Rubber rail pads are elastic polyurethane mats that are interposed between railway sleepers and steel rails. Their function of rubber rail pad is to reduce fatigue cracking of the concrete ties, which is believed to be driven by impact and vibration from the passing train. The starting stiffness of a rubber rail pad is designed to not be high so that their relative deformation under the elastic rail clip toe loads is greatly substantial. By this means, it can guarantee the rubber rail pad maintaining in close contact with the rail despite of any vertical movements of the latter. In addition, the reason why rubber rail pads made up of rubber or plastic is to dampen the shocks of vibration of a passing train.

When designing rail pads for railway track systems, there are several factors to consider to ensure optimal performance and durability. These factors include the type of material used, the shape and size of the rail pad, and the environmental conditions in which the rail pad will be used.
Choosing the right rail pad for a specific application depends on several factors, including the speed of the trains, the weight of the loads, and the environmental conditions. The rail pad should be designed to provide adequate cushioning and vibration reduction while also maintaining the stability of the rail system. For example, a high-speed railway system may require a rail pad made of natural rubber, while a system that carries heavy loads may require a rail pad made of composite materials.
Best practices for rail pad replacement include following manufacturer recommendations for material and size, ensuring proper installation and alignment, and conducting performance testing after replacement. Proper installation and alignment are critical for ensuring that the rail pads perform as expected and provide the necessary cushioning and vibration reduction.
