NRE 3GS21B
Template:Short description Script error: No such module "Infobox".Script error: No such module "Check for unknown parameters".
The NRE 3GS21B is a low-emissions diesel genset locomotive built by National Railway Equipment (NRE). Instead of a single prime mover, the NRE genset locomotive is powered by three separate Script error: No such module "convert". Cummins QSK19C engines providing a total power output of Script error: No such module "convert".. Each engine could be individually started or shut off depending on how much power is needed, reducing overall diesel emissions and improving 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 NRE's Mount Vernon shops in Southern Illinois.[2] In addition, three road slug models have also been produced. The main difference between this and the NRE 3GS21C is that these units are on B-B (four wheel) trucks and the others are on C-C (six wheel) trucks.
Flexibility
Because the engines are modular, flexibility is obtained:
- If one engine fails, the others can continue at reduced power.
- 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 also widely used for non-railway applications, and spare parts are readily available.[3]
