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.
