Why the Qinghai Tibet Railway does not use electric locomotives

Electrification is a very important project, and it is difficult to repair and maintain power plants, which is why electric locomotives are not used!

The main thing is that the power is still a little bit worse.

You tell me? Electrification is another important project, and the construction of power plants will cause even more damage.

From the point of view of historical development, everything is a development process from primary to advanced: railways, like the steam-internal combustion - electrical, have to go through the development process of wooden sleepers, stone sleepers, single-line and double-line, electrical, high-speed, and magnetic levitation.

From the point of view of technical conditions, the investment in the laying of electric railways is very large, not to mention the Qinghai-Tibet Plateau with high altitude and lack of oxygen in the altitude. China's current electric double-track railway accounts for only 1 5 of the country's railways, so it is reasonable for the Qinghai-Tibet Railway to adopt a single-track internal combustion ordinary railway as a symbol of the development of the railway into Tibet.

Qinghai-Tibet RailwayLocomotives are now not domestic, using the United StatesLocomotive

Although the construction of the Qinghai-Tibet Railway is great, and the domestic locomotive can also reach the world-class level, the final use of American locomotives is forced by the environment of the Northwest Plateau.

The weather in Tibetan areas is very bad, the temperature difference between day and night is very large, although our country was able to build an excellent locomotive, but it is also excellent on the plains, and it is not so perfect when encountering severe cold and high-pressure weather, and the lack of power alone leads to too slow climbing, if there is strong wind and rain.

The NJ2 front of the United States perfectly solves these two points, the NJ2 front of the car on the plateau is extremely good, not only can be unimpeded in the altitude of 2828 meters, unharmed, the power will not be reduced by half a point, the most amazing thing is that the front of the car has according to the altitude.

The function of automatic adjustment is really a locomotive tailored for the Qinghai-Tibet Railway.

Problems encountered in the construction of the Qinghai-Tibet Railway.

The Qinghai-Tibet Railway is located on a high-altitude plateau, and there are too many problems to encounter. First of all, the Chinese team arrived on the Qinghai-Tibet Plateau.

At first, they were stunned by the beautiful scenery of the snow-capped mountains in front of them, and only after a while did they realize that these snow-capped mountains were the roads they had to open, and all the frozen soil in front of them was also one of their biggest problems.

After a long period of minus Celsius, the frozen soil formed by the combination of ice and soil is called permafrost, and many people think that most of the permafrost is pure and contains some prehistoric viruses, but that only refers to the Antarctic glacier, the permafrost of the Qinghaimu Tibetan Plateau has a thawing - freezing cycle, so it is full of great variables in the project.

Secondly, the Qinghai-Tibet Plateau is not only full of various wild beasts, but also national protected animals.

When it appears, it can neither break into the territory of those wild beasts, nor destroy the homes of national protected animals, so what is a detour? Or is it a detour? How to shorten the distance to the extreme became the main task of the construction team in China at that time.

In response to these two situations, China has innovated by replacing the original foundation with a stone ventilation subgrade and replacing the railway with a bridge, which not only solves the problem of frozen soil, but also does not interfere with the habitat of animals.
