Thus by opening the three doors on one side of the weight. Hence the car body and its load is supported en-tirely by a truss frame occupying the whole side of the car be-tween the plate and sill. This truss is arranged in five panels,the center door occupying the middle panel. The bottom chordof the truss is a 6 in. channel forming the side sill and extend-ing continuously from end to end of the car and the top chord 404 AMERICAN ENGINEER AND RAILROAD the car. The side sills are the 6 in. channels already bolsters are of the built up type and carry the spring draftgear in the center between the sills. The needle beams, of whichthere are four between the bolsters, are composed of angles setbetween and secured to the longitudinal sills. King posts aresecured to the center sills at the needle beams and truss rodswith turnbuckles transfer the load from the center sills to the END VIEW OF ALL-STEEL CAR—HUDSON COMPANIES. is a similar channel forming the side plate. The vertical parts ofthe truss are 8 in. channel posts, spaced uniformly and placedbetween the pairs of windows. Below the window sills these postsare braced by diagonal members to the bottom chord and abovethe windows they are reinforced by angle irons and steel plates,which arch over the pairs of windows and are riveted to the topchord. At the center door the top and bottom chords are rein-forced by bulb angles, as is also the bottom chord below theend doors.
