The sys-tem finally installed is known as the single-phase, 11,000-volt trolley system, which consists of an 11,000-volt catenary-suspended trolley, from which current is collected by abow pantagraph on the locomotive. A transformer carriedin the locomotive cab transforms the voltage from 11,000 to750 and a phase converter, operating at the latter voltage,furnishes three-phase current to the wound-rotor inductionmotors, of which there are eight on each locomotive. Thesystem operates at 25 cycles. The motors are wound fortwo synchronous speeds, 14 and 28 miles per hour, and arestarted by inserting water rheostats in series with th
