Which information must be used to identify the passing train when reporting its passage prior to fouling a track?

• A. Engine number and proper marker display
• B. Train name only
• C. Car number
• D. Direction only

Answer: (A)

The key idea is that you must positively identify the moving train before fouling a track by using two specific identifiers: the engine number and the marker display. The engine number is a unique identifier for the locomotive, so it tells you exactly which power unit is in the train. The marker display shows the train’s identification as displayed to the field, such as the train symbol or name shown on the leading unit. Taken together, this combination leaves no ambiguity about which train is passing, which is essential for safe protection of the track. Relying on a train name alone can be misleading since multiple trains can share the same name at different times or routes. Car numbers are part of the train’s makeup but don’t uniquely identify the entire train unit, and direction alone doesn’t tell you which train is involved. Using both the engine number and the marker display ensures the right train is identified before you foul the track.
