Diesel-Electric Locomotive
Definition:
A diesel-electric locomotive is a type of train engine that is powered by a diesel engine. This engine generates electricity, which then drives electric motors that move the train. So, instead of directly using the power from the diesel engine to turn the wheels, it first creates electricity, which is used to power the train.
