commonly used rail models
1.Standard Models
The commonly used standard models in my country are (kg/m): 38, 43, 50, 60, 75, U71Mn, etc. Among them, 38, 43, and 50 are ordinary rails, suitable for ordinary railways, while 60, 75, and U71Mn are suitable for high-speed railways and heavy-duty railways. These rails have the characteristics of uniform specifications, stable quality, and long service life, and are the mainstream rail types used in railways.
2. American models
The commonly used rail models in the United States are ASCE25, ASCE30, ASCE40, ASCE60, ASCE75, etc. These rails generally adopt a structure with a wide bottom and steep sides, with high surface quality requirements, long service life, and strong bearing capacity, and are suitable for heavy-duty railways.
3. Foreign standard models
In addition to American models, there are also standard models from different countries such as German, Japanese, and Russian. Among them, the structures of German and Japanese rails are similar, both of which are flat bottoms, short side guards, and inclined flanks. The Russian rails have a unique standard, with a horseshoe-shaped upper section and a large side curvature, which is suitable for cold climates.
4. Special models
In addition to the commonly used standard models, there are also some special rail models, such as T-rails, Y-rails, C-rails, etc. These rails are mainly used in special scenarios, such as railways inside mines or narrow mountain railways, and have their own special uses.
In general, the choice of rail models should be considered according to the specific railway conditions and usage scenarios. Different rail models have different characteristics and advantages and disadvantages. Choosing the right rail model can improve the safety and efficiency of the railway, reduce the frequency of maintenance and replacement, and reduce operating costs.
