The rail shoulders are cast on the concrete sleepers and are used to fix the elastic rail clips. There are two types of rail shoulders to choose from, pre embedded rail shoulders and welded rail shoulders, both of which are used to hold elastic rail clips.
Gnee Rail can produce various rail shoulders according to UIC, AREMA, GB, NF EN 1563(1997), DIN, JIS, BS and other standards.

As it is named, rail cast iron shoulder is made by casting from iron and compressed in concrete sleepers. And its available material is 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).
As for weld-on rail shoulder, it is produced by hot forging according to AREA standard, and it is used in places where standard ties cannot be easily used and should be used on flat steel tie plate. Moreover, it allows users to fabricate rail retaining units on both steel sleepers and steel base plates.
The weld on shoulder fastening makes the fabrication of rail retaining units on both steel sleepers and steel base plates possible when the E style of elastic rail clips are used for the fasting of the rail.
Even though the rail cast in shoulder are usually pressed in the concrete sleeper, it also can be welded on to longer length steel sleeper sections or bearers for use in the fabrication of switch and crossing layouts where vertical rail geometry is employed.
The welding ability of rail shoulders in particular position which is dictated by layout design makes rail shoulders much useful and cost effective.
Rail shoulder accessories used for specific rail sections should be adopted according to design criteria in order to achieve the correct elastic clip toe loading . And certain rail shoulders with milled weld area faces are provided to achieve a better weld integrity.
