The center sills are of 15-in., 33-ll>. channels, reinforced al the center of the car for aLength of IS ft. by 3 x 4 x y^-in. angles. These angles areriveted to the inside faces of the channels at the top and bot-tom, converting the channels into I beams at the central por-tion of the car. In addition to these angles the center sillshave \i x 8 x 4 ft. 0 in. cover plates between the drop doorsand 10 x 8-in. tie plates at the center of the car. The side:sills are also 15-in., 33-lb. channels, reinforced with top andbottom :: x 4 x ]--in. angles, through a distance of IS ft. atthe center of the car. The upper angles are inside of thechannels and the lower angles outside, as shown in the sec-tional view. At the center of the car are diaphragms of platesand angles reaching from the center to the side sills. Theseare plate girders with two angles at the top and two at thebottom. At each door o
