Abstract
A rail fastening clip which secures a rail to a mounting or support structure which allows some flexing of the rail. The clip is constructed of a hard durable material and is provided with a fulcrum point to permit a small amount of longitudinal flexion of the rail. The clip is also provided with resilient inserts to permit the fastening clip to allow the rail to expand, thus compensating for longitudinal forces. The fastening clip is constructed for use with existing rail fastening base assemblies.
