Which system provides power for LRVs and their auxiliaries?

• A. Switch Stand
• B. Timetable
• C. Traction Power System
• D. Tail Track

Answer: (C)

The system that provides power for LRVs and their auxiliaries is the Traction Power System. This electrical network delivers the energy from substations to the streetcar, powering both the traction motors that move the vehicle and the onboard auxiliary systems like lights, HVAC, and control electronics. Substations convert utility AC to the DC voltage used by the rail system, and electricity is carried along overhead lines or a third rail to the vehicle, with the rails serving as the return path. In short, the traction power system is the source of all propulsion and onboard electrical power along the line. The others don’t fit because a switch stand controls track switches, a timetable is schedule information, and a tail track is a storage/reversing track; none of these supply electrical power to the LRVs.
