London Underground 1967 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. 316 cars (39.5 train sets) were built by Metro-Cammell, and subsequently refurbished at Rosyth. Withdrawn cars of Mk I 1972 Stock were later moved into the 1967 stock fleet in the 1990s, creating a fleet of forty-three 1967 stock trains. As they did not feature ATO, they were used only as non-driving cars, positioned in the middle of trains rather than at the ends. By the beginning of their retirement in 2010, the 1967 stock had achieved a mean distance between failures of over . Each complete train consisted of two four-car units coupled together. The operator started it by simultaneously pressing two buttons in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metro-Cammell
Metro-Cammell, formally the Metropolitan Cammell Carriage and Wagon Company (MCCW), was an English manufacturer of railway carriages, locomotives and railway wagons, based in Saltley, and subsequently Washwood Heath, in Birmingham. Purchased by GEC Alsthom in May 1989, the Washwood Heath factory was closed in 2005. The company designed and built trains for the railways in the United Kingdom and overseas, including the Mass Transit Railway of Hong Kong, Kowloon–Canton Railway (now East Rail line), the Channel Tunnel, and the Tyne and Wear Metro, and locomotives for Malaysia's Keretapi Tanah Melayu. Diesel and electric locomotives were manufactured for South African Railways, Nyasaland Railways, Malawi, Nigeria, Trans-Zambezi Railway and Pakistan. DMUs were supplied to Jamaica Railway Corporation and the National Railways of Mexico. The vast majority of London Underground rolling stock manufactured in mid-20th century was produced by the company. It also designed and built ...

Fourth Rail
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Walthamstow Central Station
Walthamstow Central is a London Underground and London Overground interchange station in the town of Walthamstow in the London Borough of Waltham Forest, north-east London. It is the northern terminus of the Victoria line following Blackhorse Road and is the second of five stations on the Chingford branch of the Lea Valley lines operated by London Overground since 2015, from London Liverpool Street between and . The two lines have separate platforms at different levels. The station is in Travelcard Zone 3. It linked to station on the Gospel Oak to Barking line by a broad footpath, Ray Dudley Way. Walthamstow Central is the closest tube station to Walthamstow Market, the longest outdoor market in Europe. History The station was opened by the Great Eastern Railway (GER) as Hoe Street in 1870 when a line was opened from to a temporary station called Shern Hall Street which was east of the Hoe Street station. The line to London, that the Chingford branch uses today was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground 1959 Stock
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. Construction The 1959 Stock was built by Metro-Cammell in Birmingham and were closely based on the prototype aluminium alloy bodied 1956 Stock. As with the 1956 stock, the DM cars seated 42, the NDM and T cars seated 40 each. They were initially built for service on the Piccadilly line, where they first entered service on 14 December 1959. It operated at various times on the Northern, Bakerloo, Central and Piccadilly lines. The units had a long career, with a few examples remaining in service until 2000, three years beyond their intended withdrawal date. The 1959 Stock entered service on the Piccadilly line, but most units were drafted to the Central line because that line's "Standard stock" was becoming v ...

London Underground 1962 Stock
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. Construction The 1962 Stock was built by Metro-Cammell and the BR Workshops in Derby for use on the Central line. Each unit consisted of four cars; two outer driving motors (DM), an intermediate trailer (T), and an intermediate non-driving motor (NDM), formed DM + T + NDM + DM. A train usually consisted of two units working in multiple forming an eight-car train. Most 1962 stock units were 4 cars long, although an extra 3-car unit was also ordered; this vehicle lacked an NDM carriage and was numbered 1751. This unit was ordered specifically for the Aldwych shuttle until it was given a fourth car in 1989 and entered service on the Central Line. The 1962 Stock was ordered as a matter of urgency to replace the Standard Stock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground Standard Stock
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. 1922 Stock prototype cars For evaluation purposes, in anticipation of the large number of cars that were to be built over the next several years, six experimen ...

London Underground 1960 Stock
The London Underground 1960 Stock was a class of electric multiple unit for the London Underground Central line. Twelve motor cars were supplied by Cravens, and pairs were made up to four cars by the addition of two converted standard stock trailers. A production run of 338 motor cars was shelved, due to the time needed to assess the new features and the cost of converting the trailer cars. Some of the pre-1938 trailers were later replaced by 1938 stock trailers. The trains were used as a test-bed for automatic train operation, where control signals were picked up from the running rails, and all control of the moving train, apart from the initial command to start when leaving a station, was managed by a "black box" controller. The Woodford to Hainault section of the Central line was used for these tests, in preparation for the introduction of the system on the Victoria line when it opened. In 1986, three trains were converted back for manual operation, and a 3-car unit worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northumberland Park Depot
The Victoria line is a London Underground line that runs between in south London and in the north-east, via the West End. It is printed in light blue on the Tube map and is one of the only two lines on the network to run completely underground, the other being the Waterloo & City line. The line was constructed in the 1960s and was the first entirely new Underground line in London for 50 years. It was designed to reduce congestion on other lines, particularly the Piccadilly line and the branch of the Northern line. The first section, from Walthamstow Central to , opened in September 1968 and an extension to followed in December. The line was completed to Victoria station in March 1969 and was opened by Queen Elizabeth II who rode a train from Green Park to Victoria. The southern extension to Brixton opened in 1971, and Pimlico station was added in 1972. The Victoria line is operated using automatic train operation, but all trains have drivers.

Mean Distance Between Failures
Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system. For example, an automobile's failure rate in its fifth year of service may be many times greater than its failure rate during its first year of service. One does not expect to replace an exhaust pipe, overhaul the brakes, or have major transmission problems in a new vehicle. In practice, the mean time between failures (MTBF, 1/λ) is often reported instead of the failure rate. This is valid and useful if the failure rate may be assumed constant – often used for complex units / systems, electronics – and is a general agreement in some reliability standards (Military and Aerospace). It does in this case ''only'' relate to the flat region of the bat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Underground 1972 Stock
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 nowadays used on the Bakerloo line. Following the withdrawal of the British Rail Class 483 EMUs in 2021, these trains are the oldest EMUs in passenger service in Britain. A total of 63 seven-car trains were built in two separate batches. Construction A total of 252 cars were built by Metro-Cammell at Washwood Heath. In the early 1970s, the 1938 Tube stock on the Bakerloo and Northern line was life-expired and due for replacement. Tentative designs for a new Northern line fleet were abandoned when the go-ahead was given for the Piccadilly line to be extended to Heathrow Airport. That required a totally new fleet of trains to replace the 1959 stock then in use. The plan was made to transfer the 1959 trains to the Northern, to allow the worst of the 1938 stock ther ...
