@New Haven Joe - And The Canadian doesn't come close to the Rocky Mountaineer (from someone who's ridden both), but then again that's not really a fair comparison because both Amtrak and The Canadian are government subsidized whereas the RM is strictly a private enterprise. 🤑
If you have not ridden Prestige Class on the Canadian, which was introduced in 2014 after rebuilding some of the Chateau sleepers in 5 compartment bedrooms with private baths and showers and the complete rebuild of the Park Observation to provide a more open lounge by reducing the bedrooms to 2, you have not experienced the full level of accommodations the Canadian has to offer currently. It is simply a level beyond anything Amtrak has ever offered.
Having ridden both as well, I can say simply that the experiences are different. The Rocky Mountaineer is outstanding and the service top notch. However, I will say that I honestly enjoyed the Canadian more personally. If we had what is now called Sleeper II service which is a private compartment in a Manor Sleeper, I would not have had quite the same experience. Those cars and accoomdations are showing their age. Prestige is first class all the way down to the nice book on the history of the train, the leather baggage tags, the all-inclusive food and drinks, and exclusive access to the Park car until 4 pm every day. The room in Prestige is quiet and quite large by railroad standards and featured a murphy bed with a comfortable mattress over the L shaped sofa for daytime room use. They even have keyless card entry to the rooms for privacy and security.
Again, the Rocky Mountaineer is a great trip, however I have a hard time comparing it to the Canadian for the class of service we purchased and spending 4 days / 3 nights on the train from Jasper to Toronto. I learned a great deal about Canada from both trips and would encourage anyone to do both.
