RNY Rail Fastening System

The RNY rail fastening system is a highly popular, spring-blade elastic fixing mechanism engineered primarily to secure 115RE steel rails onto concrete sleepers. Widely trusted and deployed across railway networks in North America, Mexico, and South America, the RNY system is a global industry standard. Rail operators select it for its exceptional track durability, cost-effectiveness, and superior structural noise and vibration mitigation.

At Signum Rail Fasteners China, we manufacture and supply complete RNY assemblies and individual replacement components. Every part is precision-engineered at our advanced manufacturing facility to match your exact technical drawings, rail dimensions, and international railway compliance standards.

Key Benefits of the RNY Spring Blade System

· High Elastic Clamping Force: Ensures reliable track gauge holding power and resists long-term rail creep under heavy freight axle loads.

· Cost-Efficient Track Maintenance: The simplified structural design lowers initial procurement costs and reduces ongoing track maintenance overhead.

· Vibration & Noise Control: High-performance elastic properties dampen track vibration and minimize structural noise propagation.

· Electrical Track Isolation: Integrated high-performance insulation elements preserve the electrical integrity of signaling and track circuits.

Core RNY Fastening Assembly Components

Our complete, standard RNY rail fastening sets feature high-tensile components working in tandem to protect concrete sleeper integrity:

· RNY Elastic Plates (Spring Blades): Fabricated from premium spring steel to apply consistent clamping force directly to the rail base.

· Square Elastic Plates: Provide secondary structural stabilization and absorb shifting mechanical loads under dynamic traffic.

· SL Bolts & Track Bolts: Heavy-duty, high-tensile threaded fasteners (typically 7/8*201 spec) complete with heavy hex nuts and flat washers for secure anchoring.

· NY Nylon Washers & Insulators: Deliver critical electrical isolation between the 115RE rail and the concrete sleeper to eliminate current leakage.

· U-2 Rail Pads: Elastic under-rail mats that distribute extreme axle weight uniformly, protecting concrete sleepers from premature wear and cracking.
