Traction current converter plants are either decentralized (where one plant directly supplies the overhead lines or third rail of the traction system, with no feed into a traction current distribution network) or centralized (for the supply of the traction power network, usually in addition to the direct supply of the overhead lines or third ...
A traction network or traction power network is an electricity grid for the supply of electrified rail networks. The installation of a separate traction network generally is done only if the railway in question uses alternating current (AC) with a frequency lower than that of the national grid, such as in Germany , Austria and Switzerland .
All 25 Hz power on the ex-Reading system is generated at the Wayne Junction static converter plant. This plant was built between 1985 and 1990 and consists of three 15 MVA solid-state, cycloconverter-based modules. The system was built by ASEA and is similar technically to the converter later installed at Amtrak's Jericho Park converter.
Amtrak Avelia Liberty trainset operating under the 25 Hz traction power system near Claymont, Delaware. Amtrak's 25 Hz traction power system is a traction power network for the southern portion of the Northeast Corridor (NEC), the Keystone Corridor, and several branch lines between New York City and Washington D.C.
This is a list of the power supply systems that are, or have been, used for railway electrification. Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors.
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. Supply voltages of traction systems" [7]

A traction power station is a power station that produces only traction current, that is, electric current used for railways, trams, trolleybuses or other conveyances. Pure traction power stations are rare and there are many more power stations that generate current for other purposes, such as standard three-phase alternating current (AC), in addition to traction current.
