Why is the train speed in our country still very slow? Why can't we speed up?

The train in China is slow, and the Fuxing high-speed train has run 350 kilometers. The high-speed rail is generally about 300 kilometers, and the speed of the train is 250 per hour.

Main trunk lines of ordinary trains (such as Beijing-Guangzhou and Longhai). ) all run at a speed above 100km. Because of the design, road conditions, car body and other reasons, the speed of some lines is relatively low, but it is also above 60 km. Compared with 10 years ago, the overall situation has been greatly improved, and the price of ordinary trains has not increased in 15 years. Although there is still a lot to be improved in Tiezong, it has done a good job.

As for some trains you mentioned, they are still relatively slow. This is determined by many factors. The most critical line, each line has a design speed that will lead to safety accidents, followed by stops. The more stops, the longer the natural time, and the slower the speed.
