The Functions of Rail Shoulder

1. Load Distribution: Rail shoulders help distribute the vertical loads from the rails and passing trains evenly onto the sleepers. This prevents excessive stress on individual sleepers and the underlying trackbed, enhancing the overall stability of the track.

2. Cushioning and Protection: Rail shoulders serve as a cushion between the rail and the sleeper, reducing direct contact and preventing damage due to impact and vibration. This can extend the lifespan of both the rail and the sleeper.

3. Vibration Damping: The use of rail shoulders can help dampen vibrations generated by passing trains, leading to reduced noise levels and a more comfortable environment for nearby residents.

4. Rail Alignment: Rail shoulders also play a role in maintaining proper rail alignment, ensuring that the rails stay in position and maintain the correct gauge (distance between the rails).

5. Installation: Rail shoulders are designed to be easily installed on the sleepers. They are typically secured using fasteners like bolts or clips, and their design allows for proper positioning and alignment with the rail base.
