The Appearance of a fixed signal as viewed from the direction of an approaching train is called what?

• A. Signal Aspect
• B. Signal Indication
• C. Signal Master
• D. Signal Position

Answer: (A)

The signal aspect is the visual appearance of a fixed signal as seen by an approaching train. It describes what the signal looks like—the current color or blade position on the signal head—indicating what the train should do. For example, a red aspect tells the crew to stop, a green aspect tells them to proceed, and a yellow aspect means proceed with caution or be prepared to stop. This concept focuses on what is seen, not the meaning or instruction behind it, which is why it’s distinguished from signal indication. The other terms refer to different ideas: a signal indication is the instruction derived from the appearance, a signal master is the person in charge, and signal position would refer to the physical setup of the signal rather than its displayed state.
