This a list of the voltages used or have been used for tramway and railway electrification systems.

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

Key to the tables below

• Volts: voltage

• Current:
  • DC = direct current
  • xx Hz = frequency in hertz (alternating current (AC))
    • AC supplies are single-phase, except where marked three-phase

• 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, affected by ice, snow and leaves
      • side contact: newer, safer, less affected by ice, snow and leaves
      • bottom contact: newer, safer, least affected by ice, snow and leaves

Systems using Standard Voltages

Voltages are defined by two standards: BS EN 50163 and IEC 60850
