Concrete sleepers are increasing their popularity as part of contemporary rail systems because they are long-lasting, strong, and cheap in the long run. The E2007 Fastening System seeks to emulate these qualities by offering track gauge, weather stress resistance, heavy axle loads, and tight curve radii.
The E2007 Fastening System is a high-tech rail fastening system engineered expressly for concrete sleeper track. SFFST developed this system, and it promises safe rail attachment, long-lasting stability, and predictable performance over a wide range of operating conditions. As the need for long-term, low-maintenance railway infrastructure becomes stronger, the E2007 Fastening System has established a balance between engineering and heavy-duty materials to provide the maximum possible rail safety levels.
Key Components of the E2007 Fastening System
Rail Clips: W-Tension Clamps and E-Clips
The E2007 Fastening System utilizes E-Clips or W-Tension Clamps, based on track demands. The clips impose a constant toe load and hold the rail in place with controlled, limited deflection. This minimizes lateral and longitudinal rail movement with dynamic loading for long-term track stability. These clips are produced by SFFST with high precision in all-automated production lines, which provides consistent performance and dimensional tolerance to every unit.
Rail Pads and Insulators
The gauge insulators and rail pads play a double function: mechanical shielding and vibration damping. Polyurethane pads absorb shocks, lower noise levels, and shield the sleepers from abrasion, while the insulators offer the electrical insulation necessary for safe rail running. SFFST manufactures the parts using high-technology computerized injection molding and pouring techniques, which make them uniform and resistant.
Anchoring Elements
Concrete sleepers require heavy-duty anchoring, which is achieved through embedded dowels, spikes, bolts, and nuts. SFFST’s fasteners are manufactured under stringent standards of accuracy to yield superior pull-out resistance and long-term stability against even severe loads.
Design Principles Behind the System
Emphasis on Stability and Durability
The E2007 Fastening System is in accordance with international standards stringently. A test series is employed to ascertain the suitability of fastening systems for railway track use, i.e., type approval of finished fastening systems. Its development enables each piece to withstand repeated mechanical stress with minimum deformation or deterioration.
Vibration and Noise Reduction Features
With rugged tie pads of high quality and elastic materials, the E2007 Fastening System keeps track noise levels down and minimizes vibration transferred on the track. This is especially important in mass transit systems, where noise control is especially important.
Resistance to Environmental Stress
All of the constituents are coated with anti-corrosion compounds and are designed to operate in extreme weather conditions, humid environments, and chemical exposure. A test report should include at least the following details: installation type and installation weather at the time of installation;—a need we always meet with our rigorous internal quality control processes.
Benefits for Concrete Sleeper Applications
Suitability with High-Speed Rail
The E2007 Fastening System has also been successfully used on high-speed rail networks like the Wuhan-Guangzhou High-Speed Railway, operating speeds above 300 km/h. Its elastic elements offer gauge stability and lower dynamic stress on the rails.
Low Maintenance and Long-Term Cost-Efficiency
High-precision assembly and robust material lower inspection and repair frequency, lowering life-cycle cost. Relative to conventional rigid fastenings, the resilient design of E2007 Fastening System lowers wear rate and extends operational life.
Heavy-Haul and Freight Adaptability
The system also performs well at high axle loads, such as in Fenghong and Jingshen Railways, where it maintained more than 130,000 fastening sets. Mechanical strength also makes it fit for application in coal or mineral-transferring tracks or large freight volumes.
How E2007 Fastening System Is Different from Conventional Systems
- Elastic Design: In contrast to rigid fastenings, E2007 Fastening System provides micro-movements without weakening structural integrity.
- Modularity: The components are simple to assemble or swap using simple tools, allowing quicker maintenance.
- Compliance with Standards: Complete compliance with EN 13481-1:2012 and BS EN 13481-2:2022, for worldwide reliability.
Uses in Railway Infrastructure
- Urban Transit: Urban transit lines such as Chengdu Metro Line 17 are encouraged by their low noise and vibration-dampening features.
- High-Speed Rail: Provides track stability at high speeds, as demonstrated through intercity projects such as the Wuhan-Huangshi Railway.
- Freight and Heavy-Haul Lines: Withstands tremendous axle loads, permitting bulk carriage efficiently.
