ABSTRACT:
A bolster for a railway car truck having an obstacle-free cavity located below a center plate so as to more readily accommodate truck linkage members, brake apparatus and other associated mechanical components. The obstacle-free cavity is defined by a top and a bottom member, sidewalls each having an elliptical opening therein and two spaced vertically inclined lateral ribs which distribute the weight of a body of the car between the top and bottom members.
