RUBBER PAD FOR RAILS
A rubber pad intended to be arranged between a sleeper of a track and a rail of the track is described. The pad has a flat portion with a width substantially the same as a width of the sleeper; the flat portion comprises a plurality of holes.
HIGH RESILIENT DIRECT FIXATION FASTENER IN STANDARD FOOTPRINT
A bonded, direct fixation fastener as a supportive structure for a rail on a railroad bed comprising a top member or plate having a center portion having an upper face and a lower face; the top plate defining first and second wall sections each defining an outer perimeter having an outer face defining a lower face section and an upper face section; wherein a first angle between the lower face section and a horizontal surface of the railroad bed is lower than a second angle between the upper face section and the horizontal surface of the railroad bed; a bottom plate or member having first and second anchoring sides connected by first and second elements; wherein the bottom plate or member defines an opening; wherein the bottom plate has first and second wall members each having an interior face; and an elastomeric or rubber portion disposed between the top plate and the bottom plate.
Track rail fastening system and rail cushion for same
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.
