Which term refers to a signal at a fixed location that affects the movements of a train?

• A. Fouling Point
• B. Fixed Signal
• C. Fouling Time
• D. Electrically Locked Switch

Answer: (B)

A fixed signal is a signal placed at a fixed location along the track that governs train movements. It remains at a set spot and provides authority to proceed, proceed with restrictions, or stop, based on the signal aspect. This distinguishes it from other railroad terms: fouling point refers to where tracks or blocks become unsafe due to an occupancy situation, fouling time is the period a track is considered fouled, and an electrically locked switch describes a switch that cannot be moved unless the interlocking permits it. So the signal at a fixed location that affects train movements is a fixed signal.
