Distant Signal is used to govern the approach of a train to which signal?

• A. A movable signal indicating occupancy.
• B. A signal used to govern speed on a main track.
• C. A fixed signal used to govern the approach of a train to a home signal.
• D. A red indicator at night only.

Answer: (C)

Distant signals provide a warning about the aspect of the next signal ahead, giving the engineer time to slow down or stop as needed. They are fixed signals placed before a home signal to govern the approach to that fixed signal, which controls entry into a block or interlocking. So the distant signal’s purpose is to guide how you approach a fixed signal that is the home signal. It’s not about occupancy indicators, nor a separate speed-signaling device for the main track, and it isn’t simply a red indicator used only at night.
