I was on my way home from Missoula, and I came across a BNSF manifest around Jens on I90. I decided that Elliston was a good place to setup as it is the start of the grade on Mullan pass for East bounds. I got a pleasant surprise while waiting for the manifest when I heard a horn from behind me. I swung my camera around in time to catch a loaded BNSF coal train descending into Elliston to cut out a mid-train helper set. During this move, the manifest I saw earlier showed up and started the climb up Mullan Pass.
