Features
Fundamental Role in Track Systems
Tie plates serve as critical interface components that:
-
Transfer dynamic wheel loads from rails to sleepers
-
Maintain precise track geometry (gauge, alignment, and cant)
-
Protect wooden sleepers from rail foot abrasion
-
Provide uniform load distribution to prevent ballast degradation
Comparative Advantages
Steel vs. Composite Tie Plates:
| Parameter | Steel Plates | Composite Plates |
|---|---|---|
| Load Capacity | Higher (50kN+) | Moderate (35kN) |
| Corrosion Resistance | Requires coating | Inherent |
| Electrical Insulation | Conductive | Excellent |
| Temperature Range | -40°C to +70°C | -50°C to +80°C |
| Lifecycle Cost | Lower long-term | Higher initial cost |
Maintenance Optimization
