A trainline support bracket and a fastener for mounting the bracket to a rail car coupler assembly which includes spaced, downwardly extending mounting extensions having aligned bores therein, with the bracket including a pair of upwardly extending arms, spaced apart a distance to be positioned directly outside of the mounting extension. The openings in each of the upwardly extending arms are aligned with bores in the extensions. A headed bolt extends through the aligned bores and openings to attach the bracket to the coupler assembly. A nut is threaded on the bolt. The specific improvement of the present invention is a retainer which is attached to the bolt and bracket and prevents removal of the bolt from the aligned openings and bores even if the nut is removed from the bolt.
