On some travel videos I saw, it looked like the Stevens Pass route had some nice snow-covered craggy mountain type scenery, but given that 8 leaves Seattle at 4:55 PM, you're only going to see it in the high summer, otherwise it will be dark. On my trip last November, we left Seattle 3-4 hours late, and it was dark even before we left the station. Not dinner in the dining car the first night, either. They let the sleeper passenger order from a limited selection off the cafe menu. However, we did see more of western Montana in the morning. The scenery from West Glacier to East Glacier is pretty good, including some really good Rocky Mountain views going over the Continental Divide and a nice descent off the Rocky Mountain front. It sort of made up for the snowstorm over the Yellowhead Pass that obscured all the good views on the Canadian.
