Rail shoulder, also called rail iron shoulder, is mainly used to be cast in the concrete ties to fixate elastic rail clips. According to the shape, it can be classified into Single Stem Rail Iron Shoulder and Twin Stems Rail Iron Shoulder. Besides, based on manufacturing methods, rail shoulders can be divided into three types: casting rail shoulder, weld-on rail shoulder, and hot forging rail shoulder.
The rail shoulder is embedded in concrete at the time of casting. It is used to grip the clip effectively and provides lateral support to the rail. It acts as a semi-embedded part to fix the elastic rail clip to the base plate. Common types include Cast-in Shoulders and Weld-on Shoulders.
