The facts as given by Mr. Hook tend to prove the theorythat in most cases where the flanges of motor wheelsbreak, especially after some service, the break does not in-dicate any defect in the metal, but is incident to the ser-vice. The difference in thickness between the flanges onone side and the other of the car must, of course, havebeen due to the grinding of the flanges against the railsin curving, and the location of the road must have beensuch as to bring this wear more to one side of the car thanthe other. This constant grinding on curves may be sosevere as to heat the tread and flange of the wheel to an. DOUBLE DECK CARS IN SYRACUSE more expeditiously in a new way. The result has been theconstruction of the four double-deck cars above mentioned,which are of the fifteen-bench, open type, very heavily con-structed below, and with the upper compartment capableof holding, on a pinch, 100 persons. We have shown ourability on more than one occasion to carry off a good-sized crowd at one load on one of these cars. Altogether,I can say that this class of rolling stock has proven emi-nently satisfactory. _ ♦♦♦ Interesting Wheels Records in Los Angeles There is considerable discussion as to the maximummileage ever made by an electric car wheel, but if LosAngeles does not hold the record, it certainly comes verynear doing so. T. J. Hook, superintendent of the LosAngeles Traction Company, reports that car No. 122,which is 38A- ft. long, and is mounted on Brill maximumtraction trucks, recently completed 185,000 miles with thesame full set of 33-in. driving whee
