You do realize that Amtrak long distance routes offer such accommodations?
I mean yeah, the trains themselves are slow as shit and might not go where you want, but superliners and viewliners have some interesting accommodations.
Train pricing is utterly insane, I have tried the last few years to find an affordable alternative to flying/driving by searching for long-distance or overnight Amtrak options (for Southwest area), but have consistently failed to find tickets less than $500, regardless of time of year.
