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[update] 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
edit- 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

Special or unusual types
editDC, plough collection from conductors in conduit below track

DC, two-wire
edit- Greenwich, England. Previously used by trams when in the vicinity of Greenwich Observatory;[citation needed] separate from trolleybus supply.
- Cincinnati,[citation needed] Ohio, US. Tram (streetcar) system used this arrangement throughout, probably due to legal constraints on ground return currents.[citation needed]
