Electric railway journal . rgy at reducedpressure is delivered to the bus room on the first floor onthe west side of the building, passing upward and down-ward to and from oil circuit breakers located on the operat-ing floor above, until it is finally delivered to the under-ground cables connecting the transformer substation withStation No. 6. The connections in the bus room are soarranged that energy can be delivered from any set oftransformers to any outgoing feeder without interferingwith the general scheme of operation. Aside from theswitchboard and clean oil storage tank there is nothingon the operating floor except the 11,000-volt oil operating the switches when the ordinary circuit pro-vided for that purpose is not alive a battery of 66 cells,charged for a mercury rectifier set, is installed. The build-ing is heated electrically and for the circuits in the station,two three-phase transformers are installed; each of these israted at 40 kw. In the entrance room a 1000-kw, three-phase, 25-cycle. Rochester Power Plants—Busbars Under 11,000-VoltSwitches in Substation No. 33 transformer is installed. This steps up the voltage from11,000 to 18,000 for transmission over a wooden pole line27 miles long to Canandaigua, where a motor-generator setis installed for carrying the railway load of the Rochester& Eastern Rapid Railway. Aluminum wire is used on thistransmission circuit. The motorman who was responsible for the wreck onthe Berlin Elevated Railway last September, described inthe issue of this paper for Oct. 10, 1908, has been sen-tenced to 21 months imprisonment. mm £1~ u y I I 11 L —■— ■- j Q © \ » s «(Ss • ** mt i« = «•£ * ■Pi «* j * *«*&; •——*~ # • —ft, • f 0 w Ill February 20, 1909.] ELECTRIC RAILWAY JOURNAL. 33i RECORDING PATTERN MOVEMENTS IN BROOKLYN The mechanical department of the Brooklyn RapidTransit Company has developed several cards and otherforms to keep accurate track of the movements of pat-terns
