Why did the China locomotive have to be replaced by the American one when it arrived at the Qinghai-Tibet Railway?

This is because locomotives produced in China need electricity to supply them, and it is impossible to build a power supply station at such a high altitude on the Qinghai-Tibet Plateau. However, the locomotive in the United States uses an internal combustion engine to make the train move steadily and is relatively safe, so whenever it arrives in the Qinghai-Tibet region, it will be replaced with an American-made locomotive.

friends who have been to Qinghai-Tibet, we all know that the air in that place is very thin and the altitude is very high. That is to say, building a railway in the Qinghai-Tibet region, thus making it convenient to travel there, has become a matter of great concern to the state.

China did. It is precisely because of the opening of the railway there that the local economy has developed rapidly, which has also facilitated many tourists. But when we take the train to Golmud or Lhasa. Generally, trains will be replaced with American-made headsets, because before this section of the road, the altitude is relatively low and the journey is relatively smooth. Once you reach Golmud and Lhasa, the altitude will suddenly increase and the ground will become steeper and steeper.

At present, there is no way to build a power supply station to supply power to the locomotive of China, so at this time, we can only use the locomotive of the United States to drive the train. In fact, the principle of this car is the same as that of driving a motorcycle up a mountain. The old electric car doesn't have the horsepower to go up the mountain. After all, electricity can't compare with the power brought by burning fuel. Secondly, although this section of the Beijing-Qingdao Railway is steep, the journey is relatively short, so the number of trains will not be many, and passengers on the train don't have to worry about the harm caused by changing locomotives. After all, China Railway has always done a good job in safety.
