The rail fastening system is an important part of the railroad track structure composed of various rail fasteners (OTM materials). Its main function is to firmly fix the rails on the sleepers or track plates to ensure the stability of the rails.
Rail clip, or called elastic rail clip, is used to fasten steel rails to the underlying tie plate. Through bending and distortion, rail clip can put pressure on the rail, which prevents longitudinal movement of the rail, either from changes in temperature or through vibration. In general, rail clips are made of forged spring steel produced by hot forging process. Because of the most uniform microstructure, the forged rail clips are considered to be better than other metal forming process.
