The reversing switches have,as will be seen, three positions. The two extreme positions arefor backward and forward running, respectively, while the. VIEW OF POWER STATION, SHOWING GENERATORS AND SWITCHBOARD center position is for taking the cars into the car shed, wherea special low-tension overhead trolley line is provided. Forthis purpose, when the cars arrive at this point the switchesSzv are closed and the low-tension trolleys LT are put intooperation. The transformer reduces from 5000 volts to 260volts, and the barrel controller switches this voltage step bystep on to the motors. Aprii, I, 1905.] STREET RAILWAY JOURNAf, 593
