The Grand Central Terminal is the nation's busiest train station, used by over 750,000 people daily. Between secret presidential tracks and a $20 million artifact hidden in plain sight in the main concourse, the history and inner working of Grand Central are fascinating.
The behind the scenes tour is guided by Dan Brucker, Grand Central's residential historian, whose extensive knowledge of Grand Central's history has been featured on programs ranging from National Public Radio to NBC.
