The tracks were raised several feet above mechanism, which is electric, is placed in a mechanical caseat the top of the pole or mast, where it is easy of inspectionand provided with protection in all kinds of weather. Thecompany is prepared to supply bottom post mechanism, how-ever, of the same design, when desired. The connections of athree-position automatic block signal for double-track lines isillustrated herewith. As yet the company has developed thesystem for use with the usual track blocks for steam lines THE GENERAL ELECTRIC COMPANY EXHIBIT BOOTH the floor to permit thorough inspection of the underhangingparts, and a side platform reached by a stairway afforded aclose view of the motor mounts. The entire equipment is simi-lar to that of the Westinghouse single-phase cars built for theVallejo, Benicia & Napa Valley road in California, the Blairs-ville and Derry line near Pittsburg, and other alternating-cur-rent suburban systems not requiring combination rheostaticcontrol for direct-current service over tracks within city limitspreviously equipped. The straight alternating-current systemwas exhibited as more desirable than the combination equip-ment. Alternating current for the operation of the motors wasobtained from a 400-kw rotary converter, running inverted,which received direct current at 500volts from outside the exhibitiongrounds. The latest form of West-inghouse multiple control for direct-current practice was also demon-strated in a complete car
