ABSTRACT:
A restraining rail mounting assembly which supports a rail adjacent to a track for maintaining the wheels of railroad cars on the track while traversing dangerous curves or any area where derailing is a potential hazard. The mounting system is comprised of a support having a tongue and oblique slot for mounting a railroad track on its side and permitting adjustment on the space between the track and the restraining rail. The mounting assembly is comprised of a plate embedded in a cement pedestal with a second support plate for locking the rail support bracket also secured in the cement pedestal. The base of the rail support bracket has diagonally opposite extensions with the extension furthest from the rail having a serrated surface and matching lock washer to securely hold the restraining rail mounting bracket. The restraining rail mounting bracket has an abutment or foot for bracing the base flange on the restraining rail and a tongue extending outward from an angled slot having a mounting hole through which a bolt can pass to secure the web of the rail to the rail support bracket. Angled slots in the support plate compensate for longitudinal forces such as expansion and contraction of the rails due to temperature changes to maintain the spacing and alignment of the restraining rail and the track.
