When necessary to report the passage of a train prior to fouling or occupying a track, employees must identify the passing train by?

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

Answer: (C)

When you must report the passage of a train before fouling or occupying a track, you need a precise, unambiguous identification of which train is moving. The engine number identifies the exact locomotive (and often the entire consist), while the proper marker display communicates the train’s identity to others observing the train. This combination avoids ambiguity that can arise from train names, directions, or car numbers—names can be shared by different trains, direction only doesn’t tell you which train is coming, and car numbers don’t reliably identify the whole train. So engine number plus the correct marker display is the information you rely on to clearly identify the passing train.
