Driving the same car, why is the train speed 120 km and the high-speed rail 350 km?
First, the power of high-speed rail is greater than that of train. The standard running speed of high-speed rail is 300-350km/h, and the speed of train is 100 to-120 km/h. One of the reasons is that the power of high-speed rail is much stronger than that of train. Traditional trains only rely on locomotives to provide driving force, while each car of EMU trains will provide power, which adds up to sufficient power and of course the running speed is fast.
Second, the models and tracks of high-speed rail are different from trains. Secondly, the models and tracks of EMU trains are different from traditional trains. China's EMU trains adopt ballastless track, with large and smooth curve radius, which requires higher rail quality than traditional trains. In addition, the EMU trains adopt streamlined models, which can greatly reduce the air resistance and make the car run faster.
Third, it is safer and more comfortable to take the high-speed rail. Now the high-speed rail is very fast, and the driving is smooth, comfortable and safe, so now everyone will give priority to taking the high-speed rail when traveling. China's high-speed rail technology is very developed, which is the pride in our hearts. Foreigners will be great after taking our high-speed rail. On the high-speed rail, you won't feel trembling and dizzy at all, the temperature is comfortable and the service is better. Compared with airplanes, high-speed trains arrive on time, which is the first choice for many people to travel.
Generally speaking, the track, model, technology and power of high-speed rail are more mature than trains, so the speed of high-speed rail will be much faster. Readers, do you understand? If you don't understand, please ask questions in the comments section.
