This is something of an interesting looking unit...one that we don't see in Denver too often. This is a 3GS21B, often referred to as a Genset. It was built by National Railway Equipment and uses three low emission Cummins engines. UP has 59 on the roster, and they are primarily used in Texas and California, where emissions standards are more stringent.
