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, this shoulder is pre-embedded in concrete sleepers and used together with elastic clips to fix the rails.
Weld-on shoulders are designed to be used in special trackwork locations that do not permit the use of the standard tie plates. Switches, scales, steel structures, and maintenance facilities are just some of the applications of this steel shoulder. Generally used on a flat steel plate, these shoulders are beveled to facilitate welding. Weld-on shoulders 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 the commonly used standard rail sizes.
