The E-type rail clip is a core elastic locking component in the railway fastening system, named after its "E"-shaped open structure. It is primarily installed by side-mounting into the pre-embedded iron seat grooves of sleepers, utilizing its own elastic deformation to generate continuous clamping force, thereby securing the rail to the sleeper or tie plate. It is a key component in ensuring the geometric stability of the track. Its design requires no bolts for fixation, enabling easy installation and removal, and it is compatible with various sleeper types, such as wooden sleepers and concrete sleepers. It is widely used in rail fixation scenarios across various rail transit lines.
