The Central line is a London Underground line that runs through central London, from Epping, Essex, in the north-east to Ealing Broadway and West Ruislip in west London. Printed in red on the Tube map, the line serves 49 stations over 46 miles (74 km), making it the longest line on the Underground. It is one of only two lines on the Underground network to cross the Greater London boundary, the other being the Metropolitan line. One of London's deep-level railways, Central line trains are smaller than those on British main lines.
The Bakerloo line is a London Underground line that runs from Harrow & Wealdstone in suburban north-west London to Elephant & Castle in south London, via the West End. Printed in brown on the Tube map, it serves 25 stations, 15 of which are underground, over 23.2 kilometres (14.4 mi). It runs partly on the surface and partly through deep-level tube tunnels.
The 1959 Tube Stock was a type of London Underground tube train constructed in the late 1950s. They were intended for use on the Piccadilly line, but also saw use on several other tube lines. It was the first production tube stock to have unpainted aluminium alloy bodywork.
London Underground rolling stock includes the electric multiple-unit trains used on the London Underground. These come in two sizes, smaller deep-level tube trains and larger sub-surface trains of a similar size to those on British main lines, both running on standard gauge tracks. New trains are designed for the maximum number of standing passengers and for speed of access to the cars.
The London Underground 1938 Stock was a London Underground tube stock design. A total of 1,121 cars were built by Metro-Cammell and Birmingham RC&W. An additional 173 cars were added to the fleet by the end of 1953, comprising 91 new builds, 76 conversions from Pre-1938 Tube Stock or 1935 Tube Stock, and six unconverted cars of 1935 Tube Stock, and the stock was used on the London Underground until 1988. During their long lives they worked on the Bakerloo, Northern, Piccadilly, East London, Central, and Northern City lines. Ten sets were refurbished and ran on the Isle of Wight as Class 483, making them the oldest passenger rolling stock operating timetabled services on the National Rail network at the time of their withdrawal in January 2021. The trains represented a major technical advance, as all the electrical equipment was located under the floor for the first time. All previous tube stock had large equipment compartments behind the driving cabs in motor cars, which reduced the space available for passengers by about a third.
The London Underground 1992 Stock is a type of rolling stock used on the Central and Waterloo & City lines of the London Underground. A total of 85 eight-car trains were built for the Central line and 5 four-car trains were built for the Waterloo & City line.
The Standard Stock title was applied to a variety of Tube stock built between 1923 and 1934, all of which shared the same basic characteristics, but with some detailed differences. This design is sometimes referred to as 1923 Tube Stock, 1923 Stock, or Pre 1938 Stock. Most of the Standard Stock was built to replace the first generation of "Gate Stock" Tube trains or to provide additional trains for extensions built in the 1920s and early 1930s. Standard Stock cars consisted of motor cars, with a driver's cab, behind which was a "switch compartment" occupying approximately one-third of the length of the car, plus trailer cars and "control trailers", with a driving cab but no motor. All were equipped with air operated sliding doors. The guard's door on the earlier trains was a manually operated, inward-opening hinged door.
The history of the London Underground began in the 19th century with the construction of the Metropolitan Railway, the world's first underground railway. The Metropolitan Railway, which opened in 1863 using gas-lit wooden carriages hauled by steam locomotives, worked with the District Railway to complete London's Circle line in 1884. Both railways expanded, the Metropolitan eventually extending as far as Verney Junction in Buckinghamshire, more than 50 miles (80 km) from Baker Street and the centre of London. The first deep-level tube line, the City and South London Railway, opened in 1890 with electric trains. This was followed by the Waterloo & City Railway in 1898, the Central London Railway in 1900, and the Great Northern and City Railway in 1904. The Underground Electric Railways Company of London (UERL) was established in 1902 to fund the electrification of the District Railway and to complete and operate three tube lines, the Baker Street and Waterloo Railway, the Charing Cross, Euston and Hampstead Railway and the Great Northern, Piccadilly and Brompton Railway, which opened during 1906–1907. By 1907, the District and Metropolitan Railways had electrified the underground sections of their lines.
The London Underground 1962 Stock was a type of London Underground tube train built for use on the Central line. They were used on the Central line between 1962 and 1995, with some later being transferred to the Northern line where they were used until 1999.
The London Underground 1983 Stock was a class of electric multiple unit built by Metro-Cammell for use on London Underground's Jubilee line.
The London Underground 1972 Stock is a type of rolling stock used on the London Underground. The 1972 Stock was originally ordered to make up the shortfall in trains on the Northern line's 1959 Tube Stock fleet, but is currently used on the Bakerloo line. Following the withdrawal of the British Rail Class 483 EMUs in 2021, the 1972 Stock are now the oldest EMUs in passenger service in the United Kingdom. A total of 63 seven-car trains were built in two separate batches.
The London Underground C69 and C77 Stock, commonly referred to as the C Stock, was a type of sub-surface rolling stock used on the Circle, District and Hammersmith & City lines of the London Underground between 1970 and 2014. They were replaced by the S7 Stock.
The London Underground 1967 Stock was a type of deep-level train that operated on the Victoria line of the London Underground from the line's opening on 1 September 1968 until 30 June 2011. It was also used on the Central line between Woodford and Hainault between 21 February 1968 and 1984, as the same automatic train operation (ATO) system was used on both lines.
The London Underground 1996 Stock is a type of rolling stock used on the Jubilee line of the London Underground. The trains were built by GEC Alsthom-Metro-Cammell and entered service in 1997. They are similar to the 1995 Stock used on the Northern line.
The London Underground 1995 Stock is a type of rolling stock used on the Northern line of the London Underground. A total of 106 six-car trains were built, entering service between June 1998 and April 2001, replacing the 1959 Stock, 1962 Stock and 1972 Stock. They are very similar to the 1996 Stock used on the Jubilee line.
Rolling stock used on the London Underground and its constituent companies has been classified using a number of schemes. This page explains the principal systems for the rolling stock of the Central London Railway (CLR), the Underground Electric Railways Company of London (UERL), the District Railway (DR) and the Metropolitan Railway (MR). For information about individual classes of locomotives and other rolling stock, see London Underground rolling stock.
The railway infrastructure of the London Underground includes 11 lines, with 272 stations. There are two types of line on the London Underground: services that run on the sub-surface network just below the surface using larger trains, and the deep-level tube lines, that are mostly self-contained and use smaller trains. Most of the lines emerge on the surface outside the Central London area.
The London Underground 2024 Stock, known as the New Tube for London (NTfL) during development, is a London Underground train being built by Siemens Mobility at its facilities in Goole, United Kingdom and Vienna, Austria. It is part of the Siemens Inspiro family of metro and rapid-transport trains.
Although the railway network in Great Britain has some of the smallest loading gauges in the world, the vast bulk of it is still capable of operating full sized vehicles. However, British Rail, together with its predecessors and successors have, on occasion, been required to operate passenger trains to an even smaller loading gauge and have, as a consequence, obtained rolling stock identical to that of the "deep tube" lines of London Underground; these are lines built using the tunneling shield method, that were, by necessity, smaller than those lines built using the cut-and-cover method. In 1892, a Parliamentary Committee headed by James Stansfeld recommended that such lines be in tunnels with a minimum diameter of 11 ft 6in. Two routes operated by British Rail required the use of such deep-tube rolling stock, the Waterloo & City Line in London, and the Island Line on the Isle of Wight.
The Four Lines Modernisation (4LM) is a series of projects by Transport for London (TfL) to modernise and upgrade the sub-surface lines of the London Underground: the Circle, District, Hammersmith & City and Metropolitan lines. The upgrades entail new rolling stock, new signalling and new track and drainage.
