Typical Service Life of Rail Fastening Systems
Mar 23, 2025
Service Life
| Component | Service Life (Approximate) | Notes |
|---|---|---|
| Elastic Clips (SKL Clips) | 15–25 years | Depends on material quality, traffic volume, and maintenance. |
| Base Plates | 20–30 years | Durable materials like cast iron or composite extend lifespan. |
| Rail Pads | 10–15 years | Rubber or polyurethane pads may need replacement sooner due to wear. |
| Insulators | 10–20 years | Subject to degradation from environmental exposure. |
| Tension Washers | 15–25 years | High-quality steel washers last longer but may require periodic checks. |
Economic Impact of Service Life
Longer Service Life: Reduces the frequency of replacements and maintenance, lowering lifecycle costs.
Shorter Service Life: Increases maintenance and replacement costs, leading to higher operational expenses.
