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 ...

Turbo-diesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. * ...

British Rail Class 165
The British Rail Class 165 ''Networker Turbo'' is a fleet of suburban diesel multiple-unit passenger trains (DMUs), originally specified by and built for the British Rail Thames and Chiltern Division of Network SouthEast. They were built by BREL York Works between 1990 and 1992. An express version was subsequently built in the form of the Class 166 ''Networker Turbo Express'' trains. Both classes are now sometimes referred to as "Networker Turbos", a name derived some three years later for the project that resulted in the visually similar and EMUs. The class is still in service, now operated by Great Western Railway and by Chiltern Railways. When operated originally by Network SouthEast, along with that operator's Class 166 trains, the Paddington suburban units were initially known as ''Thames Turbos'', while the units operated on the Marylebone suburban network were known as ''Chiltern Turbos''.

London Midland
London Midland was a train operating company in England which operated the West Midlands franchise between 11 November 2007 and 10 December 2017. It was owned by the British transport group Govia. London Midland was created as a result of Govia being awarded the West Midlands franchise on 22 June 2007. This franchise had emerged out of a reorganisation conducted by the Department for Transport, which had combined elements of the Silverlink and Central Trains operations together. London Midland had various commitments to fulfil during the franchise period, including the procurement of at least 37 new multiple units, the introduction of a semi-fast service between London and Crewe, and to invest at least £11.5m into stations. Early rolling stock orders totalled 66 new trains, including two Class 139 ''Parry People Movers'', 12 two-car and 15 three-car Class 172 ''Turbostars'' and 37 four-car Class 350/2 ''Desiros''. Further orders and reorganisations of rolling stock would occ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Sprinter (British Rail)
The Sprinter is a family of diesel multiple unit trains in use on the British railway system. They were built in the 1980s and early-1990s by British Rail Engineering Limited (BREL), Metro-Cammell and Leyland. Most have Cummins engines with Voith hydraulic transmissions, although 47 Class 158 units have Perkins engines instead. Sprinters can be seen operating in almost every part of Great Britain, from rural branch lines to commuter expresses into major cities. Originally British Rail coined the "Sprinter" name for the units, mainly to promote the superior acceleration capabilities of the units compared with the first-generation DMUs they replaced. Advertisements such as "The Sprinters are coming" were locally advertised in newspapers when these trains were scheduled to be introduced. Great play was also made of, in many cases, reduced journey times. Background By the beginning of the 1980s, British Rail (BR) operated a large fleet of first generation DMUs, which had been c ...

Pacer (British Rail)
Pacer was the operational name of the British Rail Classes 140, 141, 142, 143 and 144 diesel multiple unit railbuses, built between 1980 and 1987. They were inexpensively developed using a passenger body based on the Leyland National bus on top of a chassis based on the HSFV1 research vehicle. The railbuses were intended as a short-term solution to a shortage of rolling stock, with a lifespan of no more than 20 years. As modernised replacements were lacking, the Pacer fleet remained in service on some lines until 2021 37 years after their introduction in 1984. All Pacer trains were scheduled to be retired by the end of 2019 as the Rail Vehicle Accessibility Regulations require that all public passenger trains must be accessible to disabled people by 2020 however the Pacer units were given dispensation until the end of 2020. Only one Pacer (the modernised 144e) met this requirement, and the remainder were therefore planned to be withdrawn by that date. Furthermore, a decision ...

BSI Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Protection & Warning System
The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia. The British Rail Safety and Standards Board's definition is: The purpose of TPWS is to stop a train by automatically initiating a brake demand, where TPWS track equipment is fitted, if the train has: *passed a signal at danger without authority *approached a signal at danger too fast *approached a reduction in permissible speed too fast *approached buffer stops too fast. TPWS is not designed to prevent SPADs but to mitigate the consequences of a SPAD, by preventing a train that has had a SPAD from reaching a conflict point after the signal. A standard installation consists of an on-track transmitter adjacent to a signal, activated when the signal is at danger. A train that passes the signal will have its emergency brake activated. If the train is travelling at speed, this may be too late to stop it before the point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
