the bigger question is…. Why not just ride from Vancouver to Winnipeg and back?
To be fair…. I rode in the winter when most of the rivers / lakes were frozen over so it was just lots and lots of snow for those first 2 days. It was novel for about an hour. perhaps I’ll try it again sometime in a warmer season.The scenery in Ontario is actually pretty interesting with all the lakes you see.
For me, the big attraction is the train itself. And I love sitting in the dome at night watching the play of light down the stainless consist as the signals change.
For scenery, overall the CZ is better. But the train is itself is matchless.
Went from Anchorage to Fairbanks and back in the 80s and loved the ex-UP ACF dome coaches. Went from Anchorage to Seward on a cruise connection train in the 2000s. Anchorage to Seward is the single most spectacular stretch of railroad I have ever ridden.It’s not an overnight train so not a direct comparison but you should give Alaska Railroad a shot - best of both worlds as far as scenery and great consist - although it ranks the lowest of the 3 as far as food. (VIA, Amtrak and Alaska RR).
