What are the ways to fix railway tracks

Rail fixing is a key link to ensure the safe and stable operation of trains. The following are several common ways to fix rails:

1. Spike fixing method
Railway spikes are the most widely used method for fixing railway tracks. By driving spikes into the wooden or concrete sleepers under the track, the rails and sleepers are tightly combined to achieve the fixing effect. The advantages of spike fixing are that it is simple, fast and low-cost, but it also has certain disadvantages, such as being easily affected by weather, environmental factors, and may become loose or rusty.

2. Fastener fixing method
Fasteners are a more advanced way to fix rails, which usually consist of a set of metal clamps and buckles. This fixing method uses fasteners to tightly fix the rails to the sleepers, and has high stability and reliability. Compared with spike fixing, fastener fixing can better adapt to the thermal expansion and contraction of the rails and reduce safety hazards caused by temperature changes. However, the cost of fastener fixing is relatively high, and regular inspection and maintenance are required.

3. Fixed rail puller

The fixed rail puller is a professional rail fixing device that fixes the rail to the sleeper through pre-tightening force to ensure its stability and safety. The fixed rail puller is usually installed on both sides of the track, and the pre-tightening force is applied to the rail by adjusting the bolts to make it fit tightly on the sleeper. This method can not only prevent the rail from moving during the operation of the train, but also effectively reduce noise and vibration, and improve the comfort of passengers.

The advantages of the fixed rail puller are mainly as follows:

(1). High stability: By applying pre-tightening force, the rail and the sleeper are tightly combined to ensure the stability of the track.

(2). Strong safety: It can effectively reduce the movement and deformation of the track, thereby reducing the safety hazards during the operation of the train.

(3). Vibration reduction and noise reduction: The fixed rail puller can significantly reduce the noise and vibration during the operation of the train and improve the comfort of passengers.

However, the fixed rail puller also has some disadvantages, such as high cost and complicated installation and disassembly process. In addition, since the fixed rail puller needs regular inspection and maintenance, a lot of manpower and material resources need to be invested in the process of use.

In general, different rail fixing methods have their own advantages and disadvantages, and the choice of which method should be determined according to the specific usage scenario and needs. In the future, with the continuous advancement and development of science and technology, we look forward to the emergence of more efficient, safer and more economical rail fixing technology to contribute to the development of the railway transportation industry.
