Journal Pittsburgh Car—Plan and Elevation Showing Door and Seat Arrangement April 11, 1914.] ELECTRIC RAILWAY JOURNAL 811 original controller has been in use for more than oneyear it is still operating satisfactorily. However, boththe main switch and the bridging cut-outs for themotors have been in a process of development until veryrecently and details as to their construction are notavailable. Owing to the practical elimination of resistance andto the method of making the transitions, the new con-troller has eliminated most of the losses inherent in theolder types. To demonstrate the extent of this savinga comparative test was made between two cars of ex-actly the same weight and with the same was equipped with the new controller and one witha controller of the standard type. The test lasted dur-ing a period of three months, and the cars changedruns every day; that is to say, a certain crew wouldhandle one car on one day and the other car on the nextday.
