Track rail fastening system and rail cushion for same

A rail cushion for positioning laterally between fastener assemblies in a track rail fastening system comprising:

• a one-piece cushion body including a first vertical side, a second vertical side, and a center section, a first full-length pad, and a second full-length pad, together forming, upon the first vertical side, a continuous planar face;
• the first full-length pad and the second full-length pad including, upon the second vertical side, a first full-length lateral face and a second full-length lateral face, respectively, defining a first rail cushioning plane;
• and
• the center section including, upon the second vertical side, a pin field formed by a plurality of deformable pins confined in distribution between the first full-length pad and the second full-length pad, such that a lateral extent of the pin field is limited to between the first full-length lateral face and the second full-length lateral face, and the plurality of deformable pins including respective pin end surfaces defining a second rail cushioning plane spaced vertically outward of the first rail cushioning plane.

A rail cushion comprising:

• a one-piece cushion body including a first pad and a second pad including a first lateral face and a second lateral face, respectively, each extending in a fore-aft direction from a back pad edge to a front pad edge, and laterally from an inboard edge to an outboard edge of the respective first pad or second pad;
• a pin recess extends fore-aft from the back pad edge to the front pad edge and laterally between the inboard edges, and the cushion body further includes a pin field within the pin recess;
• the first lateral face and the second lateral face defining a first rail cushioning plane;
• the pin field is formed by a lower load pin set defining a second rail cushioning plane, and a higher load pin set defining a third rail cushioning plane;
• and
• the one-piece cushion body is deformable between a rest configuration where the first, second, and third rail cushioning planes are spaced, and a loaded configuration where the first, second, and third rail cushioning planes are coplanar.
