Performance advantages of Fast rail fastener system

As an important part of railway infrastructure construction, the Fast rail fastener system has been widely used in various railway lines around the world with its excellent performance advantages. ​

Strong buckling pressure and stable track gauge retention force

The spring bar design of the Fast system is unique. After installation and pre-tightening, it can generate stable and strong buckling pressure, tightly buckle the bottom of the rail, effectively prevent the horizontal displacement of the rail, and provide solid guarantee for maintaining accurate track gauge. This strong buckling pressure enables the track structure to remain stable when facing the huge lateral force generated by high-speed trains, greatly reducing the risk of abnormal displacement and overturning of the rails, and ensuring safe and smooth operation of the train.

Excellent elastic buffering performance

The rubber pads equipped with the Fast rail fastener system have excellent elastic properties. When the train passes by at lightning speed, strong vibration and impact will occur between the wheels and the rails. At this time, the rubber pads act like efficient shock absorbers, quickly absorbing and evenly dispersing these energies, greatly reducing the impact damage to the sleepers and the roadbed. Moreover, the elastic strips themselves have good elastic deformation ability, which can flexibly adapt to the expansion and contraction deformation of the rails caused by temperature changes, frequent fluctuations in train loads and other factors, ensuring that the track is always in a stable state, effectively extending the service life of various track components. ​

Reliable anti-loosening performance​

The Fast railway fastener system fully considers the anti-loosening problem in its design. The special connection structure and high-precision manufacturing process adopted by it make the various components fit closely together, effectively reducing the possibility of fasteners loosening due to train running vibration. Some Fast systems are also equipped with anti-loosening components such as self-locking nuts, which further enhances the anti-loosening reliability of the system. In heavy-duty railway operations, the train has high axle weight and large transportation volume, and the anti-loosening performance requirements of fasteners are extremely strict. With its reliable anti-loosening design, the Fast system can withstand the repeated rolling and impact of heavy-duty trains, effectively ensuring the long-term stability and smoothness of the line, reducing the line maintenance work caused by loose fasteners, and reducing operating costs.​

Excellent durability and low maintenance requirements​

The components of the Fast fastener system are made of high-quality materials, and have excellent fatigue and corrosion resistance after strict quality control and advanced surface treatment technology. Under the influence of long-term train loads and complex natural environments, it can still maintain stable performance, greatly extending the service life of fasteners. Due to its reasonable structural design and reliable performance, it has low maintenance requirements in daily operations. Only regular simple inspections are required to ensure the normal operation of the system. This reduces the manpower and material costs of railway operation and maintenance to a certain extent, and improves the economic benefits of railway operations.
