Transport for London (TfL) is a local government body responsible for most of the transport network in London, United Kingdom.
TfL is the successor organisation of the London Passenger Transport Board, which was established in 1933, and several other bodies in the intervening years. Since the current organisation's creation in 2000 as part of the Greater London Authority (GLA), TfL has been responsible for operating multiple urban rail networks, including the London Underground and Docklands Light Railway, as well as London's buses, taxis, principal road routes, cycling provision, trams, and river services. It does not control all National Rail services in London, although it is responsible for London Overground and Elizabeth line services. The underlying services are provided by a mixture of wholly owned subsidiary companies (principally London Underground), by private-sector franchisees (the remaining rail services, trams and most buses) and by licencees (some buses, taxis and river services). Fares are controlled by TfL, rail services fares calculated using numbered zones across the capital.
