This only applies to sleeper car routes. You're on the traib for 2-3 days, mostly with no cell service. If you eat in the restaurant car, they will seat you with strangers. If you sit in the observation car, there's a bunch of other people sitting there too.
I did NY to Miami 18 months ago having spent a week in Washington/NY and was due for 3 days in Miami before flying home.
Saturday morning in NY looking at a few sights I hadn't seen (Trinity Church), then a relaxing train down to Miami. Beat flying and spending Sunday in a hotel room.
I didn't sit with anyone else in the restaurant car, but that does sound an interesting way to meet people from a whole different world. The Friday night in NY though I did sit at a bar next to other people, so I guess that was horrifying?
Had i been that against it though there was an option to eat in my room.
And creeping along for hours at 25mph because you're following a freight train is frustrating in its own way, even if you have a comfortable seat and food and drink.
