is a type of railway locomotive in which the power source is a diesel engine.

It is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as battery or supercapacitor.

It provides air which is blown over the traction motors to keep them cool during periods of heavy work.

It provides AC power for lighting, heating, air conditioning, dining facilities, etc. on the train.

It has to be filtered to remove dust and other impurities and its flow regulated by temperature, both inside and outside the locomotive.

The output from the main alternator is AC but it can be used in a locomotive with either DC or AC traction motors.

It usually includes a maintenance management system of some sort which can be used to download data to a portable or hand-held computer

The diesel engine needs a battery to start it and to provide electrical power for lights and controls when the engine is switched off and the alternator is not running.

The main output from the diesel engine is transmitted by the drive shaft to the alternators at one end and the radiator fans and compressor at the other end.

rovided on the axles to give the final drive A modern AC motor with air blowing can provide up to 1,000 hp.

It is used to change the direction of the drive upwards.

It is often referred to as a bogie or bogey, is a structural component of a train that carries and supports the weight of the train's carriages or wagons.

A hydraulic clutch (consists of a case filled with oil, a rotating disc with curved blades driven by the engine and another connected to the road wheels).

It is responsible for generating compressed air used for various functions throughout the train.

It is responsible for transmitting power from the train's propulsion system to the radiator fan, ensuring that the cooling system operates effectively under all conditions.

Contained compressed air at high pressure is required for the train braking and some other systems on the locomotive.
