    摘要： An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.

    摘要： A railway rail support assembly (3), for resiliently suspending a railway rail (1) above a track foundation (2) at discrete locations along the rail (1), has rail supporting means through which a predetermined clamping load is exerted on the said rail (1) such that the assembly (3) has a desired resistance to longitudinal creep therethrough of the rail (1). The rail supporting means are preferably attached, when the assembly (3) is in use, to an approximately horizontal upper surface of the said track foundation (2). Such an assembly (3) may be provided by first and second brackets (31, 32) and first and second elastic members (33, 34). Each of the said first and second brackets (31, 32) has a bearing part (312, 322) and a base part (311, 321) (311, 321), the bearing part (312, 322) being located adjacent to either sides of the rail (1) when the assembly (3) is in use and the base part (311, 321) being located on an upper surface of the said track foundation (2). The first elastic member (33) is located between the first bracket (31) and the rail (1) and the second elastic member (34) is located between the rail (1) and the second bracket (32), when the assembly (3) is in use. The assembly (3) further comprises means for maintaining the said predetermined clamping load.

    摘要： A base plate includes a lateral support section and a lateral contact surface which delimits a supporting area formed on a top side of the base plate for a foot of a rail. A through-hole leading from the top side to the underside of the support section is formed into an edge area of the support section abutting the lateral contact surface. The through-hole has a basic shape which is angular in cross-section. The surface of the edge area meets with the contact surface in an upper marginal edge. A lateral surface of the through-hole assigned to the contact surface at least over a partial area of its height changes into an inclined surface which rises in the direction of the upper marginal edge of the contact surface and ends at the surface of the edge area.
