Abstract
An improved railway brake shoe member characterized by longitudinally tapered sidewalls of the brake shoe that provide adaptive response to braking under conditions of mis-alignment between the brake shoe member and the tread of a railway car wheel by facilitating wear-in of the mis-aligned brake shoe, thereby assuring brake shoe/wheel tread engagement and accordingly alleviating degradation of braking efficiency and undesirable thermal inputs to the wheel flange that otherwise results from such brake shoe mis-alignment.
