What is the rail shoulder?
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.
Cast-in rail shoulder
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. 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).

Weld-on shoulder
The weld-on shoulder is used at the typical position of rail where the rail shoulder is weld on flat steel plate rather than the standard railroad tie plate. The weld-on shoulder is produced by hot forging, according to AREA standard. The materials for weld-on shoulders production can be low or mid carbon steel, based on the customer's requirements.
For the record: The rail cast iron shoulders can be welded on to longer length steel sleeper sections or bearers, for locations where fabrication of switch and crossing layouts where vertical rail geometry is employed. The railway shoulder's ability to be welded in the specific position as dictated by the layout design, this makes it particularly useful and cost effective in this case.
