ABSTRACT:
A railroad car truck bolster has a centrally disposed vertically arranged longitudinally extending web. The web has spaced reinforcing means with the spacing of the reinforcing means being sufficient to cause certain fractures in the web propagating along lines of maximum shear stress at approximately 45 degrees to lines of principal stress to reach a reinforcing means at a point closer to the neutral axis of the web than the next adjacent external surface of the web. The bolster side walls have openings with the above-described spaced web reinforcing means being generally in alignment with the bolster side wall openings.
