Abstract
There is disclosed a light weight truck bolster for railway car trucks. Metal has been removed in the compression and tension members of the bolster near the center bowl. One longitudinal rib is located in each end of the bolster arms and a pair of transversely extending vertical ribs are located on opposing sides of the center bowl and extend from the tension member to the compression member. The disclosed light weight truck bolster satisfies the Association of American Railroads ('A.A.R.') design qualifications for truck bolsters while weighing significantly less than traditional truck bolsters.
