Isn't It Faster To Repair The High-Speed Railway? Why Do You Want To Bend It?

As our country's economic strength continues to grow, infrastructure is constantly being built, and high-speed rail is part of it. As we all know, trains can keep driving at high speeds on the more straight railways. However, the reality of the high-speed rail line is not straight, no line is straight from beginning to end. Why?

The big reason is caused by the terrain. The railway will pass through a variety of landforms, and China is divided into three major terraces from east to west. Basins, hills, mountains, plateaus, plains, and rivers and rivers are extremely complex. Building a railway in this landscape environment can be seen as difficult. Although China's mountain bridge technology is developed, some terrains are still unavoidable. 

On the other hand, the construction of the railway is mainly to facilitate people's travel, but also to promote the development of freight, and thus promote the development of the local economy. Considering the practical use of railways, the distribution of cities in China is in the topography, not all cities are on the same line. It is almost impossible to design a railway in a straight line.
