This girder is set at such aheight from the rail as to permit the draft gear to be placedbetween the centre sills at a point near the centre line, so that allpulling and buffing strains are transmitted in a direct linethrough these sills. The body of the car is supported from the centre sills by twocross bearers and the end sills. The cross bearers are locatedabout 19 ft. from the end sills and are about 32 ft. apart. Theyare constructed of pressed steel shapes and provided with coverplates, so as to make a very strong and rigid support. The end. SIDE AND ROOF FRAMING—PENNSYLVANIA STEEL PUSTAL CAR.
