Rail fastening system is used to link steel rail with the sleeper parts (or other types of rail parts), it also known as the intermediate coupling parts. Its role is to make the steel rail fixed on the rail sleeper, at the same time maintain track spacing and prevent steel rail lateral movement relative to the rail sleeper.
As for the components of SKL railway fastening system, including SKL rail clips, rail pad, screw spike, tie plate, washer, plastic dowel, track bolt and nuts, etc. common sizes of SKL rail fastening system include SKL 12, SKL 14 and SKL 3 rail fastening system.
