Railway electrification using 25 kV, 50 Hz AC has become an international standard. There are two main standards that define the voltages of the system: EN 50163:2004+A1:2007 – "Railway applications. Supply voltages of traction systems" [6] IEC 60850 – "Railway Applications.
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating ...
The 2×25 kV autotransformer electrification system includes a third energized parallel negative feeder wire which helps control electromagnetic field propagation. [ 137 ] [ 139 ] The feeder wire is electrified at the same voltage and frequency, but is shifted 180° out of phase so the voltage difference between the contact wire and the feeder ...
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.
The Great Northern Railway (now BNSF Railway) electrified the 2.5-mile (4.0 km) original Cascade Tunnel in 1909, near the summit of Stevens Pass in the Cascade Mountains. This first electrification system with GE-built boxcabs were the only three-phase AC power ever used on North America railroads, see Three-phase AC railway electrification ...
The Class CC 14000 were electric locomotives operated by SNCF in France. They were one of four classes, together with the BB 12000, BB 13000 and CC 14100 classes, that formed an experimental group for studying the practicality of the new French 25 kV 50 Hz AC electrification. [1] It was used in freight service along the Lille – Thionville line.
25 kV AC railway electrification emerged as an economical form of electrification as a result of research and trials in Europe, particularly on French Railways . Indian Railways decided to adopt the 25 kV AC system of electrification as a standard in 1957, with SNCF as their consultant in the early stages, later taken over by the "50 c/s Group".
Beacon Rail. The British Rail Class 88 is a type of mainline mixed traffic electro-diesel locomotive manufactured by Vossloh España/Stadler Rail Valencia for Direct Rail Services (DRS) in the United Kingdom. The locomotive is part of the Stadler Euro Dual family. It is the first dual-mode locomotive in the UK to use the 25 kV AC electrification.
