City and South London RailwayThe City and South London Railway (C&SLR) was the first successful deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotives—an experimental technology at the time—was chosen instead. When opened in 1890, the line had six stations and ran for in a pair of tunnels between the City of London and Stockwell, passing under the River Thames.
Stockwell tube stationStockwell is a London Underground station in Stockwell in the London Borough of Lambeth. It is located on the Northern line between Oval and Clapham North stations, and on the Victoria line between Brixton and Vauxhall stations. It is in Travelcard Zone 2. The station opened on 4 November 1890 as the southern terminus of the City and South London Railway, the first successful deep-level tube in London. The Victoria interchange opened on 23 July 1971 when that line was extended south from Victoria towards Brixton.
Tube mapThe Tube map (sometimes called the London Underground map or diagram) is a schematic transport map of the lines, stations and services of the London Underground, known colloquially as "the Tube", hence the map's name. The first schematic Tube map was designed by Harry Beck in 1931. Since then, it has been expanded to include more of London's public transport systems, including the Docklands Light Railway, London Overground, the Elizabeth line, Tramlink, the London Cable Car and Thameslink.
District lineThe District line is a London Underground line running from in the east and Edgware Road in the west to in west London, where it splits into multiple branches. One branch runs to in south-west London and a short branch, with a limited service, only runs for one stop to . The main route continues west from Earl's Court to after which it divides again into two western branches, to Richmond and . Printed in green on the Tube map, the line serves 60 stations (more than any other Underground line) over .
London UndergroundThe London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, opening on 10 January 1863 as the world's first underground passenger railway. It is now part of the Circle, District, Hammersmith & City and Metropolitan lines.
