Subsequently three more 1000-kw units werecontracted for. steam turbines being ordered. It was found that. FIG. 12.—ENGINE ROOM, LAND COST PER HORSE-POWER the turbine saved 900 sq. ft. of engine-room floor space and about38,000 cu ft. Had the whole plant been originally designed forturbines the saving of space would have been double theseamounts, and the cost of land, building and foundations been re-duced at out $50,000. An electric railroad plant in Ohio was some time ago installed,in which there are 500-kw generators direct-connected to cross-compound Corliss engines. Space was provided for two moreunits of the same size. For the increased power two 1000-kwturbine outfits were purchased, which will go in the space left, andleave room for another turbine of 2000 kw. Thus, the engine-room space planned for 2000 kw is found sufficient for 5000 kw. Itis estimated that the boiler-plant extension will be reduced aboutone-third because of improved efficiency. It is figured, too, thaia saving of $2,900 was effected on each 1000-kw foundation. October 18, 1902.] STREET RAILWAY JOURNAL. f 649 O
