Union Pacific's Salt Lake City, UT to Denver, CO manifest rambles east toward a crew change at Helper, Utah. The 92 car train has a three unit mid train helper cut in that shoved the heavy MRONY from Castilla to Soldier Summit. The helper would soon be cut out of the train at the dispatcher controled switches at West Helper. Utah Railway's Martin Yard is visible in the distance along a ledge on the west side of the valley.
