Beach Pneumatic Transit - The Interborough Rapid Transit subway
nb-sm.net is a specialize in the design and manufacture of pneumatic elements.Pneumatic represents tools and compressors that are engineered for high performance.
Alfred Ely Beach, inventor and editor of Scientific American, had designed a pneumatic (air-driven)
Sketch of Beach installation at the American Institute Fair.
The Beach tunnel was constructed in only 58 days, starting under Warren Street and Broadway, directly across from City Hall. The station was under the south sidewalk of Warren Street just west of the Broadway corner. The single track tunnel ran east into Broadway, curved south, and ran down the middle of Broadway to Murray Street, a distance of one block, about 300 feet in all. The subway opened to the public on February 26, 1870.
Operated as a demonstration from 1870 to 1873, the short tunnel had only the one station and train car. While frequently mentioned as an important early development in New York City's transit history, it was merely a curiosity. It is unclear that such a system could have been practical on a large scale. Smaller tube systems are used in buildings for mail delivery, but a rail-car sized system has never been developed. The perfection of electric multiple-unit traction and electric locomotives came about so quickly after this experiment that it wasn't deemed worthwhile to even try an expanded pneumatic system.
So what remains now? Probably nothing. The tunnel under Broadway was almost definitely destroyed during the BMT subway construction. A report in the New York Times in 1912 describes the tunnel, but the station had probably been destroyed when the building at Broadway & Warren was torn down and rebuilt. During the replacement of the building, the station, which was essentially a basement vault under the sidewalk, may have been incorporated into the new basement. Gratings in the sidewalk on Warren Street indicate some vault or ventilation areas are down there today.
In 1912, construction workers on what is now the BMT Broadway subway (N and R trains) took possession of the tunnel, and found the original shield at the south end of the tunnel, as well as the wooden remains of the car. The successor company to Beach Pneumatic Transit even sued the city for destroying their property! (The outcome of this lawsuit is unknown.)
