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.
