The NRE 3GS21B is a low-emissions diesel road switcher locomotive built by National Railway Equipment. 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). At least 16 [1] [2] 3GS21C genset locomotives have been produced to date at NREC's Mount Vernon shops in Southern Illinois.[3]
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 engine.
- The QSK19C engines from Cummins is widely used for non-railway applications, and spare parts are readily available. [4]
