Grooved Rail
Grooved rail, characterized by a central groove along its length, is a specialized rail solution engineered to enhance operational safety and seamless integration with road surfaces. This innovative design prevents derailments while enabling smooth coexistence of rail systems with other road users, making it a cornerstone in modern urban and industrial transit.
Why Do We Call Grooved Rails the “King of Rails”?
Grooved rails are dubbed the “king of rails” primarily due to their extraordinarily high manufacturing difficulty. The irregular groove structure on the railhead makes the rolling process extremely complex. They have stringent precision requirements for aspects such as straightness, torsion, and the shape of the rail lip.
Additionally, construction welding demands advanced techniques like flash welding, which involves high technical content. These high technical thresholds and strict production standards make grooved rails stand out as the “king of rails” in the industry.
Grooved Rail Types
These grooved rail models are designed for reliability, with specifications tailored to medium-traffic transit needs.
| type of Rail | Weight kg/m | Head width mm | Height mm | Height mm | Web mm |
| 59R2(Ri59N) | 58.20 | 113.00 | 180.00 | 180.00 | 12.00 |
| 60R2(Ri60N) | 59.75 | 113.00 | 180.00 | 180.00 | 12.00 |
Applications of Grooved Rail
Grooved rails are widely used in scenarios where rail and road need to coordinate, adapting to different traffic and environmental needs.
Urban Tram Corridors
Ideal for modern tram systems, supporting steady city traffic on dedicated or shared tracks in urban environments.
Shared-Traffic Intersections
Designed for safe tram and vehicle movement in mixed-use roads, often seen in global city streetcar networks.
Historic City Streets
Blends modern rail lines into heritage areas while carefully preserving historic streetscapes and minimizing overall urban visual impact.
Industrial Transport Routes
Supports efficient rail logistics within ports, factories, and industrial zones, reducing road congestion and noise.
Advantages of Grooved Rail
