A Train is defined as which of the following?

A Train is defined as which of the following?

• A. An engine or more than one engine coupled, with or without cars, displaying a marker.
• B. A single automobile.
• C. A track car.
• D. A yard engine.

Answer: (D)

In NORAC, the key idea is recognizing which locomotive unit is considered a train for rule purposes. A yard engine is a locomotive assigned to yard switching duties, moving cars within a yard. Because it operates as a self-contained moving unit under locomotive authority in the yard, it fits the way NORAC classifies a train for yard operations. The other options describe broader or different concepts (a general engine with or without cars, a single automobile, or a track car) that don’t align with how a yard locomotive used for switching is treated under these rules. So, the yard engine is the best match for the definition in this context.
