List of railway electrification systems

From Wikipedia, the free encyclopedia
A list of the different systems used on electric railways

This is a list of the power supply systems that are, or have been, used forrailway electrification.

Note that the voltages are nominal and vary depending on load and distance from the substation.

As of 2023[update], many trams and trains use on-board solid-state electronics to convert these supplies to runthree-phase AC traction motors.

Tram electrification systems are listedhere.

Key to the tables below

[edit]
  • Volts:voltage orvolt
  • Current:
  • Conductors:
    • overhead line or
    • conductor rail, usually athird rail to one side of the running rails. Conductor rail can be:
      • top contact: oldest, least safe, most affected by ice, snow, rain and leaves. Protection boards are installed on most top contact systems, which increases safety and reduces these affections.
      • side contact: newer, safer, less affected by ice, snow, rain and leaves
      • bottom contact: newest, safest, least affected by ice, snow, rain and leaves
  • Red background indicates voltages no longer in use on the indicated location

Systems using standard voltages

[edit]
See also:Railway electrification system § Voltage, andList of tram systems by gauge and electrification

Voltages are defined by two standards: BS EN 50163[1] and IEC 60850.[2]

Overhead systems
