It is designed for operation at 25 cycles, a frequency whichhas been adopted as standard for single-phase railway service. Outside of cities there is used a peculiar form of bow trolleydesigned for high potential alternating current circuits. The trolleyIS mounted upon a thoroughly insulated platform, and is raised, low-ered and controlled by the motorman by means of compressed is therefore no danger at any time of contact with live partsof the trolley. The bow carries a large, flat aluminnm shoe, whichmakes contact with the under side of the trolley wire. For low potential service, whether alternating or direct current,a modification of the Union standard trolley is provided, as thebow type could not be used in the city of Indianapo
