Rail pads are commonly used in which railway fastening systems？
Oct 09, 2025
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 pads are indispensable key components within rail fittings system components. Their core function is to absorb vibrations and impact loads generated by train operation through their material properties, reduce direct friction between steel rails and sleepers, thereby protecting the track structure, extending service life, and enhancing the stability and safety of train operation.
Application of rail pad in rail fastening system
E Clip Rail Fastening System
The E-type fastening system is one of the most widely used railway fastening systems, used primarily for concrete sleepers. It is widely used in ordinary railways and heavy-load railways and is suitable for standard tracks of high-speed railways.
