This road, A, is now buying short piled, forged steel axles thoughno particular reason for the change is given. Of the axles now un-der cars 46 are cold drawn and 76 forged. The only specification isthat the carbon shall not be per cent; no tests are made. The wheels are bored to fit the axles, and not the wheelseatsturned to fit the wheels as is the usual practice; in replacing 1 ) of Cross Feed Center Line of I (c^ TT ^W iOi ^ I 1 aa^jfifal CLAMP FOR HOLDINO the wheelseats are not turned off unless the surface is bad. Eight-bolt gears are used, and are bored .01 in. smaller than the axle. The old equipment of the road in motors and trucks prevents theuse of a larger axle, that shown in Fig. 3, without expensivechanges. New cars recently ordered, however, have 4 in. indiameter between journals, with 3!/2-in. journals. Road B uses the axle shown in Fig. 6 under all its cars, which are20-ft. body closed cars seating 28 persons and 30-ft. open cars seat-ing 50 persons. The weight of the car body empty is given at 8,000lb., the truck at 3,700 lb., two motors at from 1,450 to 2,200 lb. used are Jones & Laughlins cold rolled steel and nospecifications other than those as to dimensions are given. All axlesare driven and the breakage during five years that steel axles havebeen in use is less than per cent
