List of railway electrification systems#750 V DC

{{Short description|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 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.

Tram electrification systems are listed here.

Key to the tables below

  • Volts: voltage or volt
  • Current:
  • DC = direct current
  • # Hz = frequency in hertz (alternating current (AC))
  • AC supplies are usually single-phase (1φ) except where marked three-phase (3φ).
  • Conductors:
  • overhead line or
  • conductor rail, usually a third 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

Systems using standard voltages

{{see also|Railway electrification system#Voltage|List of tram systems by gauge and electrification}}

Voltages are defined by two standards: BS EN 50163{{sfnp|BS EN 50163|2007}} and IEC 60850.{{sfnp|IEC 60850|2007}}
