Abstract
In a freight car truck assembly, an insert for converting a substantially flat, inclined, bolster pocket back wall into a pair of inclined surfaces for biasing a pair of split wedges laterally outwardly against side walls of the bolster pocket to create a space between the pair of split wedges. The insert is provided with a centrally located fin which projects into the space between the split wedges and engages against a side frame friction surface to control the location of the insert in the bolster pocket through frictional interference as the fin rubs against the friction surface. The insert can be loosely mounted in the bolster pocket without any need for welding the insert in place.
