directly into the trolley circuit at 2200 volts, with no out-side transformer sub-stations. Owing to the fact that 25-cycle three-phase generators arealmost universally used to supply rotary converters in existinginterurban railway systems, the General Electric Company hasadapted both the design of the compensated motor and the a. c.distributing system to operate from existing 25-cycle generatingstations. As the alternating-current motor is single-phase, a induction motors, etc., the preferred arrangement to balancethe load at each sub-station is to install three-phase, two-phasetransformers connected two-phase on the secondary side andfeeding separate trolley sections from the two phases. Suchan arrangement is also shown in the lower diagram on page284. The car equipped with the compensated motors weighs 30.4tons total without passengers, and is geared for a maximumspeed of about 43 miles per hour on level. The car manufac-tured by the J. G. Brill Company has a 32-ft. body, is 43 ft.
