There arc parts of the engine that are of unusual in-terest and merit, that testify to the great advancementthat has been made in the use of cast steel in modernlocomotive design. Through the courtesy of Mr. McConnick, we are ableto present in addition to the photograph of the completedengine, photographs of the cast steel frame bed. includ-ing the deck or cradle casting, all in one piece. This one-piece device measures 52 feet 2y2 inches long, has a. Mountain Type Locomotive of the Southern Pacific Railway Having One-Piece Cast Steel Locomotive Bed one fabricated by machinists from a combination of greyiron castings, bolts, bars, frames, rods. etc. In the August 1923 issue of Railway and LocomotiveEngineering: there appeared a description of one-piececast steel underframes for box cars. These units displacedapproximately 800 individual pieces or parts used in build-ing up or fabricating a similar structure. Years ago had anyone predicted that large locomotiveframes, including deck plate, cradle and the numerousbrackets, would he poured in one casting he would havereceived scant consideration, yet that is exactly what isbeing done and is now an advanced practice.
