For the lighting of the station there is another continu-ous current rotary converter which runs at a speed of900 rev. 4 amps, at 600 volts, and delivers current at novolts pressure. All the electrical machines were furnishedby the Elektricitats-Aktien-Gesellshaft, formerly W. Lah-meyer & Co., of Frankfort-on-Main. All machines in theengine and dynamo room can be reached by a 12,500 kg.(27,500 lb.) crane. Three arc lights illuminate the room. In the boiler room are two water-tube boilers of 220 sq.m.
