Which term is defined as an engine or more than one engine coupled, with or without cars, displaying markers?

• A. Train of Superior Right
• B. Train
• C. Superior Train
• D. Train of Superior Direction

Answer: (B)

In railroad terminology, a train is defined as one or more locomotives coupled together, with or without cars, that are displaying markers. The presence of markers shows the train’s identity to signals and dispatch, and the unit is treated as a single moving entity even if there are no cars attached. That’s why a lone engine with markers still fits the definition—it's the same moving unit recognized as a train. The other phrases aren’t standard terms used to describe this moving unit in railroad practice; an engine refers to the power unit itself, and phrases like “train of superior right/direction” aren’t recognized terms.
