It is powered by three Cummins QSK19C I6 engines with each one developing {{convert|700|hp|lk=on|sigfig=3}} and creating a total power output of {{convert|2100|hp|lk=on|sigfig=3}}. Having multiple engines instead of a single prime mover, a design referred to as a "Genset," reduces overall diesel emissions and improves fuel efficiency.[1] More than 150 of the 3GS21B Genset locomotives have been produced to date, with the majority of these units being manufactured at NREC's Mount Vernon shops in Southern Illinois.[2] In addition, three road slug models have also been produced.
