Rail Shoulder Applications:
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.
