Abstract

A railroad car sideframe of a truck is provided with a pair of identical twin ribs which are designed to reinforce and strengthen each of the pedestal frames against stress failures caused by the large railroad cars being built today and the heavier loads which they are capable of hauling. The use of these twin ribs simplifies the machining operation used in the fabrication of the pedestal frames.
