Freight railroads haul some of the heaviest loads in the transport industry—gigantic trains carrying bulk materials, containers, and industrial goods across long distances. These activities impose tremendous pressure on the rails and fastening systems, especially in impact areas such as joints, switches, and curves.
For long-term safety, reliability, and cost-effectiveness, heavy-haul operators require fastening systems that are extreme in their capability. SAFE’s Type VI Fastening System is tailor-made to satisfy these requirements—delivering high strength, increased fatigue life, and low maintenance requirements.
What is the Type VI Fastening System?
The Type VI Fastening System is an extreme-capability rail fastening system for heavy-haul and freight railroads. It anchors the rail securely to the sleeper, maintaining gauge and alignment under extreme axle loads of more than 30 tons. All parts—elastic clips, tie plates, baseplates, and pads—are engineered for stiffness, strength, and reliability under repeated dynamic loading. This results in a fastening system that provides track stability, suppresses vibration, and prolongs the life of both the track and infrastructure.
Engineering Built for Heavy-Haul Rail
Handling Extreme Axle Loads
Heavy-haul rail trains exert enormous vertical and lateral forces on the rails. Type VI employs high-tensile steel clips and specially designed baseplates that preserve structure under compression. The pieces are resistant to deformation and loosening, hence the track remains stable even with strenuous freight service.
Fatigue and Impact Resistance
At high-impact sites such as turnouts and crossings, fastening systems experience quick wear. Type VI system employs impact-absorbing resilient pads and elastic pads that distribute loads uniformly and damp vibrations. It minimizes metal fatigue and prolongs component life, reducing mechanical failure chances.
Long-Term Durability
All the components undergo a fully automatic manufacturing process, including heat treatment, quenching, tempering, and corrosion-resistant surface coating. This guarantees accurate dimensions and consistent quality. The result is a fastening system that will function correctly with drastic changes in temperature, humidity, and heavy mechanical stress.
Key Features and Benefits
Stable and Rigid Structure
Type VI’s rigid design ensures safe rail anchorage with minimal movement. Cast shoulders and high-strength fasteners keep the rail securely in place, maintaining precise geometry throughout the railroad’s life, critical for freight service on long, high-tonnage routes.
Advanced Anti-Fatigue Design
With optimized materials and polyurethane pad production, SAFE‘s Type VI system reduces stress transfer to the sleeper. Elastic and tie pads dissipate vibration and energy, protecting both the supporting structure and fastening assembly.
Low Maintenance and Cost Efficiency
Economy is equivalent to durability. Fatigue and corrosion resistance of the Type VI system lead to reduced inspections, longer service life, and considerably lower life-cycle costs to freight operators.

Additionally, in 2022, SAFE provided high-performance railway rubber level crossings to China Railway 11th Bureau Group for the Wuhan–Huangshi Intercity Railway Project, demonstrating the company’s engineering excellence and commitment to quality.
Future-Proofing Freight Infrastructure
Enabling Global Freight Growth
As global freight volumes increase, the infrastructure must also be able to accommodate heavier, faster, and more frequent trains. The Type VI system can offer the reliability and structural resilience necessary to accommodate the growth, making capacity additions by operators possible without compromising safety.
Sustainability Through Longevity
Sustainability means durability. Through reduced replacement periods and maintenance operations, the Type VI system minimizes environmental impact and maximizes operating efficiency. SAFE’s computer-aided production gives minimal wastage and reproducible product quality—making the rail infrastructure more sustainable.
