It is a self-contained system with its own small diesel engine coupled to low capacity compressor and alternator to maintain main reservoir pressure, charge battery, operate driver cabin HVAC system and other small loads as per customer requirement. The main engine is started only when the locomotive is actually required for movement or traction.
