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.

A mechanism for coupling a track rail to a substrate includes a rail plate and a base plate, where the rail plate surrounds the base plate. An overmolded coating is formed of a non-metallic material and encases the rail plate and the base plate. Related methodology is disclosed.

A bonded, direct fixation fastener as supportive structure for a rail on a railroad bed comprising: a substantially rectangular rail plate, wherein the rail plate has a generally horizontal center portion having a lower face and an upper face and wherein the rail plate defines an outer perimeter having a face defining a first angle to the railroad bed, the rail plate having attachment means to attach to the rail; a substantially rectangular bottom member defines an inner perimeter having a face defining a second angle to the railroad bed; and a substantially rectangular elastomeric portion disposed between, and bonded to each of, the outer perimeter and face of the rail plate and the inner perimeter and face of the bottom member.

The invention relates to a guide plate for laterally guiding a rail in a rail attachment point formed on a railroad tie, wherein the guide plate has a top side having a support surface for supporting a spring element, an underside, by way of which the guide plate is supported on the railroad tie during use, a support segment having a support surface, by way of which the guide plate is supported, during use, on a shoulder provided on the railroad tie, and possesses a guide segment which is formed opposite to the support segment, and on which a guide surface is present, on which a rail is laterally guided during use. In order to counteract twisting of the rail and concomitantly the risk of the occurrence of track warping at high outdoor temperatures when using such a guide plate in a rail attachment point, a latch projection is formed in lateral end segments of the guide surface, in each instance, projecting away from the guide surface in the longitudinal direction of the guide plate, which is provided for the purpose of engaging, during use, under the longitudinal side of the rail that is assigned to the guide surface, in each instance, wherein the distance between the latch projections amounts to at least 60% of the width of the guide surface.

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.

A bonded fastener for a railway rail comprising: top and bottom generally horizontal plates bonded and separated by an insulating material wherein the top plate defines a rail bed; a plurality of clip housings wherein each clip housing houses part of a hold-down clip for attaching the rail to the bonded fastener; a plurality of anchor assembly areas wherein each anchor assembly area defines an opening through the bonded fastener for receiving an attachment device for attaching the fastener to a supporting surface; and one or more generally vertical barriers comprising part of the bonded fastener. Further, a first generally horizontal barrier may extend from the bonded fastener underneath each of the clip housings, and a second generally horizontal barrier may extend from the rail bed underneath the rail on each side of the bonded fastener.
