These chan-nels are so spaced as to form the window and door posts, be-ing set back to back 2 ins. apart so as to form hollow sidewalls, within which the doors slide when opened. By refer-ence to the drawings, a very stiff girth and diagonal bracingwith gusset connections will be noticed below the windowsand in the end panels of the car. The corner posts are two4-ins. x -lb. channels, set transversely on the side sills. H=f2—S- 0—J •■ 1 tuz- ------- if,; \ 040-length-i
