Why do Chinese trains have to be made in the United States as soon as they arrive on the Qinghai Tib

In recent years, China's tourism industry has developed rapidly, especially in holidays, many scenic spots have become a sea of people, very lively. There are also many tourists in remote areas such as Xinjiang and Tibet, but people who have been to Xinjiang and Tibet know that every time they arrive at the Qinghai Tibet railway, they will change the front of the car to the United States. Why?

You know, the altitude of Qinghai Tibet is very high, which is very different from that of other regions. Ordinary people almost have plateau reaction when they go there. In fact, not only we ordinary people, but also slight changes will take place when the train arrives here. Especially at the Golmud stage, the railway will become steeper and steeper.

Our Chinese made cars are powered by electricity, but at such a high altitude, it often seems difficult. American locomotives are propelled by internal combustion engines, so they are more suitable for these high-altitude railways. Therefore, under the comparison of various aspects, they usually choose to replace them with American locomotives, which is also for the sake of safer travel.

This principle is also easy to explain. Both Chinese made trains and American made locomotives have their own advantages. But we should learn to use local materials and use appropriate resources in a reasonable place. Only in this way can we make our travel safer.

We have to say that from this point, we can also see the importance of cultural integration. There are so many countries in the world, and each country has its own advantages. We should learn to learn from each other's strengths to make up for our weaknesses. Only in this way can we make continuous progress.
