Fasteners: The "super belt" between the rail and the sleeper, without it, the train will shake!

When the train runs, why don't the rails deviate from left to right and run back and forth? It all depends on a small and inconspicuous part-fasteners!

It is the "super belt shock absorber" between the rail and the sleeper. It is small in size and has a large effect. It is the "invisible guardian" of the track.

The core mission of the fastener: "lock" the rail on the sleeper

The positioning of the fastener is very clear-the exclusive connector connecting the rail and sleeper, the core is to do 4 things, each of which is the key:1. Fixed rails: Like a belt, fasten the rails to the sleepers to prevent the rails from moving vertically and horizontally, and ensure that the track spacing remains unchanged;2. Provide elasticity: it comes with elastic components such as rubber cushions to further buffer the impact force, vibration and noise of the train;3. Adapt to deformation: It can adapt to the thermal expansion and contraction of the rail, the slight settlement of the roadbed, and the pressure is always buckled, neither loose nor tight;4. Insulation and anti-corrosion: It has its own insulation performance to avoid short circuit of track circuit, and at the same time, it is resistant to wind and rain, not easy to corrode, and has a long life.

Summarize the importance of fasteners in one sentence: the more stable the fastener, the smoother the track; The stronger the fastener, the safer the train. Although it is small, it is the key to the smooth operation of the track!
