DC Traction Power Supply and Distribution System for MARTA’s Armour Yard Rail Services Facility

The best place to see all aspects of a heavy rail transit traction power supply and distribution system in action is at a storage and maintenance Yard located adjacent to the main line. This paper presents an overview of the DC Traction Power System (TPS) for Metropolitan Atlanta Rapid Transit Authority’s Armour Yard Rail Services Facility. This state-of-the-art facility is constructed for MARTA’s newly increased fleet size to accommodate rail car storage, train wash, interior car cleaning, service, inspection, maintenance, and component overhaul.
