ABSTRACT:
An insert for a railroad brake shoe having a support plate engageable complementally with a portion of the shoe back. Shoulders are provided for preventing the lateral and longitudinal displacement of the insert relative to the brake head assembly. A guide is cantilevered from one side of the support plate and so configured to generally complementally fit the flange of the wheel, thereby to guide the shoe into aligned contact with the wheel tread when the brake is applied.
