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.[12]
