How does the Rail Fastening System work

Rail fastening systems usually use a variety of fasteners, such as bolts, nuts, fasteners, etc., to secure the rail to the tie. These fasteners provide a strong fastening force, either physically (such as threaded connections) or chemically (such as adhesives), ensuring that the rail does not displace or loosen while the train is moving.

In order to absorb the vibration and impact force generated when the train is running, the track fastening system usually contains elastic elements, such as spring washers, rubber MATS, etc. These elastic elements can reduce the impact of vibration on the track and train, improve ride comfort, and extend the service life of the track system.

To ensure that fasteners do not become loose due to vibration, track fastening systems often include locking mechanisms. These mechanisms may include lock washers, lock nuts, etc., which prevent the nut from loosening on its own under vibration. In addition, some advanced track fastening systems also use self-locking or pre-tightening technology to ensure that fasteners maintain a stable fastening force during long-term use.

Rail fastening systems require regular inspection, adjustment and maintenance. This includes checking the tightness of the fasteners, the wear of the elastic elements, and the overall stability of the track. When necessary, fasteners need to be tightened or replaced to ensure the safety and stability of the track system.

With the continuous development of technology, some modern track fastening systems begin to use intelligent monitoring technology. These systems use sensors and wireless communication technology to monitor the status of the track fastening system in real time, including fastening force of fasteners and deformation of elastic components. When an abnormal situation is detected, the system automatically alarms and prompts the maintenance personnel to handle it accordingly.
