Description

Rail clip is a component of railway fastening systems. It is used to fix the railroad track to the underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper. One extensively used type of rail clip is an elastic rail clip made of hot-pressed spring steel. Its energy produced at elastic deformation can alleviate the vibration and shock when trains move.

TECHNICAL SUPPORT

Gauge lock clip, mostly used in Argentina, Bolivia. The material used for gauge lock clip is 60Si2MnA or 38Si7.
