The NRE 3GS21C is a low-emissions
diesel
genset locomotive built by
National Railway Equipment (NRE). It is powered by three
Cummins QSK19C
I6 engines with each one developing 700
horsepower (522
kW) and creating a total power output of 2,100
horsepower (1,570
kW). Instead of a single prime mover, the NRE genset locomotive has three engines that each can be turned off or on as power is needed reducing overall
diesel emissions and improving
fuel efficiency.

Mount Vernon shops in

Flexibility
Because the engines are modular, flexibility is obtained:
- If one engine fails, the others can continue at reduced power.
- If a lower axle load is needed, one engine can be left off.
- When reduced power is needed, one or more of the engines can be turned off, saving fuel and wear and tear.
- The
QSK19C engine is common to the four variants of the NRE 3GS21C locomotive.
- The QSK19C engine is widely used for non-railway applications, and spare parts are readily available.
