Bonanza Power Plant.
Deseret Power Railway (DPR) E60C electric locomotives DPR-1, DPR-2, and DPR-3 are seen leading the morning empty train away from the Bonanza Power Plant, headed back to the loadout in neighboring Colorado. The power plant is slated for closure by 2030, being replaced with a smaller nuclear plan in the same location, almost certainly spelling the end for the railway much like the Black Mesa & Lake Powell.
