50KG heavy rails are mainly used in the following scenarios:
National railway trunk lines: It is a common track type for trunk railways in the national railway network. For example, important railway trunk lines such as the Beijing-Harbin Line, the Beijing-Shanghai Line, and the Beijing-Guangzhou Line, which undertake a large number of passenger and freight transportation tasks, can withstand the impact of frequent train loads and high-speed operation, ensuring the safety and stable operation of the railway.
Large-scale factory and mine enterprise railways: In some large-scale factories and mines, such as steel mills, coal mines, and mines, a large amount of raw materials and products need to be transported. Railways laid with 50KG heavy rails can meet the operation needs of large freight trains in factories and mines, withstand the pressure of heavy-loaded goods, and ensure the efficiency and safety of railway transportation.
Some lines in urban rail transit: The rail transit systems of some cities, such as subways and light rails, may also use 50KG heavy rails on some specific lines or sections. For example, when the subway line needs to cross complex geological conditions or is expected to have a large passenger flow, 50KG heavy rails will be selected to provide better carrying capacity and stability.
