ZRF is a unique innovative solution designed by Rahee to overcome the shortcomings of the present fastening system used by railways on bridges. Rahee’s design of ZRF assembly on Steel Channel Sleeper or H-beams meets the requirement of IRPWM (i.e. Rail free fastening). The Rahee design uses Elastic Rail Clip Mk-III, which is same as used on standard Track on the approaches at the Bridges in Indian Railways.Provides no restraint on longitudinal movement of Rail.Provides rigid lateral support to Rail for stability, correct gauge and alignment.Provides vertical stability to Rail by use of Elastic Fastening.
