What is the role of rail fasteners?

1. Fix the rails

Ensure stable position: firmly fix the rails to the sleepers or track plates to prevent the rails from being displaced horizontally, longitudinally or vertically when the train passes. Whether the train is accelerating, decelerating or running at a constant speed, the fasteners can ensure that the rails are always in the correct position and provide a stable travel path for the train.

Resist external interference: bear the weight of the train and various dynamic forces generated during operation, such as impact force, vibration force, etc. At the same time, it can also resist the wind force in the natural environment, thermal expansion and contraction caused by temperature changes, etc., to ensure that the rails will not loosen or shift due to external forces.

2. Maintain the track gauge

Precisely control the spacing: strictly control the distance between the two rails to keep it within the standard track gauge range. This is crucial for the safe operation of the train, as changes in track gauge may cause the train to derail. Fasteners ensure the accuracy and stability of track gauge through precise design and installation.

Adapt to different working conditions: Under different working conditions such as train turning, uphill and downhill, the fasteners can be adjusted according to the stress of the rails to keep the gauge unchanged. At the same time, in the long-term use process, even if the rails are worn or deformed to a certain extent, the fasteners can also play a certain adjustment role to maintain the rationality of the gauge.

3. Disperse pressure

Uniformly transfer the load: Evenly disperse the huge pressure transmitted by the train through the rails to the sleepers or track plates. This can avoid the concentration of pressure in a certain local area, reduce the damage to the track foundation, and extend the service life of the track.

Reduce local damage: The elasticity and buffering effect of the fasteners can reduce the direct impact of pressure on the rails and sleepers, and reduce the risk of local damage such as wear and fracture of the rails and sleepers. At the same time, it also helps to reduce the frequency of maintenance and replacement of the track and reduce the cost of railway operation.

4. Enhance the integrity of the track

Connect various components: Connect the rails, sleepers, track plates and other track components tightly together to form an integrated track structure. This integrity can improve the strength and stability of the track, so that the track can better withstand the running load of the train.

Coordinate deformation: During the operation of the train, various parts of the track may deform to varying degrees. Fasteners can coordinate these deformations, keep the deformation of the track within a reasonable range, and ensure the smooth running of the train.
