a route distance of 133 miles. The initialsection from Mullens to Princeton has now been inop)eration about a year. The 11,000-volt alternating current system was se-lected for this electrification and the system layout wasbased on twelve and one half million tons of coal an-nually, hauled east from Europe. The initial locomo-tive order of 36 motive power units was intended tohandle 8 million tons annually. A power plant, owned and operated by the railway, for reconnection at 22,000 volts when the increased traf-fic demands of the railway require the higher trolleyvoltage. At points between the main transformer stations arel^Iaced balancer stations which contain auto-transform-ers. These are connected between the trolley and bal-ance wires with a point on the winding corresponding to11,000 volts from the trolley terminal connected to therail. The trolley-feeder circuit thus constitutes an aux-iliary transmission line. The Locomotives Each road locomotive, of which there are ten, con-

Profile and Map of Virginian Railway, Showing Electrified Zone and located at Narrows, Va. contains four 12,50G-kv-a.25-cycle, single-phase turbo generators. There are fivewater tube boilers with provision for a sixth, each ratedat 1521 b.h.p. Pulverized fuel is burned and this sys-tem of firing has been found well adapted to rapidlylluctuating loads. From the generators, power passes through four10,000 kv-a. oil-insulated, water-cooled transformerswhich raise the potential from 9,800 volts to 88,000volts. Two transmission lines run east and west fromthe 88,000-volt bus, to which the high tension windingsof the transformers are connected. Seven transformerstations are located along the right-of-way. The trans-formers in these stations arc known as three-coil trans-formers ; the high-voltage winding is connected to the88-kilo volt line in the ordinary way, but the low voltageis divided into two parts. One of the low-voltage wind-ings produces 11,000 volts and is connected betweenthe tr
