Union Pacific B23-7 #121 leads the Cache Valley Local north out of Logan, Utah. Today's duties will include picking up 11 box car loads of metal cans at Smithfield and setting out two loaded covered hoppers of plastic pellets at Presto Plastics in Lewiston. The UP 121 was built by GE as the Missouri Pacific 4621 in October 1978. By 2007, it was used as a core for rebuilding into an RP20GE Gen-Set as the UPY 2653.
