One-Plece Cast Steel Underframe for Southern Pacific Box Ca tive or car construction many of recognized authorityindicated lack of faith in their suitability, and it is aregrettable fact that in their earlier use in locomotiveconstruction, many of the parts, particularly driving,wheel centers, were made entirely too light resultingin failure which was charged to the material, when itproi)erly should have been charged to faulty design, asthe material was far superior to cast iron. Among the manufacturers of locomotive and carspecialties, particularly of cast steel parts, the Com-monwealth Steel Company of St. Louis, Mo., was apioneer in the field, developed a great variety of de-signs, and has done much to reduce the trumber ofparts, by making single castings take the place ofseveral pieces. Some 20 years ago a railway motive power officerconceived the idea of making a locomotive enginetruck all in one steel casting, possibly the outertruck frame jaws thereby reducing the numbe
