Product Description
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 shoulder, both of which are used for the fixing of elastic rail clips. The casting shoulders as the embedded part of the railway fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail.
