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

Why is the Qinghai-Tibet Railway unidirectional? 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, in some places where high-speed rail cannot reach, such as the Qinghai-Tibet Railway in Tibet, it still relies on trains to complete transportation tasks. The railway was built with the efforts and clever construction of engineers. ?

There are 85 stations from Xining to Lhasa. 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. However, friends of the 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. Qinghai-Tibet Railway is a single-track railway. What should we do if there is an oncoming train? The answer is unexpected.

First of all, let's understand why the Qinghai-Tibet Railway is a single-track railway. In fact, I think there are two main reasons. First of all, the 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. Workers and technicians are prone to high altitude reactions, which will affect the construction efficiency of the whole project, and the cost of monorail is already 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 track cannot meet the transportation demand, the state can consider investing in the construction of double tracks.
