Superb winter sunshine on stunning Soldier Summit in Utah's Wasatch Mountains. Heavy coal drags charging up-grade with 6 unit sets of Utah Railway helpers, or a six unit set of Rio Grande tunnel motors, plus BNSF on trackage rights, all in gorgous December sunshine. The second half of the program is Union Pacific in Weber and Echo Canyons with a variety of traffic, power is everything UP has, including brand new AC6000ís. Superb light and lots of action.
