What is the difference between Rail Pad and Rail Tie Plate
Sep 23, 2025
In modern railway fastening systems, the Rail Pad and the Rail Tie Plate, although both located between the rail and the sleeper, perform distinct critical functions.
The Rail Pad, typically made from rubber, EVA, or composite materials, possesses good elasticity and damping properties. It is primarily used to absorb impacts and vibrations generated by train operation, distribute wheel loads, and protect the rail and sleeper from excessive wear and fatigue damage.
Rubber Rail Pad
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
HDPE Railway Pad
| Technical Parameter | Unit | Technical Requirement | Value |
| Density | g/cm3 | 0.95-0.98 | 0.95 |
| Tensile Strength | Mpa | ≥19 | 19 |
| Elongation | % | >80 | 150 |
| Melting Point | ℃ | 170-190 | 190 |
| Insulation Resistance | Ω | ≥1×1010 | 3.5 ×1010 |
| Hardness | A | ≥98 | 98(A) |
In contrast, the Rail Tie Plate is mostly manufactured from cast or forged steel, offering high rigidity and strength. It serves as a crucial support and positioning component between the rail and the sleeper. Its surface features bolt holes and gauge positioning grooves, allowing the rail to be securely fixed by bolts and nuts, ensuring gauge stability, and withstanding longitudinal and lateral forces. The complete installation structure is typically: Rail → Rail Pad → Rail Tie Plate → Sleeper.

Within a complete railway fastening system, these two components often work in synergy with rail clips, elastic rail clips, fishplates (rail joints), rail shoulders, and rail clamps (base plates) to collectively ensure the safety and durability of the track structure.
