In the railway system, the stability of the track is related to the safety of train operation. The E-type fastener system plays a key role and can be found on all kinds of railway lines.
High-speed railways
On high-speed railways, trains run at high speeds and have extremely high requirements for track stability. With its strong buckling pressure, the E-type fastener system can firmly fix the rails on the sleepers, resist the high-frequency vibration and strong centrifugal force generated by high-speed running, and prevent the displacement of the rails. For example, on high-speed railway lines running at 350km/h, the E-type spring bar can provide stable buckling pressure, maintain accurate track gauge, ensure safe and smooth operation of trains, and reduce the frequency of track maintenance.
Heavy-load railways
Heavy-load railways carry large volumes and large axle loads, and the tracks are under tremendous pressure. The E-type fastener system uses high-strength components, such as special E-type spring bars and solid embedded iron seats, which can withstand repeated rolling by heavy-load trains. On heavy-load railways with axle weights of more than 30 tons, it can effectively prevent rail creep and sleeper damage, ensuring long-term and efficient operation of the railway.
Ordinary trunk railways
Ordinary trunk railways are the basic network of railway transportation. The E-type fastener system meets the daily passenger and freight transportation needs with moderate cost and reliable performance. It has a simple structure and is easy to install and maintain. It can reduce construction and maintenance costs while ensuring the stability of the track. It is a common choice for ordinary railway lines.
Urban rail transit
In urban rail transit, such as subways and light rails, the E-type fastener system not only ensures the stability of the track, but also takes into account the need for noise reduction. Rubber pads and optimized E-type elastic bars can effectively absorb the vibration of train operation, reduce the impact of noise on the surrounding environment, and adapt to the complex underground and ground line conditions in the city.
Special terrain railways
In special terrain railways such as mountainous areas, there are a large number of ramps and curves on the line, and the track force is complex. The E-type fastener system adjusts the component parameters to enhance the lateral constraint and longitudinal anti-climbing ability of the rails, ensure the safe passage of trains through complex sections, and ensure the normal operation of special terrain railways.
