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 Metropolitan line, colloquially known as the Met, is a London Underground line between Aldgate in the City of London and Amersham and Chesham in Buckinghamshire, with branches to Watford in Hertfordshire and Uxbridge in Hillingdon. Printed in magenta on the tube map, the line is 41.4 miles (66.7 km) in length and serves 34 stations. Between Aldgate and Finchley Road, the track is mostly in shallow "cut and cover" tunnels, apart from short sections at Barbican and Farringdon stations. The rest of the line is above ground, with a loading gauge of a similar size to those on main lines. Just under 67 million passenger journeys were made on the line in 2011/12.
Blake Hall is a disused former station on the London Underground in the civil parish of Stanford Rivers, and south from the village of Bobbingworth in Essex. It was latterly on the Central line, between North Weald and Ongar, but was originally served by the Epping to Ongar shuttle service branch line.
North Weald railway station is on the Epping Ongar Railway, a heritage railway, located in North Weald, Essex.
Ongar railway station is a station on the Epping Ongar Railway heritage line, and a former London Underground station in the town of Chipping Ongar, Essex. It was opened in 1865 by the Great Eastern Railway, and became part of London Transport in 1949. Until its closure as such in 1994, it was the easternmost point of the Central line and the eastern buffers remain the point from which all distances on the London Underground are measured.
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.
West Ruislip is a station on Ickenham High Road on the borders of Ickenham and western Ruislip in the London Borough of Hillingdon in Greater London, formerly in Middlesex. It is served by London Underground (LU) and National Rail trains on independent platforms. It is the western terminus of the Central line's West Ruislip branch; Ruislip Gardens is the next Underground station towards central London. The Central line and Chiltern Railways platforms and ticket office hall are managed by LU. The closest station on the Metropolitan and Piccadilly lines is Ickenham, 1.1 miles (1.8 km) from West Ruislip Station.
The Epping Ongar Railway is a heritage railway in south-west Essex, England, run by a small number of paid staff and a team of volunteers. It was the final section of the Great Eastern Railway branch line, later the London Underground's Central line from Loughton via Epping to Ongar, with intermediate stations at North Weald and Blake Hall. The line was closed by London Underground in 1994 and sold in 1998. It reopened between 2004 and 2007 as a preserved railway, offering a volunteer-run Class 117 DMU service between Ongar and Coopersale. A change of ownership in 2007 led to the line being closed for restoration to a heritage steam railway, which opened on 25 May 2012.
Epping is a London Underground station in the market town of Epping in Essex, England. The station serves as the north-eastern terminus of the Central line. Located in Travelcard Zone 6, it is one of eight London Underground stations in the Epping Forest District. The station before Epping is Theydon Bois, which is about three minutes' travelling time away.
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 in 1906–07. By 1907 the District and Metropolitan Railways had electrified the underground sections of their lines.
Electric locomotives were first used on the London Underground when the first deep-level tube line, the City and South London Railway (C&SLR), was opened in 1890. The first underground railways in London, the Metropolitan Railway (MR) and the District Railway (DR), used specially built steam locomotives to haul their trains through shallow tunnels which had many ventilation openings to allow steam and smoke to clear from the tunnels. It was impractical to use steam locomotives in the small unvented tubular tunnels of the deep-level lines, and the only options were rope haulage or electric locomotives.
The New Works Programme of 1935–1940 was the major investment programme delivered by the London Passenger Transport Board (LPTB), commonly known as London Transport, which had been created in 1933 to coordinate underground train, tram, trolleybus and bus services in the capital and the surrounding areas. The programme was to develop many aspects of the public transport services run by the LPTB and the suburban rail services of the Great Western Railway (GWR) and London and North Eastern Railway (LNER). The investment was largely backed by government assistance as well as by the issuing of financial bonds and was estimated to cost £42,286,000 in 1936.
The Central London Railway Stock were electric multiple units composed of trailers that had been converted from carriages designed to be hauled by electric locomotives with new motor cars. The Central London Railway opened in 1900 with electric locomotives hauling wooden carriages, but the heavy locomotives caused vibrations that could be felt in the buildings above the route. It was found that conversion to electric multiple units solved the problem, so new motor cars were bought and replaced all the locomotives by June 1903. Trains normally ran with six-cars, four trailers and two motor-cars. Some trailers were equipped with control equipment to allow trains to be formed with three cars.
The Hainault Loop, originally opened as the Fairlop Loop, is a 6.5-mile (10.5 km) branch line of the Great Eastern Railway (GER). It once connected Woodford on the Ongar branch to Ilford on the Main Line, with an eastward connection for goods, excursions and stock transfers to Seven Kings. The loop opened to freight on 20 April 1903 and to passengers on 1 May 1903. In 1923, the GER was "grouped" into the London & North Eastern Railway (LNER), who provided passenger services until December 1947. After this date, the route was electrified for London Underground services from both the Woodford and Leytonstone directions, the link to Ilford closed, and today it forms the greater part of the Hainault Loop on the Central line, having been served by Tube trains since 1948.
The transport system now known as the London Underground began in 1863 with the Metropolitan Railway, the world's first underground railway. Over the next forty years, the early sub-surface lines reached out from the urban centre of the capital into the surrounding rural margins, leading to the development of new commuter suburbs. At the turn of the nineteenth century, new technology—including electric locomotives and improvements to the tunnelling shield—enabled new companies to construct a series of "tube" lines deeper underground. Initially rivals, the tube railway companies began to co-operate in advertising and through shared branding, eventually consolidating under the single ownership of the Underground Electric Railways Company of London (UERL), with lines stretching across London.
The Chesham branch is a single-track railway branch line in Buckinghamshire, England, owned and operated by the London Underground. It runs from a junction at Chalfont & Latimer station on the Metropolitan line for 3.89 miles (6.26 km) northwest to Chesham. The line was built as part of Edward Watkin's scheme to turn his Metropolitan Railway (MR) into a direct rail route between London and Manchester, and it was envisaged initially that a station outside Chesham would be an intermediate stop on a through route running north to connect with the London and North Western Railway (LNWR). Deteriorating relations between the MR and LNWR led to the MR instead expanding to the northwest via Aylesbury, and the scheme to connect with the LNWR was abandoned. By this time much of the land needed for the section of line as far as Chesham had been bought. As Chesham was at the time the only significant town near the MR's new route, it was decided to build the route only as far as Chesham, and to complete the connection with the LNWR at a future date if it proved desirable. Local residents were unhappy at the proposed station site outside Chesham, and a public subscription raised the necessary additional funds to extend the railway into the centre of the town. The Chesham branch opened in 1889.
London's Metropolitan Railway (MR) amalgamated with other underground railways, tramway companies and bus operators on 1 July 1933, to form the London Passenger Transport Board (LPTB); the MR became the Board's Metropolitan line.
Ruislip depot is a London Underground traction maintenance depot on the Central line, and is situated between the stations of Ruislip Gardens and West Ruislip in the London Borough of Hillingdon. The depot is accessible from both ends, and was built for the Central Line extensions under the 1935-1940 New Works Programme. It was nearly completed by 1939, when the outbreak of the Second World War prevented further work. It was used as a factory for anti-aircraft guns during the war, and was finally opened in 1948. The main car shed has 16 tracks, and there is also a three-track car cleaning shed.
Hainault depot is a traction maintenance depot on the London Underground Central line, between Hainault and Grange Hill stations, now in the London Borough of Redbridge, England. Until boundary changes in 1998, part of the depot was in Epping Forest District. Construction began in 1939, but was delayed by the onset of the Second World War, and was not completed until 1948. It has stabled three generations of trains, Standard stock, 1962 stock and 1992 stock. It has also housed trains of the experimental 1960 stock, both when it was conventionally controlled and during trials of Automatic Train Operation (ATO) in preparation for the construction of the Victoria line. Some of the 1967 stock destined for the Victoria line was also stabled at the depot while its ATO equipment was tested and commissioned on the Woodford to Hainault Branch.
Lillie Bridge Depot is a historic English traction maintenance depot on the London Underground Piccadilly and District lines, situated between West Brompton and West Kensington stations in the London Borough of Hammersmith and Fulham. It is accessed from the District line tracks between Earl's Court and West Kensington or between Earl's Court and Kensington (Olympia).
