The Waldorf-Astoria is perhaps New York's most prominent monument to jazz age luxury and glamor. It's been the traditional residence for US presidents and foreign heads of state when in town (the "presidential suite" was meant rather literally there).

Built over the below-grade railyard of Grand Central Terminal, the hotel was equipped with a private rail siding and platform where guests could park their personal railcars(!). (Andy Warhol once threw a party on the platform.)
