The rail fastening system is the main part forming a connecting with both rail and sleeper to ensure the reliability and stability of rail track. The elasticity of non-ballasted track basically depends on rail fastening system, the accuracy of non-ballasted also depends on the fastening system to adjust and maintain. As you can see, the importance for high-speed railway and the direct impact for transportation of the fastening system are obvious.
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.
Fasten The Steel Rail and Sleeper Together
A rail fastening system is consist of rail clip, rail spike, rail anchor, tie plate or other fastenings, they work together and make the whole fastening system stable and solid, which provide a safe running environment for the vehicles.
Maintain the Rail Gauge
The fastening system can keep the rail gauge and prevent the vertical and horizontal movement of steel rails by connection it tightly to the sleepers.
Ensure the Safety of Railway and Vehicles
The safety of railway and the vehicle is closely related with the stability of steel rail, rail joint and rail fastening system ensures the stability of rail track.
Main Types of Rail Fastening System
KPO Rail Fastening System
The KPO fastening system is a wedge-shaped fastening commonly used on wooden and steel sleepers, applicable to ordinary railways, light rails, and low-speed railways.
