After disappearing for a while, Union Pacific GS14B Y2005 has returned to Dolores Yard in Carson, California. This engine was built by National Railway Equipment from Southern Pacific MP15DC 2690, and features a pair of Cummins 700hp truck engines are under the hoods. The unit appears to have been repainted, as the lettering is a bit different than it was a few years ago (click HERE for an older view).
