The locomotive is to be given a preliminary trial on thePhiladelphia-Paoli 11,000-volt electritication of the Penn-sylvania. The locomotive is designed to operate on 11,000 volts,single-phase, 25-cycle current taken from an overhead con-tact wire. The current is supplied to the primary of a statictransformer which returns it to the track circuit and in so of operating at any intermediate speed from zero to the max-imum, by means of the rheostatic connections. The lowestof these speeds is m. p. h. and is obtained bv connect-ing the motors on either truck in cascade with each otherand in parallel with those on the other truck. It is contem-plated to use this speed only in slow movements and aroundyards. The other speed of m. p. h. is obtained by con-n
