Rail Pad is a core component in the track system that combines cushioning and insulation functions. In addition to load distribution, vibration damping, and noise reduction, it also isolates electrical conduction between the rail and sleeper, preventing interference or leakage in track circuit signals, thereby ensuring the normal operation of train monitoring and signaling systems. Its insulation performance must meet a volume resistivity of ≥10¹⁰ Ω·cm and a breakdown voltage of ≥20 kV, making it an indispensable functional component in electrified railways and intelligent track systems.
What industry standards do rail pads comply with?
Rail pads comply with various industry standards covering quality (ISO 9001, IRIS), environment (ISO 14001), safety (ISO 45001, Network Rail's DFR), and specific railway performance, such as European EN standards (EN 16730, EN 13146) for testing and material integrity (virgin rubber, low-temp elasticity), and national standards (RISSB's AS 1085.19 in Australia, RDSO's IRS-T-55 in India) for material specs and design, ensuring durability, vibration dampening, and track safety.
Performance & Material Requirements
Material Purity: Must use virgin natural rubber (RSS grades) or synthetic blends (SBR, PBR), avoiding recycled rubber.

| Notes | They should be stored in a clean, ventilated place. Don't be in direct sunlight, and keep away from the heat source and chemical reagent. Don't touch the oil, organic solvent, and other chemicals. Banned exposure. |
Low-Temperature Elasticity: Must retain elasticity at low temperatures (e.g., -40°C) with high elastic recovery (≥80%) to prevent brittleness and loosening.
Design & Testing: Adherence to standards for shock absorption, load capacity, vibration reduction, and resistance to environmental factors like heat and moisture.
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
