List of current systems for electric rail traction


List of current systems for electric rail traction

This a list of the power supply systems that are, or have been, used for tramway and railway electrification systems.

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

Many modern trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC induction motors.

Contents

Key to the tables below

  • 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 [1] and IEC 60850[2]

Special or unusual types

DC, plough collection from conductors in conduit below track

DC, one ground-level conductor

  • Wolverhampton Corporation Tramways, England. (stud contact) (1902–1921)

DC, two ground-level conductors

DC, two-wire

  • Greenwich, England. Previously used by trams when in the vicinity of Greenwich Observatory; separate from trolley-bus supply.
  • Cincinnati, Ohio, USA. Tram (streetcar) system used this arrangement throughout, probably due to legal constraints on ground return currents.
  • Havana and Guanabacoa, Cuba. Tram (streetcar) systems in both cities used this arrangement.

DC, power from running rails

DC, four-rail
