Rail e Clip Fastening System
Railway E Clips are resilient fasteners forged from spring steel rod into a three-legged E-shaped profile, designed to secure rails within cast-in shoulders through elastic deformation. These clips generate sustained clamping force by deflecting during installation, absorbing dynamic loads from passing trains while maintaining consistent toe pressure. The closed-loop geometry ensures uniform stress distribution across all legs, preventing localized fatigue.
