West Midlands Trains
West Midlands Trains (WMT) is a train operating company in the United Kingdom. It operates passenger trains on the West Midlands franchise between London and the English Midlands under two trade names: West Midlands Railway (WMR) (within the West Midlands region) and London Northwestern Railway (LNR) (outside the region). West Midlands Trains was created as a consortium of three companies, Abellio, JR East, and Mitsui & Co., which joined to bid for the West Midlands franchise; they were amongst the three bids to be shortlisted in April 2016, and were awarded the franchise during August 2017. In addition to the DfT, it is also accountable to the West Midlands Rail Executive for services that operate wholly within the West Midlands region. On 10 December 2017, West Midlands Trains took over operations from the prior operator, London Midland. As per the original terms of the franchise, West Midlands Trains is expected to continue to operate it until March 2026. During October ...

Automatic Warning System
The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. Its operation was later extended to give warnings for; * A colour light signal displaying a double yellow (steady or flashing), single yellow or red aspect * A reduction in permissible speed * A temporary or emergency speed restriction * An automatic barrier crossing locally monitored (ABCL), an automatic open crossing locally monitored (AOCL), or an open crossing (OC). AWS was based on a 1930 system developed by Alfred Ernest Hudd and marketed as the "Strowger-Hudd" system. An earlier contact system, installed on the Great Western Railway since 1906 and known as automatic train control (ATC), was gradually supplanted by AWS within the Western Region of British Railways. Principles of operation Information is conveyed by magnetic fields to the moving train throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airdam
A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Spoilers on the front of a vehicle are often called air dams. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse. The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is a device whose intended design is to generate downforce as air passes around it, not simply disrupt existing airflow patterns. As such, rather than decreasing drag, automotive wings actually increase drag. Operation Since spoiler is a term describing an application, the operation of a spoiler varies depending on the particular effect it is trying to spoil. M ...

British Rail Class 220
The British Rail Class 220 ''Voyager'' is a class of diesel-electric high-speed multiple unit passenger trains built in Belgium by Bombardier Transportation in 2000 and 2001. They were introduced in 2001 to replace the 20-year-old InterCity 125 and almost 40-year-old Class 47-hauled Mark 2 fleets operating on the Cross Country Route. They were initially operated by Virgin CrossCountry and since 2007 have been operated by CrossCountry. Technical details All coaches are equipped with a Cummins QSK19 diesel engine of at 1800 rpm. These power a generator which supplies current to motors driving two axles per coach, with one axle per bogie powered. Voyagers have both air and rheostatic brakes. They are fitted with Dellner couplers, like the Class 222 operated by East Midlands Railway and the Class 390 ''Pendolino'' electric trains used by Avanti West Coast, meaning they can be coupled in rescue/recovery mode (air brake only) in the event of a failure. 220s and 221s can also ...

Bogies
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Chiltern Railways
Chiltern Railways, formally The Chiltern Railway Company Limited, is a British train operating company that has operated the Chiltern Railways franchise since July 1996. Since 2009, it has been a subsidiary of Arriva UK Trains. Chiltern Railways was founded as M40 Trains by a group of ex- British Rail managers backed by John Laing and 3i; in June 1996, it was announced that M40 Trains had been awarded the Chiltern Railways franchise. On 21 July 1996, it took over operations from British Rail. The company promptly commenced the redoubling of the Chiltern Main Line under the ''Evergreen'' initiative and ordered the Class 168 ''Clubman'' diesel multiple units (DMUs) to supplement its ex-British Rail fleet. Following the awarding of a 20-year franchise to Chiltern Railways in August 2000, Evergreen phase 2 works begun to raise line speeds around Beaconsfield, built two new platforms at its London Marylebone terminus. In January 2010, a £250 million upgrade package was agreed fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 171
The British Rail Class 171 ''Turbostar'' is a type of diesel multiple unit (DMU) passenger train built by Bombardier Transportation at Derby Litchurch Lane Works in England. It is identical to the British Rail Class 170, Class 170, except for the replacement of the BSI coupling, BSI coupler with a Dellner coupler. This provision was made to allow emergency joining with British Rail Class 377, Class 377 DC third-rail electric units, which Southern (Govia Thameslink Railway), Southern runs extensively on most lines. The units work on the southern regions of the British railway system, operating services from London Bridge railway station, London Bridge to Uckfield railway station, Uckfield and from Eastbourne railway station, Eastbourne to Ashford International railway station, Ashford International, these routes being unelectrified between Oxted line, Hurst Green Junction and Uckfield and between Marshlink line, Ore and Ashford International, respectively. The fleet is operated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 170
The British Rail Class 170 ''Turbostar'' is a British diesel multiple unit (DMU) passenger train built by Adtranz and later Bombardier Transportation at Derby Litchurch Lane Works. Introduced after privatisation, these trains operate regional as well as long-distance services, and to a lesser extent suburban services. A total of 139 units were built, but some were later converted to and units. These trains are currently in use with West Midlands Trains (formerly London Midland), CrossCountry, East Midlands Railway, Transport for Wales Rail, ScotRail and Northern Trains. Design The class is a development of the design used in the British Rail Class 165 and 166 DMUs known as the ''Networker Turbos'' and built by British Rail Engineering Limited and later ABB Transportation Ltd before that company became part of Bombardier. Notable features shared are the aluminium alloy frame and Voith transmission as well as the general body shape (the cab ends are similar to those of the ...

British Rail Class 168
The Class 168 ''Clubman'' is a British diesel multiple unit (DMU) passenger train used on Chiltern Line services between London Marylebone and the West Midlands. One unit has been converted to hybrid operation as of 2022. Description The trains were built in several batches from 1998. The first batch was classified 168/0 under TOPS and resembled the Class 165 units previously built by BREL York. The Networker-design cab was an interim solution pending the design of a completely new cab for further Turbostar batches. Subsequent builds, subclassed as 168/1 and 168/2, were constructed at the same time as the Class 170 Turbostar and thus are part of the Turbostar family of trains. The first batch of Clubman 168/0 carriages ordered by Chiltern Railways were the first units ordered by any train operating company since the privatisation of the UK industry in 1996. They were delivered as 3-car sets but later lengthened to 4-car sets. Seating A typical Class 168 consists of 2+2 st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derby Litchurch Lane Works
Derby Litchurch Lane Works (formerly Derby Carriage and Wagon Works) is a railway rolling stock factory in Derby, England. It was opened in the 19th century by the Midland Railway. The plant has produced rolling stock under the ownership of the Midland Railway. It is now owned by Alstom. History Midland Railway (1876–1923) Railway building began at Derby Works in 1840, when the North Midland Railway, the Midland Counties Railway and the Birmingham and Derby Railway set up engine sheds as part of their Tri Junct Station. When the three merged in 1844 to form the Midland Railway its first Locomotive and Carriage Superintendent Matthew Kirtley set out to organise their activities and persuaded the directors to build their own rolling stock, rather than buying it in (see Derby Works). By the 1860s the works had expanded to such an extent that he was considering reorganising it and, in 1873, it separated into the Midland Railway Locomotive Works, known locally as "The Loco", and ...

Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
