The Bonar continuous oiling system has been installed in April 27, 1907. ELECTRIC RAILWAY REVIEW 551 connection with the turbine oiling system. The apparatus islocated in the condenser room and is composed of two filtersand one oil tank and a steam pump for raising the oil tothe storage reservoir on the gallery in the turbine room. Thestorage tank is also connected to the oil tanks of the it is desired to change the oil of the turbines the valveis opened to the filters and the oil (lows into them by Pittsburg & Butler Street Railway—Transmission Lines. When the oil is all out the valve is closed and the valve tothe storage tank is opened. The gauge board has mounted on it one pressure gauge,one pyrometer, two vacuum gauges and one recording steampressure gauge, draft gauge and mercury column for checkingthe vacuum gauge. The transformers are located in a room provided at thenorth end of the building. This room, which is 40 feet 6inches long by 16 feet wide and 12 feet 6 inches high, is suffi-ciently large for six 500-kilowatt oil cooled transformers, ofwhich four are now installed. A feature worthy of attentionis the mounting of all the transformers on wheels. Thisarrangement permits the ready removal of any transformerin case of accident and the substitution of a new one in itsplace. The roof of this room forms the gallery upon whichare mounted the stick type circuit-breakers, barriers, chokecoils and lightning arresters. The transformers as at present
