[Vol. XXV. No. 8. THE SOLID FORGED AND ROLLED STEEL WHEEL FORSTREET RAILWAY SERVICE Probably no one feature of the question of electric railwayoperation is of more interest and importance to operating menthan that of the type of wheels to be used for the best the rapidly increasing stress of service in all features ofrailway work, in the form of heavier rolling stock, fasterschedules, etc., the demand has come for similar increases instrength in the wheels to properly carry the loads. It has longbeen evident that something stronger than the chilled cast-ironwheel should be used under electric cars, especially those oper-. THE NEW SOLID FORGED AND ROLLED STEEL WHEEL FORSTREET RAILWAY SERVICE ated under high-speed conditions and upon tracks that are nonetoo smooth or straight. The conditions under which electric carwheels are operated have too often been wrongly comparedwith those met by wheels under passenger cars in steam roadservice, which is manifestly incorrect; in the latter service,wheels are called upon to carry heavy weightsin the car body carried through the trucksprings, but in motor cars the wheels have tocarry not only the heavy car body weights butalso the uncushioned loads of the heavy motorsthemselves. For satisfactory operation, wheels should, tomeet the severe requirements of present condi-tions of electric railway operation, be abso-lutely unbreakable in any part and free fromdefects incident to manufacture; they shouldalso have wearing surfaces of great density andsolidity, and also be of the proper hardness toresist rapid wear.
