The shape of the gussetplate is such as to provide for the diagonal braces beingriveted thereto and concentrating the strength of thestructure. The center sills have spliced ends to facilitaterepairs. The sills proper do not extend to end sills, buthave built up extensions riveted thereto. In case of a. damaged end, it would not be necessary to remove thecenter sills, as might otherwise be required. The end sill is a flat plate bent to Z shape and rein-forced by a plate of the form shown in the plan drawingof the car and in the detail drawing of the sill. This up-per plate is riveted to the top flange of the Z and to thetop flanges of the side sills. The diagonal braces areriveted at one end to this plate and at the other end tothe bolster gusset as before mentioned. The posts forming the vertical members of the sideframing are 6 ins. channels weighing 10.5 lbs. per foot, and 7 ins. channels weighing 14.75 lbs. per foot, 6 ft.3 ins. long, and the angle braces are 3 by 2 by }i in.angle irons 7 ft. 6 ins. long. The arrangement of thestructural parts constituting the side framing is clearlyshown in the drawing, and by the half-tone engravings. The length from back to back of end sills, as previouslygiven, is 28 ft. 6 ins.; width over side sills 9 ft. 5 ins.;
