Why is the Qinghai-Tibet Railway a one-way street? Aren't you afraid of the opposite train?

Why is the Qinghai-Tibet Railway one-way? How about the train opposite? After reading it, I finally understood.

China's high-speed rail and train lines are basically all over the country. Although high-speed rail has gradually replaced trains as the main transportation force, it still relies on trains to complete transportation tasks in some places where high-speed rail cannot reach, such as the Qinghai-Tibet Railway in Tibet. This railway was built with the efforts of engineers and smart construction. ?

There are 85 stations from Xining to Lhasa. It has become the only railway leading to the hinterland of Tibet. This has also greatly increased the travel frequency of tens of thousands of people in Tibet and the mainland. It also attracts many tourists to Lhasa every year. But the friends on the high Qinghai-Tibet railway know that the Qinghai-Tibet railway is one-way, that is, there is only one. This railroad track may not cause a problem. The Qinghai-Tibet Railway is a single track. What should we do if there is an oncoming train? The answer is unexpected.

First of all, let's know why the Qinghai-Tibet Railway is a single-track railway. In fact, I think there are two main reasons. First of all, construction is too difficult. As we all know, Tibet has a harsh natural environment and complicated road conditions. The cost of building a railway here will be many times higher than that in inland areas. Secondly, there will be many problems in the construction, involving some construction technologies. It will be very difficult to implement technology here, and workers and technicians will easily have high altitude reactions, which will affect the construction efficiency of the whole project, and the cost of monorail is already very high.

moreover, the transportation demand of the Qinghai-Tibet railway is not very high. The monorail from Xining to Lhasa will be able to meet the demand. However, with the gradual development of Tibet, the traffic demand in the future may continue to increase. Maybe one day, when the single line can't meet the transportation demand, the state can consider investing in the construction of double lines.
