How should Rail Pads be stored before use?
Rail pads should be stored in a clean, well-ventilated area away from direct sunlight, heat sources, chemical reagents, oils, and organic solvents to maintain their integrity. This prevents them from softening, becoming rigid, or degrading before installation.
Key storage guidelines
- Location: Store in a clean and ventilated place.
- Environmental factors: Keep away from direct sunlight and sources of heat. Avoid high humidity and moisture.
- Chemicals: Do not store near chemical reagents, oils, or organic solvents, and prevent any contact with these substances.
- Protection: Ensure they are protected from environmental factors that can affect their performance, such as high temperatures, which can soften rubber pads, or extreme cold, which can make them rigid.
How Do Rail Pads Stop Track Damage?
Rail Pads cut down on track damage by handling the forces that hurt rails. This part explains how they do it.
-
Soaking Up Shakes and Softening Hits
Trains make big shakes and heavy hits when they roll. Rail Pads take in these forces. This stops them from hurting rails and sleepers. For example:
Shake Control: Rail Pads calm down vibrations. This lowers stress on tracks.
Hit Reduction: They cushion rails against sleepers. This softens the impact of heavy trains.
This cushioning makes tracks last longer. It stops parts from breaking down fast.
-
Keeping Rails and Sleepers Safe
Rail Pads act like a shield. They stop rails and sleepers from rubbing together. Without them, metal rails would scrape against concrete or steel sleepers. This causes:
Surface Scrapes: Rubbing that weakens rails.
Sleeper Cracks: Too much force breaking sleepers.
Track Wobble: Uneven stress making tracks unsteady.
