摘要:
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.
