The RR car depicted in the TV show on the History channel was placed under the Waldor Astoria during the late 1930s to early 1940s for the use of president Roosevelt. It looks like it has not been used, it's rusting, and it is sealed. Probably no one has been in it since WW2 and its wheels rest of friction bearing trucks. My guess is that the Feds have forgotten about it and someone should claim it and open it to see what that "baggage" automobile carring car has in it.
