ABSTRACT:
A rail anchorage arrangement for fastening a rail, the anchorage comprises: a support structure; a body of weldable material welded to the upper surface of the support structure at a weld between the body and the support structure extending at least partially around the body and along at least 20% of the length of the body from said upper surface of the support structure; a screw-threaded hole extending into the body of weldable material from the end thereof remote from said upper surface of the support structure; a screw-threaded member screwed into the screw-threaded hole so as to be made fast in the body of weldable material, this member not being threaded into the support structure; a rail anchorage having a hole receiving the screw-threaded member so that the screw-threaded member makes fast the rail anchorage against said upper surface of the support structure to secure a rail to the support structure; the body having a lateral dimension which is at least 40% greater than the outer dimension of the thread of the screw-threaded member so that the body and the weld serve to resist substantially all lateral forces between the rail anchorage and the support structure. By the provision of the body of weldable material the screw-threaded member does not have to be of weldable material and hence can be a high strength material.
