Yes, in the USA Amtrak tends to be quite a bit more expensive than the equivalent trip by air. And far slower. Maybe excluding some of the east coast commuter routes.
Very different experience though. Fast and deeply uncomfortable vs long and chill. I'd prefer the latter when feasible but it obviously isn't always.
