If the break is in thelower rail the engine can proceed to the terminal with theentire train. BROKEN DRIVING TIRES. Forward Tire, Ten-Wheel Engine. If one of theforward tires of a ten-wheel engine breaks, the wheelshould be run up on a wedge to raise it higher thanthe thickness of the tire, making allowance for set-tling, the cellar removed if possible, a block fittedin place of the cellar and a block placed betweenthe bottom of the driving box and the top of thebinder. If the cellar cannot be removed, a nut shouldbe placed on top of the binder under each jaw ofthe driving box, blocking placed between the bindercellar, and the front end of the front equalizer chainedto the lower rail of the frame (Plate 86). The reasonfor blocking in this manner when the cellar cannot be. PLATE 86. 2IO BREAKDOWNS. removed is, that if a block were placed on top of the bind-er the full width of the driving box, there being moreweight on the driving box than on the cellar, and thecellar having more surface on the blocking than the driv-ing box width, the driving box would gradually work itsway into the wooden blocking, placing all the weight onthe cellar and cellar bolts, which could not bear it. Onheavy power where the pedestal is strong enough to carrythe weight of the driver, it will not be necessary to chainthe equalizer, but otherwise the equalizer must be chainedas in Plate 86, or with overhung spring rigging, a blockplaced in the spring saddle. If the side rods are notdamaged they should be left up. In all cases of broken tires the driver brake shouldbe cut out. A full train can be handled when the breakis on a front tire. Middle Ti
