Abstract
Disclosed is an end stabilized backing plate for an extended length brake shoe for use in a railway braking system. The backing plate includes an elongated main portion extending along a longitudinal axis. This main portion has a front face, a back face, a first end portion and an opposed second end portion. A first and second pair of tab members are provided on each of the first and second end portions. These tab members extend in a substantially perpendicular direction with respect to the main body and function to stabilize the end portions of the extended length brake shoe which extend beyond the length of a brake head and reduce and/or eliminate cracking of these end portions of the brake shoe. A method of stabilizing end portions of an extended length brake shoe is also disclosed.
