New York's 1870 Subway Had No Engine, Just a Fan

In 1870, a New Yorker could pay a quarter, walk down stairs under a clothing store, and find a round, cushioned railway car waiting in a brick tunnel. No horse pulled it. No locomotive pushed it. A fifty-ton fan blew it with air. This is the story of Alfred Ely Beach's pneumatic subway under Broadway, and why two popular parts of the legend, "it was built in total secret" and "Boss Tweed killed it", do not hold up well against the newspapers of the time. Key facts US patent 59,739, granted 13 November 1866 to A. Ely Beach: a car in an air-driven tube for letters and parcels (mail, not passengers). Public reception 26 February 1870, public admission from 1 March 1870, 25 cents, for an orphans' home. Tunnel about 300 feet under Broadway, Warren Street to Murray Street, built with a hydraulic tunnelling shield. Roots blower, "the Western Tornado": about fifty tons (Beach's own figure). Beach's bills for a real railway: Tweed introduced the 1870 bill; the 1871 and 1872 bills were vetoed by Governor Hoffman; the 1873 bill was signed, but no money came in. 8 February 1912: officials entered the tunnel through the City Hall Park vent and found the tube in excellent condition.
