ELECTRICAL POWER SYSTEMS OF THE WASHINGTON METRORAIL TRANSIT SYSTEM
The electrical systems of the METRO rail system may be divided into two basic functional systems. These are the electric traction system and the support utility electrical system. The traction system converts incoming primary energy to nominal 700 volts direct current for distribution via the contact rail to provide propulsion power for the multiple-unit rail transit cars. The support utility system transforms incoming primary energy for distribution via load centers to station and right-of-way for lighting, mechanical equipment, escalators, elevators, pumps, ventilation, communications and control systems. Both of these facilities are served at primary voltages from the power utility company that serves the jurisdiction that the facility is located in. The METRO power system does not employ sub-transmission between transit facilities at primary voltages.
