The mighty Cheyenne Frontier Days special is about to roll into the depot in minutes.

2015's version of the Cheyenne Frontier Days/Denver Post special looked like this, arriving in town with revenue freight right along with it. A pretty fluid operation up there.

For a couple years, UP deployed their E-units with the Centennial for the (then) annual Denver Post Frontier Days special. Here, the train is about 10 minutes from departure north.
