Carrier bars pass through theseand rest on the trunnions of the spring caps, therebyforming the support for the bolster and locking the sideframes securely into position. As the carrier bars passthrough the bolster at a point on a level with the jour-nal bearings they deliver all side thrust to the frames,without any tendency to tilt the side frames, andthereby eliminate the necessity for a spring plank. Included in the Pennsylvania Railroad exhibit onTennessee Avenue near the railroad station is the 250-ton Pennsylvania electric freight locomotive. Thisrepresents the present maximum capacity for a single-cab unit. The principal object in the design was to con-centrate the greatest power possible within the limita-.

This locomotive has4800 hp. capacity, with 140,000 lb. starting tractiveeffort.
