Non Separated Rail Fastening Systems(Direct Holding Fastening System)

Rail Pad
Side-post Insulator
Spring Clip
Cast Iron Shoulders
It is known as Direct Holding Fastening System.
Divided into two types: Elastic (mainly using Spring Clips and Spring Blades) and Rigid ( mainly using Rail Clamps and Rail Spikes).
The fastening system joins the steel rail with cast-in rail shoulders, in a way, the steel rail and the sleepers are directly connected.
The railway clips/clamps are fixed directly onto the cast-in shoulders, instead of railroad tie plates/shoulder plates ( used in separated rail fastening systems).
Compatible models of Spring Clips: E1809, E1817, E1819, E20 series and etc.
