AUXILIARY POWER UNIT (APU) is an alternative source of power for a diesel locomotive and is generally installed in short hood of ALCo’s.

In Short, APU consist of a small diesel engine connected to an alternator and a small compressor.

When the APU is switched on, this power source prevents the batteries from getting discharged and maintains the required air pressure in the air brake system.

Also it reduces the fuel consumption. The V16 engine of a locomotive usually consumes 25 litres of fuel per hour, while APU consumes only 3 litres of fuel per hour, which results in massive reduction in fuel consumption.
