Abstract
A bolster of a railroad car truck is shallow and has a unique reinforcement rib which extends longitudinally of the bolster between a pair of stops which are designed to engage adjacent abutments which are carried by a transom to limit relative axial movement between the bolster and transom. The transom is generally flat and is provided with an elongated slot between the abutments to receive the reinforcement rib should the bolster, under load, deflect toward the transom a distance where the rib would contact the transom, if it were not for the slot in the transom.
