That pretty much describes long distance North American rail generally. At least in the US, I'd add that it's not only slow but could be delayed by a day or more. I've occasionally toyed with the idea of taking one of those trains for at least part of their route but I have a feeling that it's one of those things where the idea >> the reality and it would get pretty old once the novelty wore off.

Later this year I'm going with a more luxurious version instead (ocean liner).

Nowadays for sure. But before the trans-Canada highway and before commercial flight, it was a pretty great deal!
