Morphology

power + train

Given 'power' (energy) and 'train' (a gearset transmitting motion), the compound 'power train' is compositionally the set of components that transmit power; its meaning is directly derivable from the constituents. Although technical, the construction is literal and cross-linguistically paralleled, so a B1 learner who knows both words would generally infer the MWE's meaning.

Etymology

Power train comes from the image of power followed by a train of linked parts, like a line of wagons pulled in a row. It names the engine plus the connected gears and shafts that carry power to the wheels, so it means the system that makes a vehicle move.
