E20 Rail Clip

The buckling parts of elastic fasteners are mainly spring bars, which generate buckling pressure on the track through bending and twisting deformation of the spring bars, effectively ensuring the reliable connection between the rails for a long time, maintaining the integrity of the track as much as possible, and preventing the rails from moving longitudinally and transversely relative to the sleepers.
