Can other Rail Fastenings replace Rail Rubber Pads?
No, other rail fastenings cannot replace rail rubber pads because they serve different, complementary functions within the fastening system. Rail rubber pads are elastic cushions that absorb shock and vibration, protect the tie, and provide electrical insulation, while other components like tie plates are rigid and are responsible for distributing the rail's load and securing the rail to the sleeper. A complete rail fastening system, especially with concrete sleepers, requires both elastic pads and rigid components to function correctly.
Rail rubber pad functions
- Shock and vibration absorption: Reduces impact from passing trains, which protects the sleeper and sub-grade.
- Tie protection: Prevents the tie from being abraded or damaged by the rail's movement.
- Electrical insulation: Isolates the rail from the sleeper, which is crucial for signal systems.
- Noise reduction: Minimizes noise pollution by dampening vibrations.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Components they work with
- Tie plates: Rigid metal plates that sit directly on the sleeper. Their primary role is to distribute the rail's load and provide a base for the rail and other fastening components.
- Sleepers: The beams (wood or concrete) that lie perpendicular to the rails, anchoring the track.
- Clips and other fasteners: These are the parts that physically hold the rail to the sleeper. The elasticity of the rubber pad works with the rigidity of these components to maintain tension and stability.
Why they are not interchangeable
- Replacing a rail rubber pad with a rigid component would eliminate the crucial shock absorption, vibration damping, and noise reduction benefits.
- Without the pad, the direct contact between the rigid tie plate and the sleeper would increase wear and tear and could lead to faster deterioration of the sleeper.
- An improper replacement could lead to a fastening system that is too stiff, causing damage to the track and sub-grade, or could fail to provide the necessary electrical insulation for signaling.
