Rail Fastener System

What is Rail Fastening System?

Rail fastening system is composed of main parts of the rail structure for connecting steel rails with sleepers, also known as rail fastening parts. Rail fastening system functions by fixing the rail on the sleeper, maintain the gauge and prevent the rail from moving longitudinally and laterally relative to sleeper. And it provides enough elastics to make up for deficency of conceret sleeper. So rail fastening system must be satisfied with reqiurments of strength, durability and certain elasticity. It keeps reliable connection of steel rail and sleeper. The fastening system has developed to be easy to install and disassemble with less accessories in recent years.

Rail Fastening System Types: E-clip Fastening, Pandrol Fast Clip Fastening, Tension Clamp Fastening, Bolt Clamp Fastening, Tack Joint and Chairs Fastening, and Steel Spring Keyed rail in Chair Fastening
