Features
The Rail fastening system is a crucial component of railway tracks that ensures the stability and safety of the tracks and enables the smooth and safe operation of trains.
Fixed rail
Ensure that the rail is in a stable position on the sleeper to prevent it from moving horizontally or vertically.
Transfer train load
The load generated during the train operation is effectively transferred to the sleeper and roadbed.

Type and classification
Classified by fastening form of fastener
Bolted fastening method: the fastener is fixed together with the rail and tie by bolts.
Bolt-free fastening: Other methods (such as welding, fasteners, etc.) are used to fix the fasteners together with the rails and sleepers.
Classified by connection to ballast
Separate fastener: there is an iron cushion plate, and the fastener firmly fixes the rail on the iron cushion plate, and the iron cushion plate is connected with the sleeper or track plate through the anchoring bolt.
Undivided fastener: there is generally no iron cushion plate, and the fastener directly fixes the rail to the sleeper or track plate.
Classified by type of fastener
Elastic bar fastener: The elastic bar is used as the fastener, and the rail is fixed by the deformation of the elastic bar.
Shrapnel fastener: The use of shrapnel as a fastener, through the deformation of the shrapnel to fix the rail.
By providing the necessary stiffness and stability, the track geometry is maintained to ensure that the train can run on the intended route.
Reduce the impact and vibration of the train during operation and improve the ride comfort.
Performance requirement
Intensity
It can withstand various loads generated during train operation, including static loads and dynamic loads.
Durability
It can maintain stable performance in a variety of harsh environmental conditions for a long time, and is not easy to rust, wear and other phenomena.
Stability
It can ensure the stable position of the rail on the sleeper, preventing it from moving horizontally or vertically.
Elasticity
It can provide appropriate elasticity, reduce the impact and vibration of the train during operation, and improve the ride comfort.
