The Watford Joint Tube Stock was built for the service to Watford along both the Bakerloo tube and the London North Western Railway. As a result, the cars were owned by both the Underground and the London North Western Railway. To be able to operate on both lines, the car floors were 4+1⁄2 inches (110mm) higher than other tube cars. This was a compromise height between the platform heights on the two lines.
The cars were ordered in 1914, but construction was delayed by World War I. As a result, the first cars were not delivered until early 1920.
A total of 72 cars were built by Metropolitan Carriage and Wagon: 36 motor cars, 24 trailers, and 12 driving trailers. They were formed into six-car trains, and for the first time a motor car was used in the middle of the train. For this to happen, there had to be a passageway by the switch compartment as required by the Board of Trade.
These cars were built with hinged doors to the passenger compartments, an arrangement that caused delays during station stops, as each door had to be manually checked before the train departed.[1]
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 Railway was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital's financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at Paddington, Euston, and King's Cross to the City. The first section was built beneath the New Road using cut-and-cover between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield, near the City. It opened to the public on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives, the world's first passenger-carrying designated underground railway.
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 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 LNWR electric units were ordered by the London and North Western Railway for its suburban services in London. The first cars, made with Siemens equipment, arrived in 1914, and these were followed by two larger batches of units with Oerlikon equipment. The trains were formed into 3-car units, with first and third class accommodation in open saloons. Following the 1923 grouping and absorption of the line into the London, Midland and Scottish Railway (LMS), similar LMS electric units, but with accommodation in compartments, were purchased to run with the Oerlikon units in 1926 and 1932. The trains were all withdrawn by 1960.
The T Stock was a series of electric trains originally built in various batches by Metropolitan-Vickers and the Birmingham Railway Carriage and Wagon Company for the Metropolitan Railway in 1927–31 for use on electric services from Baker Street and the City to Watford and Rickmansworth, though rarely some worked on the Uxbridge branch.
The London Underground A60 and A62 Stock, commonly referred to as A Stock, was a type of sub-surface rolling stock which operated on the Metropolitan line of the London Underground from 12 June 1961 to 26 September 2012, and on the East London line from 1977 until 22 December 2007, when it closed to be converted into London Overground.
An electric multiple unit (EMU) is an electric self-powered train, capable of operating in multiple with other EMUs and without the need for a locomotive; these are typically passenger trains with accommodation in every vehicle and a driving position at each end. The term can also be used to describe a train that is a permanent formation with a non-driving power car, such as the Advanced Passenger Train. As of December 2010, two-thirds of the passenger carriages in Great Britain are formed in EMUs.
The British Rail Class 501 electric multiple units were built in 1955/56 for use on the former LNWR/LMS suburban electric network of the London Midland Region. A total of 57 three-car units were built.
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.
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.
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 London Underground F Stock was built in 1920 and 1921 for the District Railway by the Metropolitan Carriage, Wagon and Finance Company. They were partly funded by the government as part of an initiative to help British industry recover from World War I. One hundred steel-bodied cars were built: 40 driving motors, 12 control trailers and 48 trailers with the first train entering service on 23 December 1920. The cars were built with manually-operated sliding doors.
The 1920 Tube Stock consisted of forty cars built by Cammell Laird in Nottingham, England. These cars were the first new tube cars to be built with air operated doors. The batch consisted of twenty trailer and twenty control trailer cars, which were formed into six-car trains by the addition of twenty French motor cars built in 1906 and modified for air-door operation. They initially ran on the Piccadilly tube, but in 1930 were considered to be drab, compared to new stock being delivered at the time. The motor cars were therefore replaced by Standard Stock units, built in 1927, and the 1920 cars were refurbished. They were transferred to the Bakerloo line in 1932, and continued to operate until 1938.
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 1906 Stock, also known as "Gate Stock", was built for the Yerkes tube lines, Baker Street and Waterloo Railway (BS&WR), Great Northern, Piccadilly and Brompton Railway (GNP&BR), and Charing Cross, Euston and Hampstead Railway (CCE&HR).
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.
Metropolitan Railway electric multiple units were used on London's Metropolitan Railway after the lines were electrified in the early 20th century.
District Railway electric multiple units were used on London's Metropolitan District Railway after the lines were electrified in the early 20th century.
