EspañolELECTRIC MULTIPLE UNIT
(Redirected from Electrical multiple unit)
An 'Electric Multiple Unit' or 'EMU' is a multiple unit train consisting of many carriages using electricity as the motive power.
The cars that form a complete EMU set can usually be separated by function into four types : Power Car, Motor Car, Driving Car, and Trailer Car. Each car can have more than one function, such as a Motor-Driving Car or Power-Driving Car.
★ A Power Car carries the necessary equipment to draw power from the electrified infrastructure, such as shoes for third rail systems and pantograph for overhead lines systems, and transformers.
★ Motor Cars carry the traction motor to move the train.
★ Driving Cars are similar to a cab car, containing a driver's cab for controlling the train. An EMU consist usually has two driving cars, with one at each end of the train.
★ Trailer Cars are any car that carry no traction or power related equipments, and is similar to a passenger car in a locomotive hauled train.
Some of the more famous Electric Multiple Units in the world are high speed trains: the Shinkansen in Japan, the TGV in France, and ICE 3 in Germany.
EMUs are also popular on commuter and suburban rail networks around the world due to their fast acceleration, pollution free operation and quietness. Being quieter than DMU and Locomotive drawn trains, EMUs can operate later at night and more frequently without disturbing residents living near the railway lines. In addition tunnel design for EMU trains is simpler as provisions do not need to be made for diesel exhaust fumes.
