The Union Pacific did things on a big scale, and nothing exemplified this better than the locomotives it used on Sherman Hill. Here, you’ll journey back to the days when 4-8-8-4 Big Boys and 4-6-6-4 Challengers pounded the rails of this mighty incline as they stormed westward out of Wyoming. You’ll also enjoy the rare 4-12-2s, the 800 Class 4-8-4s, the massive Veranda turbines and a bevy of UP passenger trains with pristine steam and diesels at the helm. Color, 54 minutes. #0RV6521
