In this country it’s not often Amtrak’s fault. They have to give freight trains the right of way. If they didn’t, schedules would be so much easier to keep.
But definitely, train travel isn’t for everyone. It has to fit one’s personality and schedule to be enjoyable.
Back in my younger days I thought I’d love the super fast trains (that the US doesn’t have yet). I don’t. Sure they get you places quickly, but you can’t really see anything. On planes you have distance to still see the scenery. On fast trains, not so. We’re scenery lovers. Even Amtrak’s routes that go predominantly through trees aren’t our favorite.
