       In the late 1800s, cities were choking on pollution from steam locomotives. Trains spewed thick black smoke, filling the air with soot and making city life miserable. In 1879, American inventor Mary Walton, a New York resident and mechanic's wife, took it upon herself to tackle this growing problem.Walton’s design forced locomotive smoke through a water tank, trapping harmful particles and preventing them from polluting the air. Railroads adopted her invention, and her patent brought her both recognition and financial success. But she did not stop there. Elevated trains in New York City had become a constant source of unbearable noise.Walton studied the problem and developed a sound-dampening system that reduced the vibrations and noise produced by the elevated tracks.Mary Walton remains a rare example of a 19th-century woman inventor who made significant contributions
