ABSTRACT:
A resilient mounting for a rail on a concrete sleeper which has a flexible liner between the ground or base flange of the rail and the sleeper and a mounting clamp on opposite sides of the base flange forming a flexible nylon or polyacetal resin rail restrainer which overlies and engages the base flange and the sleeper. A bowed spring plate overlies the rail restrainer and overhangs beyond the edge of the restrainer above the base flange of the rail, with a clamping bolt extending through the bowed spring plate and rail restrainer. The spring plate is bowed into an arcuate configuration in a plane parallel to the longitudinal axis of the rail, at least at the edge adjacent the rail, and become flattened during tightening of the clamping bolt drawing the spring plate into compressing engagement with the rail restrainer.
