RUBBER RAIL PADS

Rubber rail pads are widely used to reduce fatigue cracking of the concrete ties caused by the vibration of passing train. When the train’s wheel is over the pad, the latter’s stiffness must be high to prevent large movements which can result in the metal spring becoming loose. Such a load-deflection characteristic can be obtained by introducing grooves in the rubber pads.
