31 Days of Notable Women-Mary Walton, railroad inventor

Old Railroad Car-b&wIn 1879, Mary Walton developed a method of deflecting smoke stack emissions through water tanks and later adapted the system for use on locomotives. In the 1880s, many cities developed a mass transit system using noisy elevated trains. To reduce the noise, Walton invented a sound-dampening system that cradled the track in a wooden box lined with cotton and then filled with sand. She received a patent for the system on February 8, 1881, and later sold the rights to the Metropolitan Railroad of New York City.
