The old equipment of the station, which is retained forrailway service, includes a 300-kilowatt generator, direct con-nected to a 16 and 32 by 42 inch engine and two 250-kilowattbelted sets. It is planned to use the latter only at times ofpeak load or in other emergencies when economy of operationis not the first requisite. The balance of the machinery isused for power or lighting service. The 300-kilowatt set ispiped to the barometric condenser so that either that or a minimum interference with piping and other station fixtures,and the space occupied was so small that very little delaywas occasioned by the existence of the Jacksonville Power Station—Roller Supported Pile DriverInside Station. surface condenser originally supplied can be utilized. Ordi-narily the new condensing set will be used. All the otherold engines are provided with individual surface condensers,but the piping is so arranged that they can also exhaust intothe barometric condenser. In connection with the generator installation the railwayswitchboard was remodeled and six new single-circuit 1,200-ampere feeder panels added. The board now contains 16panels, of which three are devoted to alternating-current serv-ice and the balance to direct-current uses. The accompanying halftone engraving illustrates a port-able pile driver carrier which was used in the plants con-struction in connection with the foundation work for the newgenerating unit. The driver was installed on a frame carriedon two longitudinal timbers and free to move back and forthon roller wheels as shown. The cross timbers were strength-ened by
