↵Rail Anchor Fastening System
The GNEE Elastic Rail Anchor represents the third-generation evolution in rail restraint systems, engineered to overcome the fundamental limitations of traditional anchors. Unlike rigid or frictional anchors, our patented elastic design provides dynamic, self-adjusting restraint that maintains optimal clamping force across the entire temperature range from -50°C to +70°C. Through intelligent material selection and precision geometry, we've developed a system that eliminates rail "breathing" while preventing excessive stress buildup in continuous welded rail (CWR) tracks.
