A westbound BNSF unit oil train claws upgrade on Mullan Pass out of Austin, Montana, on July 1, 2020. Mostly hidden in some trees is a Montana Rail Link manned helper set cut in the middle of the train, with the rear green buffer car showing. Directly above that is a lone BNSF DPU locomotive on the rear, that just cleared the grade crossing of the forest road that goes up Mullan Pass out of Austin.
