Rail Rubber Pads, also called guard rail plates, which are set between the frog guard rail and the turnout sleeper to provide a firm connection condition for the guard rail and the running rail (basic rail) to ensure the width of the guard rail rim groove and driving safety. The guard rail pad is one of the important parts of the track, and its function is to ensure that the vehicle smoothly passes through the special area such as the switch part or the bridge without derailment accidents.
