. Electric railway journal . JOURNAL. 595 elly turbo-generators. Each turbine has a maximum out-put of 2600 hp at 1500 and is provided with a surfacecondenser. An automatic auxiliary valve permits the tur-bine output to be raised to 3000 hp. The generators are ofthe Siemens-Sohuckert type, and are rated at 2000 kva at5000 volts, 25 cycles. Both classes of generating units havetheir speed controlled from the switchboard. By means of the Scott system of connections, the 5000-volt, 25-cycle, three-phase current from the generators isconverted to 10,000-volt, two-phase current by four 600-k

This special arrangement part of which contains the switch and the upper part the220-volt operating motor and relay for automaticallyopening the switch on overloads. The oil-switch motor,which is hidden in the view mentioned, is operated from themain switchboard, where green and red lamps indicate thein and out positions. An alarm sounds when a high-tension switch opens under
