The railroad shoulder is a prefab in concrete sleepers, either single or double, for securing elastic rail clips (mainly e-clips) within the fastening system.
Kingrail Parts can produce various railroad shoulders according to UIC, AREMA, GB, NF EN 1563(1997), DIN, JIS, BS and other standards.
Cast-in Shoulder
The cast in rail shoulder, which is an embedded part of the rail fastening system, is pressed into the concrete sleeper to fix the rail together with the E-clip. cast in rail shoulder made of cast 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 ).

Welded on Shoulder
Welded on shoulder is used in the typical position of rails, where the rail shoulders are welded to flat steel plates rather than standard tie plates. The production method of welded on shoulder is hot forging and it is manufactured according to AREA standard. The type of steel used for welded on shoulder production can be mild or medium carbon steel, depending on your specific requirements.
Special Rail Shoulder
This type of shoulder can also be made by hot forging, with rail clamp bolts and special rail clamps to fix the rail, and the material is low carbon steel or medium carbon steel.
