ABSTRACT:
A track fastener has a top plate spacedly surrounded by a frame and connected to the frame by a body of elastomer bonded to both the top plate and the frame at all surfaces at which the elastomer fills the gap between the two. The frame has hoods overhanging ribs of the elastomer which have inclined flanks covered by the elastomer as the elastomer reaches down from the gap between the hood and the rib to the top surface of the top plate lying below the receiving surface of the top plate on which the rail bears.
