Twoso-horse-power motors will be installed for each elevator.At present, steam engines are in use at the barns, eachrunning several hundred feet of line shafting. Theexpensiveness of small steam plants is well known, andthe aggregate saving along this line will be considerable.The Hghting and power load will come at a time when electric railway man coming to Chicago, is a model ofneatness and good engineering. It is a station in whichno extravagant expenditures have been made, but it hasalways been the policy of the City Railway managementto omit nothing which will add to the economy and relia-bility of its plants.

On each end of this shaft is a clutch forthrowing in a 700-horse-power Westinghouse four-pole generator. The ul-timate capacity of the sta-tion is thus 7,000-horse-power, which is ample todrive the whole system,cables and all, if it is de-cided to do so. Theswitchboard bus bars arecalculated for 10,000 am-peres. The switchboardis the Westinghouse stand-ard, but ammeters will beput in the feeder circuitswhen more machinery isput in.
