Rail E Clip Fastening System
The Railway E-Clip is a spring steel fastener designed for concrete sleeper tracks. Its asymmetrical geometry generates consistent clamping force that secures rails while absorbing dynamic train loads. Heat-treated for high fatigue resistance, this clip maintains toe load without loosening under vibration. Installation requires a hydraulic applicator for uniform force application. Used globally on high-speed, freight, and metro lines, the E-Clip eliminates routine maintenance and ensures long-term track geometry stability.
