Rail shoulder is cast in the concrete rail ties to fix the elastic rail clips. There are two types of rail shoulders available: the cast-in shoulder and the weld-on rail shoulder, both of which are used for the fixing of elastic rail clips.

• Material and Manufacturing Process The Pre-embedded Iron Base is usually made of high-quality cast iron or steel, providing the necessary strength and durability to withstand forces exerted by trains and maintain railway system integrity. Precision casting or forging ensures product accuracy.
• Installation and Application Installed within concrete sleepers during the pouring process. Once set, it provides a stable platform for attaching elastic fasteners, securing the rail to the sleeper and ensuring track alignment and stability.
• Importance in Railway Safety Acts as a vital foundation to prevent track movements and deformations, which is crucial for preventing accidents and ensuring reliable transportation.
