This is a great trip though VIA does some of the most scenic parts of the trip at night. Since they started offering Prestige Class regular sleeper passengers can not enter the rear Park Dome car for much of the trip. Paying the extra $ gives a lot of extra perks. I have done the trip a few times before the upgrade great trip thanks for your photos. The .... gate photo you show is the narrowest part of the Fraser River Canyon. A great place to watch the trains go by, has a gondola ride to get you low over the river. You were very lucky to have such good weather and get a shot of Mount Robson. Food is always excellent.
If you are keen on seeing the best of the scenery ride the Rocky Mountaineer they have 3 routes through B.C. all by daylight. The food and service especially in Goldleaf dome class is excellent like VIA. (VIA has the better dome cars for view, though only room for a few people.) The Rocky coach class is good enough for seeing the scenery. The CP route to Banff is great as is the BC Rail route through Prince George. You can also take a B.C. ferry Prince Rupert up the coast and take the VIA Skeena train to Jasper with dome car access 2 day daylight trip with great scenery as well.
