The new com-pany, under the head of its president, Geo. C. Bishop, hasconsiderably broadened the former plans.

END AND SIDE VIEWS OF DETROIT PARLOR CAR cooled transformers, three with 33,000-volt secondaries andfour with 6600-volt secondaries, one of the latter transformersforming a reserve. At Academy Junction there will be four water-cooled trans-formers, 25 cycles, 800 kw, reducing the single-phase, 33,000-volt current of the transmission line to 6600-volt current suit-able for delivery to the cars. These transformers will supplythe current necessary for the Baltimore and the Annapolissections of the line. The sub-station at Academy Junction will be located ad-jacent to the car houses. For greater safety in inspectingand handling the cars, all of the trolley circuits in the carhouse will be arranged for 600-volt direct current, and forthis purpose two 300-kw motor generator sets will be in-stalled in the transformer sub-station, changing the 6600-voltalternating current to 600 volts direct current. The motorend of these motor generator sets will be connected directto
