Cast-in Rail Shoulders are prefabricated pieces in concrete sleepers, either single or double, used to secure elastic rails within a fastening system, mainly electronic fastenings.
Cast iron shoulders are cast in iron, pre-embedded in concrete sleepers and used together with elastic clips to fix the rails.
Weld-on Shoulders are designed for use in special trackwork locations where standard tie plates cannot be used. Applications include switches, scales, steel structures, and maintenance facilities.
Generally used on flat steel plates, these shoulders are beveled to facilitate welding. They are designed to provide optimum lateral resistance and maximum clip-toe load. Weld-on shoulders can be designed for all rail sizes and are readily available in commonly used standard rail sizes.
