Railway electrification is the development of powering trains and locomotives using electricity instead of dieselor steam power. The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
The Deseret Power Railroad (reporting mark DPRW), formerly known as the Deseret-Western Railway, is an isolated short line between Colorado and Utah which hauls coal from Deserado Mine to Bonanza Power Plant. It was built in 1983 and opened on January 4, 1984. Electrification is at 50 kv AC overhead wire.
North Jersey Coast Line, New Jersey Transit. Converted in 1978 from Pennsylvania Railroad 11 kV 25 Hz system to the 12.5 kV 25 Hz on the Rahway-Matawan ROW and 12.5 kV 60 Hz electrification extended to Long Branch in 1988. The Matawan-Long Branch voltage converted from 12.5 kV 60 Hz system to the 25 kV 60 Hz in 2002.
Electric locomotives are used for passenger trains on Amtrak 's Northeast Corridor between Washington, DC, and Boston, with a branch to Harrisburg, Pennsylvania, and on some commuter rail lines. Mass transit systems and other electrified commuter lines use electric multiple units, where each car is powered.
Railway electrification as a means of traction emerged at the end of the nineteenth century, although experiments in electric rail have been traced back to the mid-nineteenth century. [1] Thomas Davenport, in Brandon, Vermont, erected a circular model railroad on which ran battery-powered locomotives (or locomotives running on battery-powered ...
Railway engineering is a multi-faceted engineering discipline dealing with the design, construction and operation of all types of rail transport systems. It encompasses a wide range of engineering disciplines, including civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering.
The 2 × 25 kV autotransformer system is a split-phase electric power system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV system. In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail.
A DART 8500 class commuter EMU at Howth Junction railway station, Ireland. 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.
