Exploring Track 61: The Hidden Subway Track Beneath The Waldorf-Astoria
First used by General Pershing in 1938, this short-lived line secretly carried Franklin D. Roosevelt to his private suite at the Waldorf-Astoria hotel, and whose platform later played host to Andy Warhol's "Underground Party" in 1965. Today, the original train car and elevator that FDR used are still standing on the mysterious line. See photos here, courtesy of Gothamist.
