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.[1] At least 27[2][3] 3GS21C genset locomotives have been produced to date at NRE's Mount Vernon shops in Southern Illinois.[4]

Flexibility

[edit]

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.[13]
