DMU :
diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. They may also be referred to as a railcar or railmotor, depending on country. Diesel-powered units may be further classified by their transmission type: diesel-electric (DEMU), diesel-mechanical (DMMU) or diesel-hydraulic (DHMU).
The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or none.
DMUs are usually classified by the method of transmitting motive power to their wheels
