The difference between high speed rail bullet trains, why can t trains speed up

1. Strictly speaking, the EMU is a train type, and the high-speed rail is a type of railway line. The two are not the same concept. However, in China, bullet trains and high-speed railways refer to different types of railway lines.

EMU refers to the type of train. It is a unique name in China, which is different from the previous ordinary trains. Under normal circumstances, ordinary trains are pulled by locomotives, and the carriages themselves are not powered; The EMU car itself has power, and when it runs, not only the locomotive drives, but also the car "runs on its own", so that the power can be dispersed and the running speed will be faster.

At the same time, compared with ordinary trains, the vibration and noise of EMUs are on the low side. Therefore, the bullet train is a train type that is different from ordinary trains.

2. The Ministry of Railways currently defines that EMU refers to a railway line with a speed of 200 kilometers per hour; High-speed rail refers to the speed of 300 kilometers per hour of the railway line, generally speaking, the bullet train in the ballasted railway, the high-speed rail in the ballastless railway (ballast, is the meaning of rocks, coal and other fragments, the ballastless track refers to the track without small stones), in the current China, the bullet train and high-speed rail refer to two types of railway operation, the speed of the bullet train is at the level of 200 kilometers per hour, and the speed of the high-speed rail is at the level of 300 kilometers per hour. At present, there are more than 1,000 bullet trains, more than 500 high-speed rail trains, and more than 100 intercity high-speed rail trains.

3.If the train can speed up to more than 200 kilometers, the country will not spend 100 million yuan to build a kilometer of high-speed rail.

The difference between high-speed rail and bullet trains in China is speed.

If it is more than 200 kilometers and less than 300 kilometers, it is a bullet train.

More than 300 kilometers is called high-speed rail.

The main reason why the speed of the train does not increase is not the cost at all, but the impact of high-speed rail on civil aviation, if the speed of high-speed rail is 380 kilometers, or even exceed 400 kilometers.

Then no one will continue to make planes within 1500 km.

Airbus, Boeing interests do not allow.

Interest groups in domestic large aircraft are not allowed.

Therefore, the people can only continue to pay for the interest groups.

In addition to factional reasons, the reason why Liu Ministries is finished, more importantly, he offended Airbus Boeing and the German-French-Japanese high-speed rail interest groups.

So it was taken down by the American imperialists **.

When it comes to high-speed rail, I believe that many small partners will compare our country's high-speed rail with the high-speed rail of other countries, after all, the technology of China's high-speed rail has advanced by leaps and bounds in recent years, and it has reached the world's leading level in many aspects. But in fact, many people don't know that the origin of high-speed rail is not China, but Japan across the Pacific Ocean, but after decades of development, our China's high-speed rail technology has been similar to Japan, and in terms of total mileage of high-speed rail, we have even surpassed Japan to become the world's first. Friends who often take high-speed rail know that under normal circumstances, the speed of high-speed rail is 200-300km h, and China's fastest Fuxing high-speed rail is about 350km h.

Isn't 350km h too conservative? Let's take a look.

We all know that before the advent of high-speed rail, China's railway transportation mainly relies on trains, the speed of trains generally does not exceed 120 kilometers per hour, this speed is about the same as the speed of cars, in today's increasing demand for travel is actually not enough, and then we gradually developed high-speed rail, although the speed of high-speed rail is generally very fast, but there is an old saying that "there is no fastest, only faster" The faster the speed of high-speed rail, the higher the time and efficiency of people's travel, So countries around the world are also trying their best to increase the speed of high-speed rail, at present, our fastest high-speed rail in China is Fuxing, with a speed of 350 kilometers per hour, so how about this speed, can it be improved?

In fact, we can compare the high-speed rail in Japan with the high-speed rail in foreign countries to understand that the speed of Japan's high-speed rail is similar to that of China, and the maximum speed of most trains will not exceed 300 kilometers per hour, so we still have an advantage in terms of speed in China's high-speed rail. At present, the world's fastest high-speed railway, which has been put into use, is our China's Fuxing. In this regard, the expert said:

Our China's Fuxing can reach a top speed of about 400 kilometers per hour, and we are still developing a faster and safer high-speed railway, which is expected to reach a speed of 600 kilometers per hour, which can shorten the time by nearly 30% once it is opened, which can greatly improve people's travel efficiency. As for whether the current speed of 350 km h is conservative, in fact, I think this speed is already the top level in the world, and there are very few trains in the world that can exceed the speed of 350 km h, so it should be more appropriate to use the word "avant-garde" to describe it.

Finally, the principal concluded: China's high-speed rail is currently the fastest is the Fuxing, as for whether it can be faster this can only be left to time to prove, but we in China are still testing more new models, and the speed will be faster. Finally, the president believes that compared with other countries, China attaches more importance to the development and demand of high-speed rail, after all, China has a large area, a large population, and busy transportation, and I believe that there will be more advanced trains in the future, so let's look forward to it.

I think China's high-speed rail can be speeded up again, the current speed of high-speed rail is already quite fast, people's living standards have been improved, greatly reducing travel time, if the speed is increased again, it can be more convenient for people to travel.

It can definitely be accelerated, because the times have been progressing, and the speed of high-speed rail has been improving accordingly.

In my opinion, China's high-speed rail to 350 kilometers is already the most limit, because no matter how high this number is, it has no practical significance, and the speed of 350 kilometers is the best.

Personally, I think that with the current situation, it is impossible to speed up again, because I think the current high-speed rail has reached the fastest speed.

Can China's high-speed rail speed up again, and is the current speed conservative? Hear what the experts have to say.

You can't speed it up. Speed up! There will be uneasiness. How fast is the high-speed rail running now

Why can't high-speed rail increase at will? What factors are involved?

Its hello, 1, safety factor. Once the speed of the high-speed rail increases, the thrust of the two wheels of the train will increase, and the spacing between the two rails will be adjusted; Once you don't grasp the track distance, the car will be destroyed and people will die, and the high-speed rail gauge is relatively fixed and cannot be easily adjusted. 2. Locomotive life.

Long-term high-speed driving has a certain impact on the life of the locomotive, and the air resistance coefficient is an important factor affecting the life of the locomotive. Studies have shown that when a high-speed train runs 300 kilometers, the air resistance coefficient is about 80%; If you run 350 km, the drag coefficient increases by about 40%. 3. Economic reasons.

The speed of high-speed rail will become faster, and the electricity consumption will increase correspondingly, and the economic cost will increase. In the management of high-speed rail, the labor intensity and testing degree of workers should also be considered. After 0:00 a.m., it is the time for workers to inspect and deal with hidden dangers on the high-speed rail, and the speed will increase the labor intensity of many workers, including the detection intensity.

All say that high-speed rail cannot be arbitrarily accelerated.

Compared with high-speed rail, high-speed trains are faster.

The speed of the bullet train is generally about 200 250 kilometers per hour, that is, the fastest speed will not exceed 250 kilometers per hour. However, the speed of high-speed rail is much faster than the speed of bullet trains, and the average speed per hour will reach more than 300 kilometers.

The difference between bullet train and high-speed rail:

1. The speed of high-speed rail is not the same, the speed of high-speed rail is much faster than the speed of bullet trains, and the speed of ordinary high-speed rail must reach more than 300 kilometers per hour. However, the speed of the bullet train is basically about 200 kilometers to 250 kilometers per hour, so if you are in a hurry and want to get there quickly, you can take the high-speed rail.

2. The rails are different, the bullet train can basically run on the ballasted railway, and the high-speed rail needs to run on the ballastless railway, so the high-speed rail is a more stable means of transportation than the bullet train. The EMU is a weakly powered decentralized system, and it is no problem to run on an ordinary track, but the high-speed rail is a strong dispersion system, so it must be on a special track to run.

3. The configuration of the car is also different, and the internal facilities of the EMU are relatively simple, basically only first-class seats and second-class seats. The facilities inside the high-speed rail are relatively rich, and there are various different levels of seats inside, such as business seats, first-class seats, second-class seats, etc., and the space is generally relatively spacious, so the comprehensive grade of the bullet train is lower than that of the high-speed rail.

Hello, friend.

High-speed rail and bullet trains are two different things.

"High-speed rail" is the abbreviation of "high-speed railway", and "EMU" is a "passenger rolling stock with scattered power" running on railways (ordinary railways (less than 200km h), rapid railways (200-250km h) and high-speed railways (more than 300km h)).

At present, some of China's newly built railways are high-speed railways (200-250 km h) and some high-speed railways (300-350 km h), so the trains used are ordinary EMUs (200-250 km h) and high-speed EMUs (300-350 km h). In addition, it is pointed out that in fact, the international standard for high-speed railways is 200kmh, so China's newly built high-speed railways; Rapid Rail; It can be called a "high-speed railway" along with the existing railways that have been accelerated to 200 km h. However, in order to distinguish the boundaries of various railways, the Ministry of Railways did not call railways higher than 300 km h high-speed railways in various planning plans, but changed the term "fast railways".

No, high-speed rail is faster than bullet trains.

Compared with high-speed rail, bullet trains and high-speed trains are faster, mainly because of the difference in design speed. The EMU is designed to be designed according to the speed of 200 kilometers per hour, with a maximum speed of 250 kilometers per hour, and the high-speed rail is defined as a speed of 300 kilometers per hour and a maximum speed of 350 kilometers per hour when it is designed. Therefore, high-speed rail is faster than bullet trains.

Although the starting point and end point of the high-speed rail and the bullet train are the same, but the distance traveled in the middle and the train station is not the same, generally speaking, the distance of the high-speed rail is much longer than the bullet train, and the train station passing through the middle is much more than the bullet train station, and each stop for the high-speed rail needs to consume a lot of energy, so although the starting and ending points of the bullet train and the high-speed rail are the same, their ** still has a big difference.

High-speed rail will be faster. Under normal circumstances, the speed of high-speed rail is more than 300 kilometers per hour in Fanchong, and the speed of bullet trains is more than 200 kilometers per hour, so the speed of high-speed rail will be relatively faster.

Whether you are taking the high-speed train or the bullet train, you need to arrive at the station 1 hour in advance, and reserve enough time for security checks, ticket checks and queuing to enter the station.

Generally, high-speed trains start with the letter "G", and the full name is "high-speed EMU bureau passenger train", and the EMU generally starts with the letter "D", and the full name is "EMU passenger train Lali".

During the high-speed rail train, remember not to make loud noises, so as not to affect the surrounding passengers.
