This locomotive incorpo-rates many novel features inelectric-locomotive design, andis the result of several yearscooperative development be-tween the Pennsylvania Rail-road Company and theWestinghouse Electric andManufacturing Company. Itis distinctively a high-poweredmachine, built for high speedoperation. In wheel arrangement,weight distribution, trucks andgeneral character of the run-ning gear, it is the practicalequivalent of two Americantype locomotives coupled per-manently back to back. The connecting rods areall rotating links between rota-ting elements, and are thusperfectly counterbalanced forall speeds.
