Adjustable rail fastening assembly
Assembly (10) for fastening a railway rail (1), comprising a lower platen (11) provided with through holes (111) for anchoring the lower platen to ground (40) by means of anchoring means (15), an upper platen (12) superposable on the lower platen for supporting the rail (1), and a pair of rail fastening clips (142) for fastening the rail to the upper platen (12). The lower and upper platens comprise a pair of corresponding first holes (112, 121) distinct from the through holes (111), for removably securing the upper platen (12) to the lower platen (11) by first fastening means (16) independent of the ground anchoring means (15). The upper platen (12) and the rail fastening clips (142) comprise a pair of corresponding second holes (122, 144) distinct from the first holes and from the through holes, for securing the rail fastening clips (142) to the upper platen (12) by means of second independent fastening means (17). The first holes (121) of the upper platen (12) have oblong shape with a longer axis oriented transverse to the rail (1) so as to allow for lateral adjustment of the upper platen (12) relative to the lower platen (11).

Tie plate centering and inserting machine
A tie plate inserter assembly on a track mounted machine is provided that is configured to ensure appropriate location of a tie plate and a tie relative to a rail of a railway. The assembly includes a frame supported, at least indirectly, on a chassis of the machine and having a tie plate clamp assembly that includes a self-centering mechanism that centers the tie plate relative to a longitudinal centerline the tie. The tie plate clamp assembly has a first clamp plate and a second clamp plate configured to clamp together to hold the tie plate. The tie clamp assembly also has first and second clamp plates configured to clamp together to hold the tie in place. The assembly may additionally include a tie clamp assembly that can be actuated to center the tie relative to a reference point on the frame.

EXTRUDED PVC GLASS FIBER REINFORCED RAILROAD TIE WITH ENHANCED THERMAL AND MECHANICAL STABILITY
An extruded PVC railroad tie with glass fiber reinforcement contains glass fibers and clumps of pelletized glass fibers that enhance friction of all surfaces that are not coated with a cap stock. Parallel spaced apart interior walls enhance structural integrity. Two interior walls provide structures for threaded channels to threadedly and frictionally engage bolts for securing rail connection hardware. Interior compartments provide empty space for air and ballast. Air in the compartments moderates thermal expansion. A protective cap stock covers one or more sides, such as the exterior top and side surfaces of the tie. The bottom surface, which may be substantially devoid of a cap stock, exhibits roughness to grip and frictionally engage underlying ballast.

Track rail fastener structured for displacement restraint
A direct fixation track rail fastener includes a rail plate having a first restraint hole and a second restraint hole upon opposite lateral sides of a rail support surface. The fastener also includes a frame including a first vertical protrusion and a second vertical protrusion received through the first restraint hole and the second restraint hole. A non-metallic cushion extends between the rail plate and the frame and vertically upward to surround the first vertical protrusion and the second vertical protrusion within the first restraint hole and the second restraint hole, respectively. The configuration assists in limiting displacement of the rail plate and frame relative to one another.

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.
