This is a few months after the fact, but to answer your (or anyone else who still has questions): the Empire Builder passed through the area but did not stop at the West Glacier (Belton) station. People had to board (or deboard) at either Whitefish or Essex (the two closest station stops to West Glacier), or one could go all the way to Glacier Park Station (East Glacier). I don't know, though, if passing through fire-proned areas affected the time-keeping of the train, but when I called "Julie," the train arrived in Portland fairly close to schedule.
