Transport in London

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.

Other rail services are either franchised to train operating companies by the Department for Transport (DfT) or, like Eurostar and Heathrow Express, operated on an open-access basis. TfL also controls most major roads in London, but not minor roads. In addition, there are several independent airports serving London, including Heathrow, the busiest airport in Europe.

Early public transport in London began with horse-drawn omnibus services in 1829, which were gradually replaced by the first motor omnibuses in 1902. Over the years the private companies which began these services amalgamated with the London General Omnibus Company (LGOC) to form a unified bus service. The Underground Electric Railways Company of London, also formed in 1902, unified the pioneering underground railway companies which built the London Underground; in 1912 the Underground Group took over the LGOC and in 1913 it also absorbed the London tramway companies. The Underground Group became part of the new London Passenger Transport Board (LPTB) on 1 July 1933, which also took over the Metropolitan Railway. Underground trains, Green Line coaches, trolleybuses and trams then began to operate as London Transport, although the name 'General' continued to be seen on buses and their timetables for a few months longer.

The London Transport name continued in use until 2000 (2003 on the Underground), although the political management of transport services changed several times. The LPTB oversaw transport from 1933 to 1947 until it was re-organised as the London Transport Executive (1948 to 1962). Responsibility for London Transport was subsequently taken over to the London Transport Board (1963 to 1969), the Greater London Council (1970 to 1984) and London Regional Transport (1984 to 2000/2003).

Following the privatisation of London bus services in 1986, bus services were spun off to a separate operation based on competitive tendering, London Buses. On 3 July 2000, as part of the formation of the new Greater London Authority, responsibility for most of London Transport was taken over by a new transport authority, Transport for London (TfL), which is the publicly owned transport corporation for the London region now.

However, because of the continuing controversy over public-private partnerships in connection with London Underground maintenance, the new GLA led by Mayor Ken Livingstone was not permitted to take control of the Underground until the PPP contracts had been signed. In the event, London Regional Transport continued in existence as the owner of London Underground Ltd until July 2003. London Regional Transport was wound up on 15 July.

TfL operates three different railway systems across London. The largest is the London Underground, a rapid transit system operating on sub-surface lines and in deep-level "tube" lines. TfL also operates the Docklands Light Railway (DLR), an automated light rail system in the east of the city, and the Tramlink system.
