(c) STANDARD SECTION OF TREAD AND FLANGE OF WHEEL The investigation by this committee of the various types ofwheels in service on electric traction properties throughout thecountry shows that there is a very wide variation of wheel sec-tions in use, especially as regards flanges and treads. An in-spection of the data sheets demonstrated that it was almost im-possible to select one wheel which would meet all the varyingconditions. These sheets also showed conclusively that wheelsof a considerably narrower tread than the increased weight of 74Q STREET RAILWAY JOURNAL. [Vol. XXX. No. sented by Wheel A. To meet these conditions yourcommittee recommends Wheel B (Fig. 9), with atread of in. wide and a flange in. high, thisflange to have the same general dimensions as WheelA with the exception of the height above the tread line. In mounting and gaging wheels it is understoodthat the gage line is at a point on the flange the wheel tread, and your committee recom-mends that the wheels be gaged in. narrower i—than the gage of the track, the track gage being meas-ured between points in. below the tops of therails. RECOMMENDATIONS FOR FUTURE WORKThe investigation conducted by this committee dur-ing the past two years indicates the need on the partof the association in the future for a standing com-mittee or standing committees to take charge of thechanges and progress in electric traction extent of the field suggests the desirability ofdividing the subject among various committees, ashas been found necessary in the case of s
