ELECTRIC MOTIVE POWER Tbe power bouse wbicb furnishes steam for heating alsosupplies electric current at 550 volts for operating the variousshops. The driving is by electric motors throughout. Tbe powerhouse has three Babcock & Wilcox water-tube boilers, rated at300 bp, equipped with Babcock & Wilcox automatic stokersand Link Belt conveyors. The electric generating plant con-. FIG.

These units are remarkably smooth in voltage of 500 was chosen as the pressure at which tbe shopsshould be operated, because of the possibility of using for tbeshops the regular railway current if tbe shop power bouseshould be shut down, or, on tbe other band, using the shoppower plant for moving cars at night in case it were possibleto shut down tbe larger power houses. Ordinarily the motorsand lights in tbe shops will not be run on a grounded circuit. Shafting in the shops is divided into sections with a motordriving each section independent of tbe cars. Thus in themachine shop there are three General Electric motors of 35hp, 30 hp and 25 bp respectively. Tbe motor repair departmentis driven by an old railway motor, and tbe departments on thesecond floor of this building ar^ driven by another similarmotor. The blacksmith
