Classification and specification of rail

Rails can be classified and classified according to different standards and uses. Here are some common rail classifications and specifications:

1. Standard classification: According to national or regional standards, the rail can be divided into different types, such as Chinese standard (GB), European standard (EN), American standard (AREMA), etc.

2. Track type: The rail can be divided into ordinary track and high-speed railway track. High-speed rail tracks require higher strength and accuracy to accommodate the operation of high-speed trains.

3. Weight level: The rail can be divided into different levels according to the weight per unit length, such as P50, P60, P65, etc., indicating the weight per meter length.

4. Rail type: The cross-section shape of the rail also has different classifications, common including UIC rail type, AREMA rail type and so on.

5. Specifications and dimensions: the length, width and height of the rail will be specified according to the specific needs and standards, such as the length is generally 12 meters or 25 meters, the width and height are different according to the rail type and standards.

6. Special purpose tracks: In addition to conventional railway tracks, there are some special purpose rails, such as electrified railway tracks, tram tracks, etc., which may differ in some sizes and designs.

The specific classification and specifications of rail vary by region, standard and application. In specific railway projects, appropriate rail classification and specifications are selected according to the needs to ensure the safety and operation efficiency of the railway.
