Transport for London in the context of "London Underground"

The Greater London Authority (GLA), colloquially known by the metonym City Hall, is the devolved regional governance body of Greater London, England. It consists of two political branches: an executive Mayor (currently Sadiq Khan) and the 25-member London Assembly, which serves as a means of checks and balances on the Mayor. The authority was established in 2000, following a local referendum, and derives most of its powers from the Greater London Authority Act 1999 and the Greater London Authority Act 2007.

It is a strategic regional authority, with powers over transport, policing, economic development, and fire and emergency planning. Three functional bodies —Transport for London, the Mayor's Office for Policing and Crime, and the London Fire Commissioner— are responsible for delivery of services in these areas. The planning policies of the Mayor of London are detailed in a statutory London Plan which is regularly updated and published.

London has an extensive and developed transport network which includes both public and private services. Journeys made on its integrated transport network account for 37% of London's journeys while private services accounted for 36% of journeys, walking 24% and cycling 2%, according to numbers from 2017. London's public transport network serves as the central hub for the United Kingdom in rail, air and road transport.

Public transport services are dominated by the city's executive agency for transport, Transport for London (TfL). TfL controls the majority of public transport, including the Underground, Buses, Tramlink, the Docklands Light Railway, London River Services, Elizabeth line and the London Overground.

The London Transport Museum (LTM) is a transport museum based in Covent Garden, London. The museum predominantly hosts exhibits relating to the heritage of London's transport, as well as conserving and explaining the history of it. The majority of the museum's exhibits originated in the collections of London Transport, but, since the creation of Transport for London (TfL) in 2000, the remit of the museum has expanded to cover all aspects of transport in the city and in some instances beyond.

The museum operates from two sites within London. The main site in Covent Garden uses the name of its parent institution, and is open to the public every day, excluding over Christmas, having reopened in 2007 after a two-year refurbishment. The other site, located in Acton, is the London Transport Museum Depot and is principally a storage site of historic artefacts that is open to the public on scheduled visitor days throughout the year.

London Buses is the subsidiary of Transport for London (TfL) that manages most bus services in London, England. It was formed following the Greater London Authority Act 1999 that transferred control of London Regional Transport (LRT) bus services to TfL, controlled by the Mayor of London.

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.

London River Services Limited is a division of Transport for London (TfL), which manages passenger transport - leisure-oriented tourist services and commuter services - along the River Thames in and around London. It does not own or operate any boats itself, except those on the Woolwich Ferry, but licences the services of operators.

The Thames had been used as a common means of transport in London for centuries, but use died off in the early 1900s, as transportation was enhanced (and river traffic somewhat blocked) with a proliferation of bridges and tunnels. With these numerous north–south crossings of the Thames, which is generally no more than 300 m (980 ft) wide as it flows through central London, the revival of river boat services in London therefore mostly travel east or west along the Thames rather than across it; the only major cross-river ferry services can be found further downstream where the river is much wider, and there are far fewer bridge or tunnel crossings.

London Overground (also known simply as the Overground) is a suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, it now serves a large part of Greater London as well as Hertfordshire, with 113 stations on the six lines that make up the network.

The Overground forms part of the United Kingdom's National Rail network but it is under the concession control and branding of Transport for London (TfL). Operation has been contracted to Arriva Rail London since 2016. TfL previously assigned orange as a mode-specific colour for the Overground in branding and publicity including the roundel, on the Tube map, trains and stations.

A transit district or transit authority is a government agency or a public-benefit corporation created for the purpose of providing public transportation within a specific region.

A transit district may operate bus, rail or other types of transport including ferry service, or may operate other facilities. In some cases, the transit district may be part of a larger organization such as a state Department of Transportation.
