The two ends of the locomotive areequipped with standard M. C.

The bolster is boltedrigidly to the side frames and theweight of side frames and bolster istransmitted to the equalizers through aheavy semi-elliptic spring on each side. The bolster casting extending alongthe side frames plays an important partin squaring the truck. The bolsters andframes are further stiffened by two

ELECTRIC LOCOMOTIVE FOR THE P.Referring to the mechanical con-struction of the locomotive, the cab isof the type which has been standard-ized by the manufacturers for switch-ing service, having, as may be seenfrom our half-tone, a main centraloperating cab, and sloping ends, con-taining the auxiliary apparatus. Theends are each a separate frameworkof angles and sheet iron bolted to theplatform and main cab so that theymay be removed without disturbingany of the apparatus contained there-in. The main cab is furnished with RY. L. & P. CO. arched cross ties located equally dis-tant from the center of the truck. Thebolster is rigidly bolted to these crossties at the center, and they in turn arerigidly bolted at the ends to the bot-tom tie bars of the frame. The centerplates, lugs for brake hangers and lev-ers are integral with the bolster cast-ing, thereby giving a design of truckwith a minimum number of parts andgreat rigidity. The driving axles are 6 in.in diameter and are made of h
