Already responded to someone else giving more detail, but TLDR is: great experience, seats / bed were comfortable enough, and food was fantastic.
It was a fantastic experience. Trip total was about 5 days (Departed Vancouver around 3 PM Monday, arrived in Toronto at Noon on Friday).
I got myself a Cabin for One in Sleeper class, since I was traveling solo. The Cabin for One is definitely only for a single person. Once the bed was down, there was no room to move. But otherwise very cozy.
Food was delicious and included in the price of the ticket. Communal seating so I got to meet tons of people from all around.
They only open the Park Car (where the Bar is) to sleeper passengers in Off-Peak season. Otherwise, that section of the train is limited to Prestige passengers only. Luckily, December is Off-Peak, so I got to check out the bar and it is fully stocked and the bartenders I had were very friendly.
Snapped this photo back in December 2024 when I took The Canadian all the way to Toronto. Taking this train had been on my bucket list for a while, and it was well worth it.
Lemmy did not like me trying to upload the full resolution photo, so this is a screenshot of the photo instead lol
I absolutely have more photos. Only have a few of the inside of the train, though. I'm from the States myself, so I'm not too familiar about all of VIA Rail's lines, but this is not a special service.
