Which item is affixed to the rear of a train to indicate that the train is complete?

• A. Marker
• B. Movable Point Frog
• C. Interlocking Signals
• D. Movement Permit Form D

Answer: (A)

The marker is the item placed on the rear of a train to show the end of the train. This visual cue lets crews and trackside personnel know that all cars are present and accounted for, confirming the train is complete. It also helps following trains and yard operations judge train length and maintain proper clearance, especially in low-visibility conditions. The other options aren’t attached to the train’s rear: a movable point frog is part of a track switch, interlocking signals are trackside devices controlling movements, and a Movement Permit Form D is a written authorization, not a rear-end marker.
