Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or 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. In 1881, the first permanent railway ...
Electrification was installed from Sunnyside Yard in Queens, through New York Penn Station to Manhattan Transfer station in New Jersey. A 675 V DC third rail (Top Contact) system was used. [18] Electrification was later changed to 11 kV 25 Hz overhead catenary
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line . [ 1 ]
Railway electrification in Great Britain. Acton Central station is a changeover point from 750 V DC third rail, to 25 kV AC overhead electrification, on the North London Line. Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails.
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.
A third rail supplied power to the world's first electric underground railway, the City & South London Railway, which opened in 1890 (now part of the Northern line of the London Underground). In 1893, the world's second third-rail powered city railway opened in Britain, the Liverpool Overhead Railway (closed 1956 and
The East Coast Main Line in the United Kingdom is electrified using 25 kV 50 Hz overhead lines. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s.
Three-phase AC railway electrification. Train using a multiphase electrification system on the Petit train de la Rhune, France. Three-phase AC railway electrification was used in Italy, Switzerland and the United States in the early twentieth century. Italy was the major user, from 1901 until 1976, although lines through two tunnels also used ...
