It isconsidered on this road that the speeds above mentionedare nearly the limit at which it is practicable to work the and owing to the newness of the art of interurban railroad-ing, such practice is worth special notice. Perhaps thenearest approach to it found in previous practice is that onthe elevated lines of Chicago, and in this connection it maybe noted that J. S. Hamlin, the general master mechanicof the company, acquired a part of his experience in theshops of the Metropolitan West Side Elevated, of Chicago. As the present shops are somewhat cramped, a new shopand car house is to be erected next spring. These shops. FIG. 7.—STANDARD MOTOR TRUCK, M. C. B.

Since the track ballasting and surfacinghas been completed so that the track is smooth, there is ex-tremely little trouble from the trolley coming off at highspeeds. While at the speeds so far attained there is nopractical difficulty with the trolleys, for higher speeds andgreater length of trains the trolley would be out of thequestion. The trolley wheels used are 6 ins. in diameter,and, of course, wear out very rapidly in this service, notonly on account of the wear in the bearing of the wheel,but because of the volume of the current that is conductedfrom the wheel to the wire. At full speed the current re-quired on a level is about 150 amps. The maximum cur-rent taken during acceleration when the motors arethrown into multiple is from 300 to 350amps. Considering the volume of the cur-rent which must be taken by the trolley-wh
