches, to Richmond and Ealing Broadway.

Printed in green on the Tube map, the line serves 60 stations (more than any other Underground line) over 40 miles (64 km). It is the only Underground line to use a bridge to traverse the River Thames, crossing on both the Wimbledon and Richmond branches. The track and stations between Barking and Aldgate East are shared with the Hammersmith & City line, and between Tower Hill and Gloucester Road and on the Edgware Road branch they are shared with the Circle line. Some of the stations between South Kensington and Ealing Common are shared with the Piccadilly line. Unlike London's deep-level lines, the railway tunnels are just below the surface, and the trains are of a similar size to those on British main lines.
