A railway rail support assembly (3), for resiliently suspending a railway rail (1) above a track foundation (2) it 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), 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.
Un système (3) de support de rail permettant de placer d'une manière élastique un rail (1) de chemin de fer au-dessus des fondations (2) de la voie ferrée à des emplacements distincts le long du rail (1), a des moyens de support de rail par lesquels s'exerce une force de serrage prédéterminée sur ledit rail (1) pour que le système (3) ait la résistance souhaitée au fluage longitudinal du rail (1). Lorsque le système (3) est en service, les moyens de support (3) du rail sont fixés, de préférence, à une surface supérieure sensiblement horizontale des fondations (2) de la voie ferrée. Un tel système (3) peut comporter des première et seconde brides (31, 32) et des premier et second éléments élastiques (33, 34). Chacune des première et seconde brides (31, 32) a une partie d'appui (312, 322) et une partie de base (311, 321), la partie d'appui (312, 322) jouxtant les deux côtés du rail (1) quand le système (3) est utilisé et que la partie de base (311, 321) se trouve sur une surface supérieure desdites fondations (2) de la voie ferrée. Le premier élément élastique (33) se trouve entre la première bride (31) et le rail (1) et le second élément élastique (34) se trouve entre le rail (1) et la seconde bride (32), quand le système (3) est en service. Le système (3) comprend, en outre, un moyen pour maintenir ladite charge de serrage prédéterminée.
