Marker is:

Marker is:

• A. A reflector, flag, or highly visible marking device, in red-orange-amber color range, affixed to the rear of a train to indicate that the train is complete.
• B. A marker placed at the front of the train for timing.
• C. A device attached to track circuits for warning.
• D. A light used to indicate a loaded train.

Answer: (A)

Markers are rear-end indicators used to show the end of a train. They’re reflectors, flags, or other highly visible devices in the red-orange-amber color range, affixed to the rear of the train to indicate that the train is complete. This visibility lets following trains and trackside personnel know where the train ends, helping maintain safe spacing and clear operations during movement, coupling, or switching. They are not placed at the front for timing, not attached to track circuits for warning, and not a light that signals the train’s load status.
