Not the same, but I'm up the road from the Strasburg Railroad and they have some fancy cars you can dine in. I would love something like that from Lancaster to Philly or Philly to NYC https://www.strasburgrailroad.com/

Fun local news fact: someone left their excavator on the tracks and one of the locomotives crashed into it Wednesday !
