Rubber railroad pads play a key role in many common railway fastener systems due to their high elasticity and weather resistance.
In the SKL series fastener system, rubber pads are often used in urban subway and light rail lines. The SKL fastener system focuses on the stability and shock absorption performance of the track. The high elasticity of the rubber pads can effectively buffer the high-frequency vibrations generated by the train operation. For example, in the busy transfer station area of the subway, the trains start and stop frequently. The rubber pads can quickly absorb the impact force, reduce the rigid contact between the rails and the sleepers, avoid the fasteners from loosening due to vibration, ensure the stability of the track structure, and reduce the running noise and the impact on the surrounding environment.
The spring clip IV fastener system is also an important application scenario for rubber pads. The system is often used in ballasted track railways with speeds of 250km/h and below. The weather resistance of the rubber pad is obvious here. Whether it is hot summer or cold winter, it can maintain good elasticity and performance. On railway lines in northern regions, rubber pads will not crack in low temperatures in winter, and will continue to provide stable support for the track, ensuring that the spring bar IV fastener system can function normally and maintain a reliable connection between the rails and sleepers.
The Nabla system emphasizes the coordinated fastening effect between the fasteners and the rails and sleepers, and the high elasticity of the rubber pads plays a key role in this. The rubber pads can quickly absorb and buffer the high-frequency vibrations and shocks generated by the train, reducing the impact on the Nabla shrapnel and other components. For example, on some commuter rail lines that frequently start and stop, the use of the Nabla system with rubber pads can effectively reduce the risk of shrapnel breakage due to vibration fatigue, extend the service life of the shrapnel, ensure the system's long-lasting and stable fastening force on the rails, and ensure the stability of the track structure.
