Alstom Coradia 1000
The Coradia 1000 is a type of Diesel Multiple Unit (DMU) operating in Great Britain and which is part of the Alstom Coradia family of diesel and electric multiple units. There are two types currently in service, the and . , these DMUs are operated by three different train operating companies. Transport for Wales Rail operates the Class 175, and the Class 180 is operated by Grand Central and East Midlands Railway. Design Both of the Coradia 1000 models utilise a diesel-hydraulic powertrain with transmissions being supplied by German manufacturer Voith. The diesel engines are being supplied by American manufacturer Cummins. When both classes were new, they featured hydrodynamic retarders as part of their braking equipment. However, due to the unreliability of this equipment on both the Class 175 and Class 180, they were bypassed with the DMUs now just using their normal air brakes. Both the Class 175 and Class 180 are capable of working in a multiple unit arrangement, with ... [...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] |
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 ...

Hull Trains
Hull Trains is an open-access railway operator in England owned by the multinational transport company FirstGroup. It operates long-distance passenger services between Hull / Beverley and London King's Cross. It has a track-access agreement until December 2032. Hull Trains was originally established in 1999 in the aftermath of the privatisation of British Rail in response to the low volume of trains between Hull and London King's Cross operated by the incumbent franchise. Their initial track-access agreement was granted in December 1999, permitting operations to be launched on 25 September 2000. Hull Trains' track-access agreement has been extended multiple times since commencing operations. Ownership was originally divided between an 80 percent stake held by the train operating company (TOC) GB Railways, while the former British Rail managers Mike Jones and John Nelson held the remainder. A majority stake in the company was acquired by FirstGroup in August 2003, leading to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rail (magazine)
''Rail'' is a British magazine on the subject of current rail transport in Great Britain. It is published every two weeks by Bauer Consumer Media and can be bought from the travel sections of UK newsstands. It is targeted primarily at the enthusiast market, but also covers issues relating to rail transport. ''Rail'' is more than four decades old, and was called ''Rail Enthusiast'' from its launch in 1981 until 1988. It is one of only two railway magazines that increased its circulation. It has roughly the same cover design for several years, with a capitalised italic red ''RAIL'' along the top of the front cover. Editorial policy ''Rail'' is customarily critical of railway institutions, including the Rail Delivery Group, the Office of Rail and Road, as well as, since it assumed greater railway powers, the Department for Transport. ''Rail's'' continuing campaigns include one against advertising and media images showing celebrities and others walking between the rails (an unsafe ...

Its trains called at 528 stations, about a quarter of all stations in the country; of these stations 476 were operated by Northern. On 1 March 2020, Arriva Rail North Limited ceased to operate and all operations were handed to HM Government's Operator of last resort, Operator of Last Resort.

Dynamic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...
