The electrified=* key is used to specify the form of electrification system used on railway, tram and trolley bus systems.

How to map

Add it on railway=* ways for electrified railways and on highway=* ways for trolley bus systems.

Values

Some electrification methods broadly in use are presented in the following table.

Key Value Element Comment Photo
electrified contact_line Used for tracks electrified with Overhead Contact Line (OCL) / Overhead Contact System (OCS) / Overhead Line Equipment (OLE)
electrified rail Used for tracks electrified with a 3rd rail system, with one additional rail on insulators, using shoe pickup by the train, and traction return via the running rail(s)
electrified 4th_rail Used for tracks electrified with a 4th rail system, with two additional rails on insulators and two shoe pickup by the train, and traction current returning via one of the insulated rails
electrified ground-level_power_supply Ground-level power supply, also known as surface current collection and Alimentation Par le Sol (APS)
electrified yes This tag is to be used when the system of electrification is unknown. Mappers should use electrified=contact_line, rail, 4th_rail, or ground-level_power_supply where they are able to identify the system by use of aerial imagery or other means.
electrified no Not electrified

Additional tags

The following keys are related to the electrical system in use. Consider adding the following data if known.

  • frequency - The frequency with which the line is electrified, specified in hertz. For example frequency=0 (for DC), 16.7, 50, 60, etc.
  • voltage - The nominal voltage of the system, specified in volts. For example 600, 750, 1000, 1500, 3000, 15000, 25000.
