Which statement defines route setting?

• A. The method of scheduling train timetables.
• B. The procedure for setting signals during normal operation.
• C. A policy for managing passenger fare collection.
• D. The process of selecting paths and signals to guide a train through a route safely.

Answer: (D)

Route setting is selecting a safe path for a train through the network and preparing the controls—points and signals—to guide it along that route. It involves choosing which tracks the train will use, aligning the switches, and ensuring the correct signals are set so the train can proceed without conflict and in line with safety interlocking. In practice, this means the route is planned and protected so the driver receives a clear, consistent sequence of signals along the chosen path, and other movements are prevented from interfering.

Scheduling timetables, on the other hand, deals with when trains run rather than which physical path or signals they use. Setting signals during normal operation describes the real-time signaling action, not the planning of a safe route. Fare collection policies are unrelated to how a route is defined or signalled.
