In order to get congestion and filth off the streets of New York, Alfred Ely Beach had an idea for a pneumatic subway, pulled by a rope of air. A giant fan would drive a train through a tunnel, as fast as 10 miles per hour. After gaining the legislature’s approval for an experimental pneumatic tube for packages, Beach began working on a real subway.
