British Rail Class 158
The British Rail Class 158 '' Express Sprinter'' is a diesel multiple unit (DMU) passenger train. It is a member of the Sprinter series of regional trains, produced as a replacement for British Rail's first generation of DMUs; of the other members, the Class 159 is almost identical to the Class 158, having been converted from Class 158 to Class 159 in two batches to operate express services from London Waterloo to the West of England. The Class 158 was constructed between 1989 and 1992 by British Rail Engineering Limited (BREL) at its Derby Litchurch Lane Works. The majority were built as two-car sets, some three-car sets were also produced. During September 1990, the first Express Sprinters were operated by ScotRail; the type was promptly introduced to secondary routes across the Midlands, Northern England, Wales and the South West. The Class 158 enabled the replacement of large numbers of elderly DMUs but also several locomotive-hauled trains as well; this was partially a ...

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] |
European Train Control System
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or int ... [...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] |
Railway 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] |
Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...

Hydrokinetic Transmission
A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be the mechanical clutch. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a transmission (mechanics), reduction gear. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque and thus reduces power. Hydraulic systems By far the most common form of torque converter in Automatic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voith
The Voith Group is a German manufacturer of machines for the pulp and paper industry, technical equipment for hydropower plants and drive and braking systems. The family-owned company, which operates worldwide and has its headquarters in Heidenheim an der Brenz, was founded in 1867. Company history Laying the foundations for industrial paper production In 1825, Johann Matthäus Voith took over his father's locksmith's workshop in Heidenheim with five employees, mainly carrying out repairs to water wheels and paper mills. Around 1830 in Heidenheim, there were about 600 people working in 15 factories, mostly textile factories that had been established by wealthy merchants and publishers. The necessary maintenance and repair of the expensive machinery offered a source of income to several workshops, particularly the locksmiths and metalworkers in what was still a small town at the time. In 1830, Johann Matthäus Voith and his workshop were involved in the construction of a pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
