The cross-section shape of the rail is an I-shaped cross-section with the best bending resistance, which is composed of three parts: rail head, rail waist and rail bottom.
Rail type:
According to the shape, they are divided into I-shaped rails, U-shaped rails and arc-shaped rails.
I-shaped steel is suitable for small and medium-sized railway lines.
U-shaped steel is suitable for large railway lines and has good load-bearing capacity and stability.
Arc-shaped rails are suitable for curved parts of railway lines, which can ensure that trains run smoothly on curved tracks and reduce friction and vibration caused by turns.
According to the material, it is divided into carbon steel rail, high-speed rail and light rail.
Carbon steel rails have good strength and toughness and are suitable for most railway lines.
High-speed rails are steel rails specially designed for high-speed railways. They have higher strength and wear resistance and can meet the operating requirements of high-speed trains.
Light rail is a relatively lightweight steel rail with lower cost and less noise, suitable for urban rail transit systems.
According to the purpose, it is divided into main line rail, branch line rail and import and export rail.
Mainline rails are rails that carry the main transportation tasks in railway lines and can withstand the weight and operational impact of large trains.
Branch line rails are the transitional part connecting the main line and the branch line, and usually carry the transportation tasks of smaller trains. Branch rails are relatively light and suitable for lines with small transportation volumes.
Import and export rails are rails that connect railways with ports, factories and other places.
