The rail fastening system plays a crucial role in railway track infrastructure, serving as the core assembly that connects the rails to sleepers, whether wooden or concrete, and ensuring the safety and stability of train operations.
A well-designed fastening system not only secures the rails in position and maintains precise track gauge, but also prevents longitudinal and lateral rail movement. Additionally, it absorbs vibrations and shocks generated during train operation, thereby prolonging the service life of both the rails and sleepers.
