A few miles east of Hanna, WY and the UP 844 is shooting out a bit of black smoke. The diesel on the train is UP 7813. It is an ES44AC delivered to UP a little over a year earlier. It's dynamic brakes are used when proceeding down a grade so the train doesn't have to rely entirely on air brakes. It also serves as a back up (for power) in the event the UP 844 become unable to continue on.
