Union Pacific LEGACY 3GS21B Genset Switcher #2701
The first railroad to pioneer the use of the Genset switcher, Union rolled out this environmentally-friendly motive power locomotive in 2007. Built by the National Railway Equipment Company, this engine emits 80% fewer pollutants into the air, uses far less fuel than similar switchers, and meets the government’s most stringent regulatory noise level requirements.
What allows this Genset to be so environmentally friendly is its ingenious construction. There are three separate 700-h.p. generator sets (or Gen-sets) underneath the loco hood, each towered by its own exhaust stack. These engines can operate independently, in a pair, or all three at once depending on how much power the locomotive needs at any given time. They also utilize an ingenious “sleep time” technology: When idling, only one of three engines stays active, and when sitting for too long all three engines shut down automatically at a pre-programmed time. Each engine also restarts automatically during shutdowns to circulate coolants that protect the engines.
