A rail fastening system is a set of components used to securely connect steel rails to railway sleepers. Generally, a railway fastening system is expected to provide a reliable connection while maintaining a simple structure, along with features such as elasticity, shock absorption, and electrical insulation.
Components Of SKL Clip Rail Fastening System
The SKL railway fastening system consists of components including SKL rail clips, rail pads, screw spikes, tie plates, washers, plastic dowels, track bolts, and nuts. Commonly used sizes of the SKL fastening system include SKL 12, SKL 14, and SKL 3.
