The company has at the present time seven locomotives con-tracted for, four of which have been already delivered. These areeach 20-ton locomotives, the frames of which were built by theBaldwin Locomotive Works and the equipment was furnished bythe Westinghousc Electric & Manufacturing Co. The cabs of sixof the locomotives are built so as to clear the trolley wires at aheight of 9 ft., and one locomotive, which is to be used entirely forswitching purposes in the city of Cincinnati, is built to pass undertrolley wires 7 ft. high. The frames, which are 14 ft. in length, aremounted on Baldwin trucks having 30-in. wheels and a 7-ft. wheelbase. The weight complete is about 24 tons each and the motorsare connected to the axles through double reduction gearing. Thedraw-bar pull with three-phase current at .1.000 alternations and

The company has no generating station of its own, but takes cur-rent from the Cincinnati Gas & Electric Co., which has a plant onthe bank of the canal near the Cincinnati terminus. This companyfurnishes three-phase current of 60 cycles at 4,000 volts pressure tothe Spring Grove converter station shown in the accompanyingillustration. This current is stepped down to 400 volts at the SpringGrove station and is two-phased by the Scott method of connec-tion of transformers. This two-phase current is led to a 450-h. ptwo-phase synchronous motor, which is direct connected to a three-phase. 25-cycle. 300-kw. generator, giving a pressure of 390 volts.Thence the current is led to 2S0-kw. transformers and stepped upto 33,000 volts for the transmission line. At points about 12 miles apart there are static transformer sub-stations, each of which is to be equipped with three 150-kw. trans-formers permanently connnected in del
