Which fixed signal is used to govern the approach to a home signal?

• A. Home Signal
• B. Indication
• C. Distant Signal
• D. Block Signal

Answer: (C)

The distant signal is used to govern the approach to a home signal. It sits ahead of the home signal and conveys the status of the upcoming home signal, giving the engineer time to slow down or stop if needed. If the distant signal shows caution, the train must prepare to stop at the home signal; if it shows clear, the home signal may be ready to show a proceed aspect. This advance warning is what lets you safely enter the block without approaching a red home signal too quickly. The home signal itself governs entry, and a block signal indicates occupancy, but neither provides the advance approach guidance that a distant signal does.
