Track fastening is an essential component of rail transportation, as it ensures the safe and reliable movement of trains along the track. Without proper track fastening, there can be issues like rail buckling, derailments, and excessive track wear.
For instance, bolted track fastening is commonly used in areas with heavy train traffic, while clip track fastening is ideal for areas with high-speed trains. It is crucial to select the appropriate track fastening system to prevent accidents, ensure passenger safety, and minimize maintenance costs.
Railway fastenings can be classified into three main types based on their structural design and method of rail fixation:
1. Elastic Rail Clip Fastening
This is the most widely used type of rail fastening. It secures the rail to the sleeper using high-strength rail clips, providing continuous elastic force. This not only fixes the rail in place but also absorbs vibrations and impacts generated during train operations. Elastic rail clip fastenings are commonly applied in high-speed railways, heavy-haul lines, and industrial tracks.

2. Bolt Fastening (Bolt and Clamp System)
Also known as the bolt-and-plate fastening, this type relies on rail bolts and rail clamps to firmly secure the rail to the sleeper. It provides strong fixation and is suitable for conventional railways or lines with moderate load requirements. While bolt fastenings are easy to install, their vibration and impact absorption capability is less pronounced compared to elastic clip systems.

3. Combined Fastening System
This system combines the advantages of both elastic rail clips and bolt fastenings. The rail clip provides elastic clamping force, while bolts and clamps enhance overall rail fixation. Combined fastenings are ideal for heavy-haul lines, bridge tracks, and high-frequency industrial railways, offering both secure rail fixation and vibration damping performance.
