A southbound Z train rounds the curve at Apex, just north of Las Vegas.
Five motors (and a DPU out of sight) lug about 40 cars or so of this eastbound through Sloan and then into Las Vegas Valley.
UP 7630 & 5108 lead WB stacks. UP 5340 was in DPU mode.
Under a slight cloud shadow, GEVO 7630 brings up the rear of a westbound stack train a few miles west of the Continental Divide.
