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.

[ What is claimed is:] [1.] A support assembly (3) for a railway rail (1) having along its length a head and a web integral with said head and depending downwardly from said head, said support assembly comprising respective pluralities of rail supporting means (31, 32, 33, 34) disposed at mutually opposed locations on both sides of said rail for resiliently suspending said rail above a track foundation (2) underlying said rail, said plurality of supporting means on each side of said rail being spaced from one another longitudinally of said rail and engaging said rail at discrete locations along the rail, said mutually opposed supporting means being constructed for applying a force to said rail at each of said discrete locations such that a transverse component of said force is applied to said web of said rail and that an upward component of said force supporting the weight of said rail is applied to the underside of said head of said rail, and said supporting means further including fixing means (41, 51/52; 53h, 60; 701, 71/72; 63; 80, 82; 90, 91; 100, 101) establishing positions of said mutually opposed supporting means relative to one another whereby to enable said supporting means to exert on the opposite sides of said rail at each of said discrete locations a predetermined clamping load for imparting to said support assembly a desired resistance to longitudinal creep of said rail through said support assembly, wherein said mutually opposed rail supporting means comprise first and second brackets (31, 32) and first and second elastic members (33, 34), each of said first and second brackets having a bearing part (312, 322) and a base part (311, 321), said bearing part of each of said first and second brackets being located adjacent to one or the other side of said rail (1) when said support assembly (3) is in use and said base part of each of said first and second brackets being located on an upper surface of said track foundation (2), each said first elastic member (33) being located between a respective said first bracket (31) and said rail and each said second elastic member (34) being located between said rail (1) and a respective said second bracket (32), when said support assembly is in use, and said mutually opposed rail supporting means further comprising means (41, 51, 517; 53, 60; 701, 71, 72, 73; 701, 71, 72, 74; 41f, 52; 311j, 321j, 381j, 382j; 80 to 82; 90 to 94; 100 to 103;) for maintaining said predetermined clamping load, and wherein said first and second brackets (31, 32) are held in place on said track foundation (2) by said fixing means, at least part of which are located within the confines of respective recesses provided therefor in respective ones of said base parts (311, 321) of said first and second brackets.
