The history of the Atlantic Avenue Tunnel. The world's oldest subway built in 1844 by the Long Island Rail Road. Sealed in 1861, with a circa 1830's steam locomotive left buried behind a wall. Said to contain the lost diary pages of John Wiles Booth, assassin of U.S. President Abraham Lincoln, exposing an over 150 year old conspiracy. Plan for the reuse of the Tunnel as an historic attraction, possibly featuring streaming full immersion 3-D holographic video, more.
