Which term designates the engine or engines coupled, with or without cars, that display markers?

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

Answer: (B)

In railroad terms, a train is the moving unit formed by the engines (one or more) coupled together, with or without cars, that display marker lights. Marker lights identify the train to signalmen and other trains, so the unit that carries those markers—whether it’s just engines or engines with cars—is described as a train. The other phrases aren’t standard terms used to name this moving unit, so they don’t capture the same concept of the locomotive(s) functioning as a single, marker-displaying train.
