What are the dimensions of rail pads?
Dec 19, 2025
A rail pad, also named rail rubber plate, is usually used between tie plates and sleepers or between rails and tie plate. The rail pad is made of elastic polyurethane mat and usually used on concrete sleepers. The rail pad can protect the concrete sleeper from abrasion and impaction, and it can also decrease the vibration from the passing train. It is believed that rail pad functions in two ways: diminish shock and distribute load.
What are the dimensions of rail pads?
Rail pad dimensions vary widely by application (railway track vs. crane), material, and rail profile, but generally range from 5mm to 25mm in thickness, with widths tailored to the specific rail foot (e.g., 170-220mm for some crane pads), and lengths up to 12 meters or more, often customized, to provide cushioning, electrical insulation, and vibration damping.
Key Dimension Factors:
Thickness: Common ranges are 4.5mm-10mm for standard rail, but can go up to 25mm for heavy loads; crane pads might be 7mm (center) with side thickness varying.
Width: Determined by the rail's foot width plus a margin; examples include 170mm, 190mm, 200mm, 220mm for crane pads.
Length: Often supplied in long strips (e.g., 12m, 6m) or cut to size for specific baseplate lengths, with lengths like 3.8m, 4.2m, 4.5m also seen.
The Function of Rail Pad
- Distribute the load that the wheels pushed on the rails with a larger elastic surface.
- Reduce the noise and diminish the shock that trains hitting on the rails and improve the comfort of the passengers.
- The elasticity of rail pad can decrease the vibration that rails pass on the fasteners and the roadbed.
- The use of rail pad can decrease the abrasion of rails and prolong the service life of rail track and other rail fasteners.
