The information conveyed by the aspect of a signal is called what?

• A. Signal Indication
• B. Signal Aspect
• C. Signal Color
• D. Signal Plate

Answer: (A)

The information conveyed by a signal’s aspect is called the signal indication. In signaling, the aspect is the visible display (the color and position you see). The indication is the meaning behind that display—the instruction you must follow, such as stop, proceed with caution, or proceed. So while the aspect is the display itself, the indication is the message it communicates to the train crew. The other terms describe different parts: color is just the hue shown, and plate is a physical marker, not the information conveyed.
