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.

Abstract: A direct fixation track rail fastener includes a first clip shoulder and a second clip shoulder each having a clip tunnel formed therein. Each clip tunnel is formed in part by a plurality of clip contact faces defining a first prong contact line and a second prong contact line for a prong of a rail clip. The configuration of multiple line contacts prevents undesired displacement of a rail clip during service.

Abstract: 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.

Abstract: A spring anchor assembly for fastening track rail includes a spring anchor having a hook end, a tail end, and a middle section. An insulator is fitted upon the spring anchor and includes a plurality of rib walls extending fore and aft between a first outer insulator wall and a second outer insulator wall. The outer insulator walls form downward depending wall sections extending, respectively, from termination locations of the rib walls to the lower peripheral edges. A channel is formed between the wall sections and receives the middle section, contacted by the plurality of rib walls at the termination locations. The insulator insulates the spring anchor to limit leaking electrical currents from the track rail to ground.

The eccentrics include axially extending external teeth interlocked with axially extending slots within the positioner bores. In an aspect, the eccentrics are dual eccentrics each including tooth and slot interlocking arrangements with another eccentric or the frame.

Abstract: A fastening system for track rail includes a track rail fastener positionable upon a pedestal mount, and including a top plate, a frame, and an overmolded jacket. The system further includes a lateral positioner having an eccentric structured to contact a pedestal mount, and a locating pin extending through the fastener body and the eccentric to couple a lateral location of the fastener body to an angular orientation of the eccentric, such that rotating the eccentric varies a lateral location of the fastener body. A frame in the fastener body includes a plurality of vertically extending finger walls for lateral and rotational stability, with the overmolded jacket extending between the finger walls and the top plate.

Abstract: A track-mounting assembly secures a longitudinally extending rail direction to a substrate and has a frame fixed to the substrate and a track plate fitted in the frame. A vertically throughgoing aperture of the frame has an inner edge formed by a longitudinally extending gauge surface directed transversely toward a field side of the assembly and a transversely oppositely directed and longitudinally extending field surface. The track plate carries the rail and has an outer edge is itself formed by a longitudinally extending field surface spacedly transversely confronting the gauge surface of the aperture and a longitudinally extending gauge surface spacedly transversely confronting the field surface of the aperture. The field surface of the track plate is of substantially greater area than the gauge surface of the aperture. An elastomeric mass fills between the frame and the track plate.

Abstract: A fastening mechanism for coupling track rail to a substrate includes a fastener body formed by a metallic base and an overmolded non-metallic coating. Metallic pillars are coupled with the fastener body, and define bores for receiving anchors held fast within a substrate. The coating encases the metallic base and extends peripherally around the metallic pillars to position vibration-attenuating non-metallic material between the metallic base and the metallic pillars.

Abstract: An assembly for mounting a longitudinally extending track on a substrate has a track plate having a top face adapted to carry the track and formed unitarily below the top face with a plurality of longitudinally extending tongues, a base plate at least partially below the track plate, adapted to be anchored to the substrate, horizontally surrounding the tongues of the track plate, and formed with a plurality of longitudinally extending tongues transversely spaced from, longitudinally interleaved with, and horizontally at least partially level with the tongues of the track plate. The track plate and base plate are wholly out of direct engagement with and spaced vertically and/or horizontally from each other. An elastic jacket or liner is engaged between the plates and between the tongues of the track plate and the tongues of the base plate.

Abstract: An assembly for securing at least one rail to a substrate has a longitudinally extending rail plate extending across and secured underneath the rail and having a pair of opposite ends. Respective end restraints at the ends of the rail plate each have a jaw fixed to the respective end of the rail plate and each formed with a vertically throughgoing passage. A respective rigid anchor hood is fixed to the substrate in each of the passages with an outer surface of the anchor hood spaced inward from an inner surface of the respective passage and forming an annular space therewith. A respective rubber bumper mass fills each of these spaces so that forces transverse to the rail are transmitted through the bumpers to the anchor hoods.
