A 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.
In a diesel-mechanical multiple unit (DMMU) the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-generation British Rail DMUs, but in most applications gears are changed automatically.
In a diesel-hydraulic multiple unit, a hydraulic torque converter, a type of fluid coupling, acts as the transmission medium for the motive power of the diesel engine to turn the wheels. Some units feature a hybrid mix of hydraulic and mechanical transmissions, usually reverting to the latter at higher operating speeds as this decreases engine RPM and noise.
In a diesel-electric multiple unit (DEMU) a diesel engine drives an electrical generator or an alternator which produces electrical energy. The generated current is then fed to electric traction motors on the wheels or bogies in the same way as a conventional diesel electric locomotive.[1]
In modern DEMUs, such as the Bombardier Voyager family, each car is entirely self-contained and has its own engine, generator and electric motors.[1] In older designs, such as the British Rail Class 207, some cars within the consist may be entirely unpowered or only feature electric motors, obtaining electric current from other cars in the consist which have a generator and engine.

R/Raipur Junction -- GUDM/Gudum
Gudum railway station is a small railway station in Balod district, Chhattisgarh. Its code is GUDM. It serves Gudum town. The station consists of 2 platforms. The platform is not well sheltered. It lacks many facilities including water and sanitation.[1]
Some of the important trains that runs from Gudum are :
Raipur - Gudum DEMU
Raipur Junction is the main railway station serving the city of Raipur.It is only few of the railway stations in India which has been given the grade 'A-1' by the Indian Railways and is one of the highest revenue earning railway stations in India. This station is one of the prominent stations on the Howrah-Nagpur-Mumbai line. It is also the originating point of the Raipur-Vizianagarm branch line route.
The Bengal Nagpur Railway was formed in 1887 for the purpose of upgrading the Nagpur Chhattisgarh Railway and then extending it via Bilaspur to Asansol.[1] The Bengal Nagpur Railway main line from Nagpur to Asansol, on the Howrah-Delhi main line, was opened for goods traffic on 1 February 1891.[2]
The 79 km (49 mi) Vizianagaram-Parvatipuram line was opened in 1908-09 and an extension to Salur was built in 1913. The Parvatipuram-Raipur line was completed in 1931.[2]
The Bilaspur-Bhilai section was electrified in 1935-45.[3]
There is a misting system for the passengers at railway station to get the passengers some relief from the heat during summers. Raipur Railway Station is the first station of India to have this technology. Misting system is working from 2013.
