Electric Multiple Units
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ex ...

Liverpool Overhead Railway Carriage, Museum Of Liverpool-2
Liverpool is a city and metropolitan borough in Merseyside, England. With a population of in 2019, it is the 10th largest English district by population and its metropolitan area is the fifth largest in the United Kingdom, with a population of 2.24 million. On the eastern side of the Mersey Estuary, Liverpool historically lay within the ancient hundred of West Derby in the county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of the newly-created Lancashire County Council in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shinkansen
The , colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is operated by five Japan Railways Group companies. Over the Shinkansen's 50-plus-year history, carrying over 10 billion passengers, there has been not a single passenger fatality or injury on board due to derailments or collisions. Starting with the Tokaido Shinkansen () in 1964, the network has expanded to currently consist of of lines with maximum speeds of , of Mini-Shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network presently links most major cities on the islands of Honshu and Kyushu, and Hakodate on northern island of Hokkaido, with an extension to Sapporo under const ...

Frecciarossa 1000
The Frecciarossa 1000, is a high-speed train operated by Italian state railway operator Trenitalia. It was co-developed as a joint venture between Italian rail manufacturer Hitachi Rail Italy (initially AnsaldoBreda) and multinational conglomerate Alstom (initially Bombardier Transportation). Both design and production work were divided between the two partner companies. Design work on the train began in 2008, with considerable design work performed by Bertone. It was heavily based on existing products, including Bombardier's Zefiro and AnsaldoBreda's V250 trains. The design was modified in order to conform with the requirements of the Trenitalia tender. In 2010, the ETR 1000 was selected and a total of 50 trainsets were ordered to meet Trenitalia's needs. Upon the public unveiling of the first example of the type, it was hailed as being the fastest train to reach series production in Europe at that time. History and design Early work During the mid 2000s, Italian state r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pendolino
Pendolino (from Italian ''pendolo'' "pendulum", and ''-ino,'' a diminutive suffix) is an Italian family of tilting trains used in Italy, Spain, Germany, Poland, Portugal, Slovenia, Finland, Russia, the Czech Republic, Slovakia, the UK, the US, Switzerland, China and Greece. Based on the design of the Italian ETR 401 (itself being based on British Rail innovations), it was further developed and manufactured by Fiat Ferroviaria, which was taken over by Alstom in 2000. The idea of a tilting train became popular in the 1960s and 1970s when various rail operators, impressed by the high-speed rail services being introduced in France and Japan, wondered how they could similarly speed up travel without building a dedicated parallel rail network (as those two countries were doing). By tilting, the train could go around curves designed for slower trains at higher speeds without causing undue discomfort to passengers. Current use Italy In Italy, various possibilities were explored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Unit
A twin unit or twinset is a set of two railroad cars or locomotives which are permanently coupled and treated as if they were a single unit. A twinset of cars or coaches can also be called a twin car. In US passenger railroad parlance, twin units are also known as married pairs. On passenger railroads, light rail, and monorail services, married pairs may have machinery necessary for full operation of the cars split between them. Items that are typically shared include transformers, motor controllers, dynamic braking grids, cabs, current collectors, batteries, and air compressors. This provides significant savings in both cost of equipment and weight, which increases performance and decreases energy consumption. The cost of operating such a pair may be slightly higher when the extra car in such a pair is not needed to meet level-of-service demands at a particular time.

Jumper Cable
Jumper cables are electric cables to connect two rail or road vehicles. Rail Jumper cables are between the locomotive, the railroad cars and the cab car or the driving van trailer on push-pull trains for multiple-unit train control and the transmission of lower voltage electricity (head end power). Road Jumper cables are electrical cables between the road tractor and a semi-trailer or a full trailer or the electrical cables between an automobile and any trailer.

Passenger Car (rail)
A passenger railroad car or passenger car ( United States), also called a passenger carriage, passenger coach ( United Kingdom and International Union of Railways), or passenger bogie ( India) is a railroad car that is designed to carry passengers. The term ''passenger car'' can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars. The first passenger cars were built in the early 1800s with the advent of the first railroads, and were small and little more than converted freight cars. Early passenger cars were constructed from wood; in the 1900s construction shifted to steel and later aluminum for improved strength. Passenger cars have increased greatly in size from their earliest versions, with modern bi-level passenger cars capable of carrying over 100 passengers. Amenities for passengers have also improved over time, with developments such as lighting, heating, and air conditioning added for improved passen ...

Control Car
A control car, cab car (North America), control trailer, or driving trailer (UK and Ireland) is a non-powered rail vehicle from which a train can be operated. As dedicated vehicles or regular passenger cars, they have one or two driver compartments with all the controls and gauges required to remotely operate the locomotive, including exterior locomotive equipment such as horns, bells, ploughs, and lights. They also have communications and safety systems such as GSM-R or European Train Control System (ETCS). Control cars enable push-pull operation when located on the end of a train opposite its locomotive by allowing the train to reverse direction at a terminus without moving the locomotive or turning the train around. Control cars can carry passengers, baggage, and mail, and may, when used together with diesel locomotives, contain an engine-generator set to provide head-end power (HEP). They can also be used with a power car or a railcar. European railways have used con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collector ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented ...
