Railway rail fastening apparatus, for suspending a railway rail (1) at discrete locations along its length above a rail foundation (2), comprises two rail suspending assemblies (4A, 4B) located when in use one on each side of the rail (1) . Each assembly (4A, 4B) comprises an elastic member (6) for supporting the head of the rail (1) on one side thereof and a bracket (7) for applying a lateral clamping force to the elastic member (6) ) . The rail suspending assembly (4A) on one side of the rail (1) is located such that the centre line (CLA)of the assembly (4A) is offset with respect to that (CLB) of the rail suspending assembly (4B) on the other side of the rail (1) by x mm along the longitudinal axis of the rail (1) , where x is 50>=x>0 mm.
L'invention concerne un appareil d'attache pour rail de chemin de fer, pour suspendre un rail de chemin de fer (1) en des emplacements distincts sur toute sa longueur au-dessus du massif de fondation de rail (2), appareil comportant deux ensembles de suspension de rail (4A, 4B) se trouvant, lorsqu'ils sont utilisés, de chaque côté du rail (1). Chaque ensemble (4A, 4B) comporte un organe élastique (6) pour supporter le champignon du rail (1) d'un côté de celui-ci et un support (7) pour exercer une force de serrage latérale sur l'organe élastique (6). L'ensemble de suspension de rail (4A) d'un côté du rail (1) est situé de manière à ce que l'axe (CLA) de l'ensemble (4A) soit décalé par rapport à celui (CLB) de l'ensemble de suspension de rail (4B) de l'autre côté du rail (1) de x mm le long de l'axe longitudinal du rail (1), où 50=x>0 mm.
