1. Method of resiliently fastening railway rails, comprising the fastening of the rail in a normal manner on a support unit and the interposing of at least one resilient intermediate element between the rail support unit and any appropriate substrate, this or these intermediate element(s) having a resilience determined so as to be able to offer a good antivibratory effect and appropriate resistance to subsidence under a given load, characterised in that it comprises in addition the insertion, between the rail support unit and the substrate, of at least a second resilient intermediate element having a different resilience, called second resilience, which is determined so as to be able to present a good antivibratory effect under a second given load, smaller than the aforesaid first load, and in that, when the rail is under the aforesaid first load, all the resilient intermediate elements are stressed, whereas, when the rail is under the aforesaid second load, only the second resilient intermediate element or elements is/are stressed. |
