Rail Pad Types From GNEE RAIL
Sep 22, 2025
GNEE RAIL specializes in producing rail fastening parts include Rail Pads. Keep the rail stable, to preclude and buffer impact, increase friction and reduce vibration, rail EVA pad lies between the rails and base plates. It can be made of HDPE, EVA, rubber, and EPDM materials. Main rail pads are made for E type rail fastening system and SKL type rail fastening system.

GNEE Rail Pad Features
It is thought that the rail pads have 2 main functions: they diminish shock or impact loads by providing compliance, and they reduce (by isolation and perhaps by damping) resonant vibrations created in the concrete ties (lowest resonant frequency about 200 Hz) and accommodate vibration deflections in the rail sections between the ties (about 0.12mm amplitude, 1000 Hz).
- Noise Suppression
- Improved Passenger Comfort
- Extended Track Life
- Extended Ballast Life
