description NRE 3GS21B Genset Overview
The NRE 3GS21B is a diesel-electric switcher locomotive developed by National Railway Equipment Company. It uses a genset design, in which multiple smaller diesel-generator sets supply electrical power to the traction motors instead of relying on one large engine. This arrangement allows the locomotive to use only the engine capacity needed for the current workload. It is intended mainly for low-speed switching and yard operations.
