A Union Pacific potash train passes by A.L. Gilbert Company Livestock Feed Plant in Keyes Ca.

UP 7783 & 6804 lead a seemingly endless string of westbound empties.

In a scene repeated many times a day, UP 7783 leads another westbound autorack train across the Kansas City Terminal tracks that stretch across town.

An eastbound intermodal runs through Altamont pass as the California poppies start to bloom and the hills turn green.

The transition between UP's locomotive fleet and the passenger fleet will now be a little smoother thanks to the freshly rebuilt UPP 2066 power car with a hunchback on one end.
