Railway pads are actually anti-vibration pads for railways, usually the abbreviation of rubber pads for railway tracks. Railway pads are key components of railway structures and are used between rails and concrete sleepers. The main function of this rubber pad is to reduce the vibration and shock generated by the passing of the train, thereby protecting the railway track base and sleepers. What's more, railway pads isolate the signaling system and reduce noise (especially when used in subway rail fastening systems). Since the rubber rail pad is always exposed to the atmosphere, it has high requirements on its resistance to natural aging, cold resistance and heat resistance. Therefore, it is very important to find a professional railway pad manufacturer. Kingrail Parts is just one of these railway pad manufacturers.
Kingrail Parts railway pad is made of natural rubber, styrene butadiene rubber, HDPE, EVA, high density polyethylene, polyethylene and other materials, it is not easy to deform or break at high or low temperature. In addition, it has the following advantages:
1. Strong shock resistance, strong stability and strong wear resistance
2. Long service life and low maintenance and replacement costs
3.Railway pads are complete, suitable for most rails and sleepers
4. It has a good absorption effect on the uneven contact surface between the rail and the bracket
Railway Pad Material
We have developed a range of high performance elastic rail pads to meet stiffness requirements and various application areas - from trams to standard rail gauge railways to heavy haul railways, especially for E-rail fastening systems and SKL-type rails The HDPE material/EVA/Rubber of the fastening system, respectively, has the following characteristics.

Types of Railway Pads:
1.Rail Pads for E-type Rail Fastening System
Rail pads for E-rail fastening systems have a similar function as rail insulators, insulating the rail above them to reduce vibration and structure noise. Rubber rail pads, e-type clips, rail insulators/insulation gauge blocks, rail shoulders/embedded parts together constitute a complete set of E-type rail fastening system.
2. Rail Pads for SKL Rail Fastening System
Rail pads in the SKL Rail Fastening System work with SKL clips, screw spikes, plastic pins and tie plates, etc. The stiffness of the rubber rail pads significantly increases the elasticity of the rail superstructure, thereby reducing noise.
3. Concrete Sleeper Rubber Pad
