ABSTRACT:
Friction shoes are preassembled in each end of a railcar truck bolster by providing openings in the bolster and in the shoes and passing a restraining member through the openings at each bolster end and tensioning and securing the restraining members so as to hold the shoes within respective pockets in the bolster. The shoes and pockets are further provided with cooperating anti-ejection features to prevent ejection of shoes after installation.
