Yes, train travel is all about the voyage. Maybe some go on cruises for the same effect. Though I also went coach with my kids, they were old enough to do puzzles with, read to, learn to knit, etc. At home we were always busy and when at destination we were busy. On the train we were suspended in time, learning, playing games,being together and enjoying as well as learning about the geography as it passed. After the kids left home though, my time was better spent working and flying. If we get on top of Covid a bit better, I’ll be back on the train. I don’t want to pay those high roomette fees.
Abroad, in India, China and Thailand back in the day, train travel was an amazing adventure and a view of culture and scenery up close.
