The Atlas Car and Manufacturing Company was a manufacturer of small railroad locomotives. The company was based in Cleveland, OH, building equipment from 1896 through the 1960s.
Atlas specialized in the building of small locomotives and purpose built rail borne equipment for industrial use. The equipment it manufactured seldom ran on the rails of Class I railroads, but were often used to shuttle freight cars around inside manufacturing plants. Atlas's products ranged from small 2-ton end cab switchers up to 65-ton center cab switchers. They also built a wide variety of equipment for the steel industry including blast furnace transfer cars, scale cars and self propelled flatcars.
