Abstract: A diesel-engined rail shunting locomotive is provided which combines a very high level of noise insulation with excellent accessibility to the engine and associated apparatus. The locomotive is adapted for remote control by radio, and also has at least one cab for the operator. The engine and associated apparatus are covered by a noise insulating rectangular box-shaped hood which is liftable as a single unit by means of power-operated lifting means provided on the locomotive. The lifting means may be screw jacks located in the four corners of the hood. The cab has an end wall slightly spaced from adjacent the end wall of the hood, to simplify construction and improve sound insulation.
