Railway mechanical engineer . of 310 tons at a speed of 60 km.( miles) per hour on 10-nim. grades (.01 per cent) the c\linder walls toward the center, instead of outward, thecylinders thus being partially closed at the rear ends. Thecylinder heads are bolted to the inside face of these flanges,being applied from the inside of the cylinders. On the outerface of each cylinder head, which extends through the open-ing in the end of the cylinder, is cast the lug which sup-ports the guide bar. Jhc steam distribution is controlled by one piston valveon each side of the engine, driven by one set of Walschaertvalve gear. The ends of each piston valve are in. indiameter while the middle portion, which controls the dis-tribution to the high pressure cylinder, is in. indiameter. The use of this type of valve is not unusual inEuropean practice. The valve motion is reversed by a screwgear which does not differ essentially in its design fromAmerican practice. The main frames are of steel plate in. thick, with. -7S7J 039^ ^ \&&^- iJJt! -44^067 Sectional Elevation of tile Boiier over curves of 400 meters radius; and a load of 340 tonsat a speed of 100 km. ( miles) per hour on level trackover cur\es of 700 meters (2,297 ft.) radius. The engines are of the four-cylinder, balanced compoundtype. The low pressure cylinders are placed between theframes and drive on the cranked axle of the leading pair ofdriving wheels, while the high pressure cylinders are out-side the frames and are connected with the second pair ofdriving wheels. The high and low pressure cylinders on each side of the en-gine are cast integral with the half-saddle. The low pressurecylinders are raised and inclined to permit the removal ofthe pistons and the construction is somewhat different fromthat used in .American practice. It will be seen on the eleva ■tion drawing of the locomotive that the flanges to which therear low pressure cylinder heads are bolted, extends in from front rails of
