Rail fastening system, also known as rail fasteners, is components that connect steel rails and railway sleepers. It plays an important role in ensuring track stability and reliability.
The E-clip fastening system is a widely used rail fastening system that is characterized by its simplicity, reliability, and ease of installation. It is designed to provide excellent resistance to both vertical and lateral forces, making it an ideal choice for a wide range of railway applications.

Rail Shoulder
The casting shoulders as the embedded part of the rail way fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail. The cast in shoulder is made by casting from iron, such as, GB/T 1348-1988, NF EN 1563(1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293(1985) or BS EN 1563(1997).
