British Rail Class 19
Class 19 is the name given to an experimental railway locomotive that was constructed using a Mark 3 DVT. The locomotive is part of a project funded by the Rail Safety and Standards Board (RSSB) to test the viability of combining hydrostatic transmission with a form of regenerative braking that can reduce engine emissions. Hydrostatic transmissions have been used previously for rail vehicles, but only for slow-speed track maintenance vehicles and similar, not for mainline locomotives. Diesel-hydraulic locomotives instead use a hydrodynamic, i.e. torque converter, transmission. History In 2017, the RSSB announced that it planned to fund the development of an experimental rail vehicle in conjunction with Artemis Intelligent Power, a developmental company specialising in hydraulic machines. The intention of the project was to develop a rail vehicle that could store braking energy, which could then be released during acceleration. It would be powered by diesel engines as the prime m ...

British Rail Engineering Limited
British Rail Engineering Limited (BREL) was the railway systems engineering subsidiary of British Rail. Established in 1970, the maintenance arm was split as British Rail Maintenance Limited in 1987, and the design and building of trains was privatised in 1989, purchased by the Swiss-Swedish conglomerate Asea Brown Boveri (40%), Trafalgar House (40%), and a management-employee buy-out (20%). After ABB became the sole shareholder in September 1992, it was subsumed into ABB Transportation. History BREL was established by the British Railways Board on 1 January 1970 to take over the management of its 14 rolling stock maintenance centres, including Ashford, Crewe, Derby Litchurch Lane, Derby Locomotive, Doncaster, Eastleigh, Glasgow, Horwich, Shildon, Swindon, Wolverton, and York. Ashford Works closed in 1981, Shildon in 1984, and Swindon in 1986. In 1987, Doncaster, Eastleigh, Glasgow, and Wolverton were transferred to BR Maintenance. Not all British Rail rolling stock wa ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel-hydraulic Locomotives Of Great Britain
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quickl ...

Cab (locomotive)
The cab, crew compartment or driver's compartment of a locomotive, or a self-propelled rail vehicle, is the part housing the train driver, fireman or secondman (if any), and the controls necessary for the locomotive or self-propelled rail vehicle's operation. Cab locations On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward or camelback configuration. The cab, or crew or driver's compartment of a diesel or electric locomotive will usually be found either inside a cabin attached to a hood unit or cowl unit locomotive, or forming one of the structural elements of a cab unit locomotive. The former arrangement is now the norm in North America for all types of diesel or electric locomotives. In Europe, most modern locomotives are cab units with two cabs, one at each end. However, the locomotives powering some high speed European trains are normally cab units with one cab, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Hydraulic Accumulator
A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas.Although liquids are generally considered to be practically incompressible, gases may be compressed and this compressed gas is a convenient energy store. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type. Types of accumulators Towers The first accumulators for William Armstrong's hydraulic dock machinery were simple raised water towers. Water was pumped to a tank at the top of these towers by steam pumps. When dock machinery required hydraulic po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Motor
A hydraulic motor is a mechanical actuator that converts hydraulics, hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engine, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery. Conceptually, a hydraulic motor should be interchangeable parts, interchangeable with a hydraulic pump because it performs the opposite function - similar to the way a DC electric motor is theoretically interchangeable with a DC electrical generator. However, many hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pre ...

Hydraulic Pump
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy ( hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Hydrodynamic pumps are more frequent in day-to-day life. Hydrostatic pumps of various types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
