#318

This eight-wheel 0-8-0 heavy steam switcher was home-built at the TRRA's Brooklyn, IL, shops and was the first steam locomotive built with a one-piece solid cast steel locomotive bed that included its cylinders with the frame and pilot beam. This intricate and difficult casting was made by the Commonwealth Steel Company of Granite City, IL, later General Steel Castings, and its success led to this type of locomotive bed being used on nearly every modern steam locomotive. It was one of the principal design developments of the 20th century steam locomotive, replacing as many as 400 parts bolted and riveted together in a cast steel tank bottom with welded sides and bracing. The locomotive has 52-inch drive wheels, 26 by 28-inch cylinders, weighed 209.5 tons in working order, and its boiler worked at 200 pounds pressure. Engine and tender are 53 feet 6½ inches long. It was purchased from the railroad and donated by the General Steel Castings Foundation in 1956.
