What is a "B-unit"?

A B-unit is a type of railroad car that is used along with a locomotive, but it does not have its own driving controls or engine. Instead, it is a powered car that is usually attached to the front or rear of a train and relies on the engine of the locomotive or another car for power. B-units are often used to increase the power or capacity of a train, providing additional space for passengers or cargo. These units are common in diesel-electric locomotives, where the A-unit contains the driving controls and engine, while the B-unit serves as a supplementary power car.
