rs. This battery can be chargedrither from the traction or lighting bus-bars as desired, the neces-sary voltage for charging being supplied by the booster, which canalso be driven from the traction or lighting bus-bars The batterybooster consists of a soo-volt shunt-wound motor, connected byflanged coupling to a shunt-wound generator and mounted, to-gether with the same, on a combination bedplate with three bear-ings. The generator has a rated capacity of 18 k. w., and is adaptedto give a range of ;>otcntial from 40 to 150 volts for running inseries with main generators for charging the storage battery. The boiler room contains three IJabcoek & Wilcox boilers, eachhaving 2,5.11 sr;. ft. of heating surface and capable of evaporating8,000 lt)S. of water per hour. The normal working pressure is 150tbs.

It is situated at the end of the engine room and contains threegenerator panels, fitted with automatic circuit breakers, with mag-netic blow-outs, also the necessary switches, so arranged that thegenerators can be connected direct to either the lighting or trac-tion bus-bars. The two battery panels are fitted with the necessaryregulating switches and magnetic blow-outs, and so arranged thatthe battery can be either charged from, or discharged to, either thelighting or traction circuits as desired. The two booster panels areso arranged that the booster can, if desired, in the day time be driv-en direct from the traction bus-bars, or used as an ordinary booster.the two motors being in series across the outside lines of the three-wire circuit and the junction being connected to the neutral wire.In this c
