Now the fastest high-speed train in China is Fuxing, with a top speed of 400 kilometers per hour and a standard speed of 350 kilometers per hour. However, in July of 20 1 1 year, the speed of high-speed rail in China slowed down on a large scale, from the previous 350 km/h to 300 km/h.
However, since 2065438+September 2007, the running speed of Fuxing high-speed train in Beijing-Shanghai high-speed railway has been restored to 350 kilometers per hour, while the running speed of other high-speed railway lines is still the original standard for the time being. As far as the development of high-speed rail is concerned, it has been in a state of progress, and I believe that the speed can be effectively improved.
However, passengers will always have a starting point and an end point in the process of taking the high-speed train, so the speed of the high-speed train will still have a limit, and it is impossible to maintain the highest speed all the time. And in the process of high-speed rail operation, with the increase of speed, the resistance caused by air will also increase, thus affecting the speed of high-speed rail. Therefore, the speed of high-speed rail is a process of slowly accelerating first, then increasing to the highest speed, and then slowly slowing down.
