Hear me out, I had a genius idea. Take one of the platforms at Grand Central in NY (they have more than the current railroad needs), load it up with a bunch of historic Pullman sleeper cars, and open it as a novelty hotel. Maybe roll out the red carpet to give that 20th Century limited feel. For an extra 30% add on, a bunch of actors will come along and play out a mystery crime on a train interactive theater cliche, with a script based loosely on that time John Wheeler lost a brief case of nuclear secrets on a sleeper train to DC.
The secret platform that FDR and other presidents have used is presently empty-ish (the railcar he used to carry his limo is abandoned there). But if you do this hotel, it will no longer be a secret..
Pfft that platform is hardly secret. I'm way further down the Grand Central Rabbit hole than that. Tell me when you've found out about the secret museum with the red carpet.
