A hot JB Hunt train races around a not-quite-as-hot-but-very-well-powered intermodal. Just behind the photographer, BNSF 6725 will hit the high speed frogs to cross back over to the right-side main, as there is an eastbound also waiting for this (and a following) train to stay on schedule.
The temperature is in the teens, and the wind is blowing robustly, to add to the drama.
