LOCOMOTIVE ENGINEERING. 457 * # t. 458 LOCOMOTIVE ENGINEERING. Damage Done by Worn Tires. There was a very good report on Hol-low Tires read at the last RoadmastcrsConvention. The principal part of thereport reads: The damage to spring-rail frogs fromthis cause consists mainly in batteringand shearing of? the wing and point. Itis on this class of frogs that the greatestdanger of derailment from hollow tiresexists, for in trailing the frog the tendencyof the hollow tire is to crowd the springwing out; the gage is thereby widenedand the result is derailment. Again, each ;ind the general line of the frog to becomeruined, thereby necessitating frequent re-adjustment. .■\s a measure of safety, when hollowtires are allowed to run, the spring railshould be planed down where the tirefirst comes into contact with it; this willallow the wheel to mount the wing with-out so great a chance of the wing beingcrowded out and the engine deraile
