Which term describes the composition and identity of a train's cars and locomotives?

Explanation:
Describing the composition and identity of a train’s cars and locomotives is handled by the term consist. The consist lists which locomotives are used, which cars are included, the order of those units, and any special equipment or reporting details for the train. This information is essential for dispatching, operation, and signaling, because it tells you how the train is assembled and how power, braking, and control should be applied. The other terms refer to different ideas: a block is a signaling segment on the tracks, a coupler is the device that physically connects cars, and emergency denotes a safety condition or urgent braking event.
