Abstract
A track rail fastening system includes a rail cushion positionable laterally between a first fastener assembly and a second fastener assembly. The rail cushion includes a first full-length pad and a second full-length pad, and a pin field formed by a plurality of deformable pins. The first full-length pad and the second full-length pad define a first rail cushioning plane. The deformable pins in the pin field define a second rail cushioning plane. The cushion is deformable between a rest configuration where the cushioning planes are spaced, and a loaded configuration where the cushioning planes are co-planar. Primary, lower load deformable pins are configured to deflect such that under sufficient load both the primary, lower load deformable pins, and secondary, higher load pins engage an underlying substrate.
