The ratio of superheating to wa-ter heating surface is not as high, in thisengine, as in many other recent designs,but this is chiefly due to the compara-tively short boiler barrel, as the tubeshave a length of only 11 ft. 6 ins. This locomotive is equipped with valves, and the Walschaerts mo-tion. The crank pins are of chrome-vana-dium steel, and the materials used in theconstruction of the engine are in accord-ance with specifications issued by theAmerican Society for Testing Materials. The tender has a 12-in. steel channelframe, and the sloping back tank gals, of water and 8 tons of principal dimensions are as follows:Boiler—Thickness of sheets. ^ in.; G. M.

Locomotive No. 478, for the Chicago(ireat Western, represents a class whichhas been extensively built for that line,and is designated by the railroad companyas Class B-5. This engine weighs 155,-000 lbs., and exerts a tractive force of35,350 lbs. It has 21x26 in. cylinders and51-in. driving-wheels, and the workingpressure is 185 lbs. The locomotive is,therefore, of c
