. The Street railway journal . ermechanic. The ordinary chilled iron wheel with i-in. flange is ruinous tospecial work in the city. We formely used a 500-lb. chilled ironwheel with 2^4-in. tread and J^-in. flange on our Lockport divi-sion, and a 450-lb. wheel with the same tread and flange on theNiagara Falls division. With both of these wheels we had anunlimited amount of trouble with chipped flanges, having toremove many of them for this reason before they were half wornout, and in several instances, after making but a few trips. As amatter of precaution, I found it necessary to have all wheels care-fully examined each trip at both ends of the lines. We are now using two types of wheels under our interurbancars; steel tired and rolled steel wheels, with 2,y2-. tread and%-in flange. The rolled steel wheels have given very fair results,with the exception of a few which have had to be removed onaccount of defective plates. As to flange wear, the results withboth have been very good. The rolled steel wheels made an. A COMPARISON OF FLANGES SHOWING WEAR average of 35,000 miles before they were taken out to be turnedup for the first time, and a few have been turned up the secondtime with an average of 25,000 miles for the second run. We haveonly one car equipped with steel-tired wheels that has been inservice long enough to get any definite data as to wear of flangeand tread. These wheels have been in service about five and ahalf months and have made 34,960 miles. The flange wear is verysatisfactory, as can be seen by the following sketches showingsection of tread and flange when new and after making the abovemileage. You will notice that the flange is lower after having been inservice than it was originally, although I use a brake-shoe thatdoes not wear on the flange. This I attribute to the special workinside the city limits, the depth of the groove not being enoughto maintain a %-in. flange. However, we now have no morebroken or chipped flanges and, as a factor of sa
