List of current systems for electric rail traction

This is 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.

Key to the tables below

Systems using standard voltages

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

Overhead systems

600 V DC

This voltage is mostly used by older tram systems worldwide but by a few new ones as well.
