Railway pads always play a key role in rail fastener system. It's a bedding device between the rail track and the railway sleeper (or railroad tie), which ensures the railway safely and stably operates by providing cushion and support.
GNEE RAILWAY RAILWAY is equipped with rail pad production lines for 130sets of machines, for the whole process of injection, refining rubber, sulfuration, moulding and inspection, etc. We own the most engineers for rail pad development, design, production and inspection, with annual production capacity reaching up to 2000, 000 pieces. What's more, rail pads for high speed rail lines are our featured products, including both the elastic rubber plates and height adjustment pads.
Rail pads can vary in thickness, typically ranging from 4.5mm to 25mm, with thicker pads (10mm to 60mm) used for heavy-duty applications and thinner ones (4.5mm to 6mm) for lighter loads. The specific thickness is chosen based on factors like train speed and weight, as a thicker pad provides more cushioning and noise reduction, while a thinner one can be used where maintaining a lower track profile is important.
Common thickness ranges
Thin pads: 4.5mm to 6mm, often used for lighter loads where a lower track profile is desired.
Standard pads: 5mm to 25mm, commonly used for a wide range of applications to protect sleepers and reduce vibration.
Thick pads: 10mm to 60mm, used for high-impact, heavy-haul, and high-speed lines to maximize cushioning, vibration control, and longevity.
Factors influencing thickness choice
Factors influencing thickness choice
Train weight and speed: Heavier and faster trains require thicker pads to distribute load and absorb more vibration.
Track type: Different systems may call for different thicknesses. For example, pads for concrete sleepers are often different from those used with timber ties.
Environmental conditions: Extreme temperatures can influence the choice of material and thickness to ensure durability.
GNEE RAILWAY RAILWAY offers track pads in various thicknesses, allowing selection based on different rail types and track conditions, along with installation guidance to ensure track stability and longevity.
