Which term is defined as 'The signal appearance, which conveys an indication as viewed from the approaching train or from the cab display'?

• A. Siding
• B. Signal Aspect
• C. Signal Indication
• D. Station

Answer: (B)

Signal aspect is the signal’s visual presentation that you see as you approach, which conveys what action is allowed. It’s the actual appearance of the signal—colors and positions of lights or signals seen from the cab or the front of the train—that tells you what to do next. The meaning that goes with that appearance (the instruction you must follow) is the signal indication, but the term in this context is about what you visually perceive—the aspect. For example, a red aspect means stop, a green aspect means proceed, and a yellow aspect means proceed with caution or be prepared to stop depending on the system. Siding and Station refer to locations or track types, not the signal’s appearance.
