Traction Power System:

Traction Power System:

• A. The substations, feeder cable, contact wires, switch gear, and other equipment interfacing with public utilities or other power sources to provide power for the movement of LRVs and their auxiliary systems.
• B. The timetable and signals for controlling trains.
• C. The devices used for passenger information displays.
• D. The tail track and mainline.

Answer: (A)

The Traction Power System is the network that delivers electrical power to LRVs and their onboard systems. It includes substations that convert utility power to the required traction voltage, feeder cables that carry that power along the line, contact wires (or the overhead supply) that deliver power to the vehicles, and switch gear and other equipment that manage and route power and interface with public utilities or other power sources to ensure a reliable supply for movement and auxiliaries. The other options refer to aspects outside power delivery: the timetable and signals govern train movement control, passenger information displays provide rider information, and the tail track plus mainline describe track layout and routing, not the electrical power system.
