Similarities between GB 60KG Heavy Rail and BS 113A Heavy Rail
In terms of usage: Both are mainly used for the laying of railway tracks, providing running tracks for locomotives and vehicles, bearing the pressure of the wheels, and transmitting the force to the sleepers. At the same time, they provide a continuous, smooth and low-resistance rolling surface for the wheels.
Basic structure: Both adopt an I-shaped cross-section with good bending resistance performance, which is composed of three parts: the rail head, the rail web and the rail bottom. This structure helps the rail to better bear the forces from all aspects.
Comparative Advantages of GB 60KG Heavy Rail
Stronger load-bearing capacity: The theoretical weight of the GB 60KG heavy rail is 60.64kg/m, which is greater than that of the BS 113A heavy rail (56.398kg/m). Moreover, its dimensions such as rail height and bottom width are larger, making it more advantageous in bearing the load of trains. It can meet the operation requirements of high-speed trains and large-volume freight trains, and is suitable for railway main lines, heavy-haul railways and high-speed railways, etc.
Higher stability: The GB 60KG heavy rail has a relatively high rail height and a wide bottom width. After the track is laid, it has a larger contact area with the sleepers and the roadbed, resulting in better stability. It can effectively reduce the vibration and deformation generated during the operation of the train, providing a smoother running environment for the train.
Better wear resistance: In terms of materials, the GB 60KG heavy rail commonly uses materials such as U71Mn. This kind of material has been verified through long-term practice and has good wear resistance. During long-term use, it can reduce the wear of the rail surface, extend the service life of the rail, and reduce the maintenance cost.
Wider application range: Due to its high strength, load-bearing capacity and stability, the GB 60KG heavy rail is not only suitable for ordinary railway transportation, but also widely used in high-speed railways and heavy-haul railways and other lines with high requirements for tracks. In contrast, the BS 113A heavy rail is mainly used in scenarios such as mine roadways and factory workshop transportation, and its application in high-speed railways and heavy-haul railways is relatively limited.
