In Brussels, where the rail groove is 30 mm deep x 32nun wide, some experiments were made with cast-ironwheels, but they did not prove very satisfactory, and thesteel wheels are now used exclusively. The average lifeof the present tires is given by Mr. Dugniolle, engineer ofthe company, as about 65,000 km. At a cost for the tireof about 35 francs, plus 6 francs for two turnings, this isequal to an average of 63 centimes per 1000 km, not count-I. Street Railway Journal FIG. I.—STANDARD WHEEL OF THE BRUSSELS TRAMWAY ing the cost of removing the wheel from the car. Thecast-iron wheels used in Brussels rarely ran up to 60,000km. The trouble experienced from chipping with chillediron wheels in Europe cannot be attributed entirely to thenarrow groove used, however, because although mostAmerican roads use a wider groove than that employedin Europe, rails have been laid on a number of systems inAmerica where the groove is certainly no wider or deeperthan almost any in Europe, yet chilled iron wheels havegiven no trouble. For instance, the rail used by the Capi-tal Traction Company, of Washington, D. C, has a grooveonly 1 in. (25 mm) wide and 1 in. (25 mm) deep. This is,perhaps, the narrowest groove of any used in the UnitedStates, although the Havana Electric Railway Companyuses a rail with a groove 1 in. (25 mm) wide and i-§ in.(29 mm) deep, and the Boston Elevated Railway, on partsof its surface li
