This steam main to the turbine passesunder the engine-room floor and across the width of the build-ing to the turbine plant under the switchboard gallery. Thepiping in the half of the station not shown is similar to thatwhich has been described and another steam main for theturbine is installed in the other half of the station. Shouldone section of the plant be inoperative, steam will yet bed\ailable for the operation of one of the turbine units.

The mains for the turbine steamsupply are 7 inches in diameter. All valves in the high-pressure mains are . motor-operated with remote controlswitches in the switchboard gallery. It will be noted on the vertical section of the engineroom that a free exhaust main extends throughout the lengthof the building and at the elevation of the cylinder low-pressure cylinder on each engine connects with thisfree-exhaust main through a back-pressure valve on top of aT. The horizontal end of the T through which, under ordi-nary conditions, the exhaust steam is discharged, leads directto the inlet of a Prescott barometric condenser. The con-densers for the eight engine units are installed in a rowin the centre aisle between the two lines of engines. Underthis row of condensers and below the present floor are theintake and discharge cisterns. This arran
