A rail pad is inserted in between the rail and baseplate or sleeper. Rail pad is introduced to the railway fastening system because of its resilience or viscoelasticity which can be implemented in the intervention of fatigue cracking of sleepers. The dynamic stress from the wheel or rail impact from both regular and irregular movements is attenuated.
How does the railroad pad protect the railway track from impacts?
Rail pads protect tracks from impacts by acting as elastic buffers between the steel rail and concrete sleeper, absorbing shock, dampening vibrations, distributing wheel loads over a larger area, and reducing noise and abrasion, which extends infrastructure life. They cushion the rail, preventing direct metal-on-concrete contact, minimizing stress, and allowing for slight movements that absorb impact energy from heavy, fast-moving trains.
How is the dynamic stiffness of railway pads controlled?
Material optimization: Select EPDM/TPE/EVA or composite materials based on environmental conditions and line grade.
Structure customization: Precisely regulate stiffness and damping characteristics through thickness, groove, and composite layer design.
Condition adaptation: Design compensation mechanisms for variables such as temperature, frequency, and axle load.
System matching: Ensure compatibility with fasteners, rails, and sleeper stiffness to form an integrated solution.
The rail pad laid under the rail is used to guarantee
- The load distribution covering a larger surface area
- Reducing load concentration and usage fatigue stress
- Even contact area between the rail and supporting components
- Reducing noise and structural vibrations
- Sealing function between the top support and rail bottom
- Reducing rail wearing and relevant supporting components
As a professional rail fastener manufacturer, GNEE RAIL can produce various types of rubber rail pads with different materials, such as natural rubber, EVA, HDPE and so on. In railway fastening system, rubber rail pads are often installed between the rail tracks and the concrete railway sleepers.
