Unsure if its all the time, but the week we were out here, the Bozeman Pass is alittle different in operations than Mullan Pass. Mullan seems mainly 4 helpers mid-train and shove. Over Bozeman sometimes the helpers were cut-in, on the rear, on the headend, or none at all. This practice seems to allow for more flexibility to this 1.8% grade than Mullan probably due to train and size. Here we have a loaded coal train with a MRL unit picked up at Livingston on the headend and helpers on the rear end, doing what they do to fight gravity.
