摘要：
A railway tie plate has at least one rib to locate a railway rail and two arches under which parts of rail clips can be driven parallel to the rib. It can be made by deformation of a conventional tie plate designed for use with fastening devices for holding the rail on to the tie plate other than rail clips which are driven parallel to the rail.
