Seve-al examples of recent installations of this kind are illus-trated in the accompanying cuts. Fig. I shows an equipmentemployed by the Brooklyn Rapid Transit Company for haulingcoal and ashes at its power plant. This is a 4-ton, 4-wheeledlocomotive of the mining type, equipped with two direct-currentmotors and a trolley pole standard. Fig. 2 shows another typein use by the Hawaiian Electric Company. It is employed to Georgetown, S. C. It is a 4-wheeled locomotive driven by twomotors capable of exerting a full load draw-bar pull of 4500 lbs.at a speed of 6 miles an hour. A .series-parallel controller isused on this locomotive, and permits of a speed of 3 miles anhour with the motors operating in series. Probably the mostinteresting example for the steam railroad men is that presentedin the illustration of the Carnegie Steel Companys equipment,Fig.
