Morphology

diesel-hydraulic = diesel + hydraulic (transparent) = diesel + hydraulic

A straightforward compound of 'diesel' and 'hydraulic' indicating a locomotive powered by a diesel engine with hydraulic transmission; the components directly indicate power source and transmission type.

Etymology

Diesel-hydraulic combines diesel, named after the inventor Rudolf Diesel for the diesel engine, and hydraulic, from hydro meaning 'water' or 'fluid'. So a diesel-hydraulic is a train engine that uses a diesel motor and fluid power to move its wheels.
