We heard from a reliable source that during a recent late night excursion to the Atlantic Avenue Tunnel area, a 19th century LIRR steam locomotive was discovered. Allegedly a television network was on hand during the discovery, said to be working from street level with engineering consultants and a Cesium Vapor Magnetometer; the result was "an immediate, strong, clear unmistakable reading." The roughly 175 year old machine is said to be in its original state, and the "only one of its kind in the world."
The tunnel is closed, with the Department of Transportation and FDNY threatening arrest for any who enter—even Bob Diamond, who rediscovered the historic underground spot back in the 1980s. Will they budge, at least to uncover this historical artifact? In the past they've tried to block further tunnel access with red tape, so it's unlikely, but we've contacted them for comment and will update when/if we hear back.
