Did China s high speed rail technology get from a locomotive in Japan?

Don't talk nonsense, most of China's high-speed rail technology is self-developed.

Income from legal technology transfer.

When China first introduced high-speed rail technology, it did absorb Japan's experience, but the imported technology was not a complete copy. Not to mention, the technology we absorb is not limited to Japan.

Moreover, Japan provided technical cooperation only when it wanted to get EMU orders, and it also put an end to high-tech cooperation, which has an expert's explanation on the Internet.

The Ministry of Railways' order for 140 EMUs is a condition of cooperation, requiring that the products must be manufactured by Chinese enterprises. In order to get orders, the giants (Siemens of Germany, Alstom of France, Kawasaki Heavy Industries of Japan, Bombardier of Canada) must choose to cooperate with Chinese companies and participate in the bidding through technology transfer.

In fact, the high-speed rail in foreign countries has a very short route and time. Our country is vast, the Beijing-Shanghai line alone, it takes 4 hours to run, and the Beijing-Guangzhou high-speed railway is more than 2,000 kilometers. This requires us to have higher high-speed rail technology, which has higher requirements for materials and structures, which means that our high-speed rail technology will progress faster.

So our own high-speed rail technology is definitely world-class, CCTV has a lot of documentaries about high-speed rail, it seems to be called a super project or a great high-speed rail.

High-speed railway, referred to as high-speed rail, refers to the railway tie-up system with high design standards and can be used for safe and high-speed travel of trains. The concept is not limited to tracks, nor does it refer to trains.

High-speed rail has different regulations in different countries, different times, and different scientific research and academic fields. The "Code for the Design of High-Speed Railways" issued by the State Railway Administration of China defines high-speed rail as a new passenger dedicated railway with a design speed of 250 kilometers per hour to 350 kilometers per hour and a standard gauge for EMU trains.

China's national *** defines China's high-speed rail as a new or existing line railway with a speed of 250 kilometers per hour and above, and promulgated the corresponding "Medium and Long-term Railway Network Planning" document, which includes some rail lines with a speed of 200 kilometers per hour into the scope of China's high-speed railway network.

At the same time, the "high-speed rail" is purely used by the private and China Railway Corporation's train ticket system (12306 official **) to refer to China's high-speed EMU passenger trains (G prefix trains), which is a wrong term.

On December 1, 2017, the "English Translation and Writing Specification in the Field of Public Service" was officially implemented, stipulating that the English name of the high-speed EMU standard is G-series high-speed train. On October 21, 2020, the 400km h cross-border interconnection high-speed EMU of "Advanced Rail Transit" rolled off the assembly line in CRRC Changchun Rail Passenger Car Co., Ltd.

By the end of 2020, the operating mileage of railways in China has reached 10,000 kilometers, including 10,000 kilometers of high-speed railways and 90,000 kilometers of railways in the central and western regions.

Compared with Japan's high-speed rail, China's high-speed rail can be said to be comparable, indistinguishable, and the competition for orders in the international market also has its own winners and losers. Japan's high-speed rail, which is familiar with the Shinkansen, developed relatively early, has been developed in the sixties and seventies of the last century, and it can be said that the technology is quite mature, while China's high-speed rail development is relatively late, but through the wisdom of the Chinese people's innovation, research and development, it has now caught up. Whether in terms of technology or the total mileage of high-speed rail, China's high-speed rail has been at the forefront of the world, and the current mileage of China's high-speed rail accounts for about two-thirds of the world.

If China's high-speed rail and Japan's high-speed rail are only compared in terms of technology, Japan's high-speed rail may be better and a little ahead. China's high-speed rail currently has a top speed of 350 km/h, while Japan has launched a 600 km/h high-speed train. Although Japan has developed a high-speed rail of 600 kilometers per hour, judging from the first picture announced, this kind of high-speed rail will not be put into operation until 2027, and I think that by 2027, China's high-speed rail may have been able to reach 600 kilometers per hour.

In addition, Japan's high-speed rail reaches 600 kilometers per hour in an empty state, and if it is operated at full load, it may not reach that high.

Why did you just say that in 2027, our high-speed rail may also reach 600 kilometers per hour? That's because the Fuxing high-speed railway, which is currently being tested in China, has reached a maximum speed of 480 kilometers per hour when the two cars meet. At this rate of development, it is not a dream that we will reach 600 km/h in 2027.

Another point that Japan is more advanced than China is that Japan has its own unique advantages in the high-speed rail chain, and some core components, we in China are not yet able to produce them ourselves. But China also has its own advantages, that is, the technology developed by itself is also very advanced, and the cost is cheaper than Japan. Relying on the wisdom of the Chinese, as long as new technologies appear, they can be quickly transformed into productivity, so China's high-speed rail mileage is increasing every year.

Compared with Japan's high-speed rail, there is still a little bit of a gap between China's high-speed rail, after all, people have been developing for decades, and it is a miracle that we can reach this level later. Japan's high-speed rail is better than ours in two points, Japan's high-speed rail and urban transportation are better connected, and China's high-speed rail is generally built in relatively remote locations, most of which are in the suburbs, but with the emergence of China's characteristic shared cars, Didi, etc., it can be said that this is no longer a problem. Another point is that Japan's high-speed rail bento can be said to be a major feature, many people go to Japan to do high-speed rail bento just to experience the high-speed rail bento, but our high-speed rail lunch experience is relatively poor in ** and taste.

To sum up, if it is purely compared from technology, China's high-speed rail may be slightly worse than Japan's high-speed rail, but from the perspective of China's independent innovation speed, it may surpass Japan in the next few years. Compared with Japan's high-speed rail as a whole, China's high-speed rail has disadvantages but also good aspects, which can be said to be indistinguishable.

I think China's high-speed rail is more advanced. Although China's high-speed rail started later than Japan. However, through the efforts of Chinese engineers from generation to generation, China's high-speed rail technology has become one of the best in the world, and has surpassed Japan in many technical aspects.

It must be that China's high-speed rail is more advanced, because China's high-speed rail is ahead of Japan's high-speed rail in terms of speed and construction time.

China High-Speed Rail. Because China's high-speed rail technology is world-leading and fast, it is definitely more advanced than Japan's high-speed rail.

I think it's China, our country's high-speed rail can go through caves, it's very fast, and it saves us too much time.

What is the difference between China's high-speed rail locomotive and Japan's high-speed rail locomotive? Which one is more advanced.

Our high-speed rail technology comes not only from Japan, but also from Canada, Germany and France. CRH1: The EMU produced in cooperation with Bombardier of Canada, mainly for transportation services between urban railways and intercity railways, as long-distance sleeper trains in national trunk railways, with a construction speed between 200 km h and 250 km h.

CRH2: The EMU produced in cooperation with Kawasaki Heavy Industries of Japan is mainly used to serve various new high-end railways such as national trunk railways, inter-regional trunk railways and intercity suburban railways, with construction speeds between 200 km h and 350 km h.

CRH3: The EMU produced in cooperation with Siemens, mainly used in national trunk railways and inter-regional railways, with a construction speed between 160 km h and 350 km h.

CRH5: A high-speed rail EMU in cooperation with Alstom of France, which is mainly used in the northern trunk line or interregional railway, with a construction speed of 250km h.

The high-speed rail is a complex system of engineering, consisting of a body part.

It is composed of parts, power supply parts, power supply parts, electronic control parts, bridge parts, tunnel parts, supporting facilities and other parts.

More than 20 years before the large-scale operation of China's high-speed railway, the world's high-speed rail from Germany, France and Japan has been successfully used, and their high-speed rail technology is also their own strengths, France is stronger in terms of body, Germany is more prominent in terms of electricity, and Japan has more advantages in electronic control.

You must know that the Chinese have a very deep foundation in these kung fu skills, and most of the more than a dozen bureaus built by China Railway were transferred from the original team of the former railway soldiers, who were once famous on the Korean battlefield, and at that time, under the indiscriminate bombardment of US Air Force aircraft, no matter how serious the damage to the railway was, it could be restored to traffic in a few hours.

Don't talk about Japan, the world in high latitudes, permafrost strata to build railways can not think, forced this group of people do not know much about the construction team to complete for many years, the facts have proved to run well, is its engineering and technical indicators need to be tested by Japan? No, the technical authority in this area can only be Chinese.

1. The opening time is different.

1. Japan's high-speed rail: On October 1, 1964, Japan's first Tokaido Shinkansen was opened, connecting Tokyo, Nagoya and Osaka, connecting Japan's three major metropolitan areas.

2. China's high-speed railway: In May 1998, the electrification and speed-up transformation of Guangzhou-Shenzhen Railway was completed, with a designed maximum speed of 200 kilometers per hour.

Second, the speed requirements are different.

1. Japan's high-speed rail: 270 or 300 kilometers per hour, with a maximum speed of 603 kilometers per hour (L0 maglev train, 2015).

2. China's high-speed railway: a new passenger dedicated line railway designed to run 250 km-h (including reserved) and above EMU trains, with an initial operating speed of not less than 200 km-h.

Third, the characteristics are different.

1. Japan's high-speed rail: The Shinkansen adopts a decentralized operation mode instead of being pulled by a locomotive (locomotive). The so-called power dispersion means that the wheels of each carriage are equipped with a driving device, an electric motor, to distribute the power of the train to each carriage.

2. China's high-speed rail: The high-speed rail is very smooth to ensure safety and comfort. The high-speed railways are all seamless steel rails, and the high-speed railways with a speed of more than 300 kilometers per hour use ballastless tracks, that is, the overall track bed without stones to ensure smooth traffic; The high-speed railway has fewer curves, a large curve radius, and the turnouts are mobile high-speed turnouts; Viaducts and tunnels are widely used to ensure flatness and greatly reduce distances.

1. The width of the rails is different. At present, the most widely used track gauge in the world is 1435mm, which is called the standard rail moment. More than 60% of the world's countries use the standard, mainly in Western Europe, North America, North Africa and China.

The world uses 1067mm narrow gauge railways, and the main countries are: Indonesia, India, Africa, and some countries in Central America. The vast majority of lines in Japan use 1067mm narrow gauge, with only the Shinkansen and Keihan Limited Express and Keisei Shin lines using a standard gauge of 1435mm.

2. Fares are different. Due to the high cost of high-speed rail in Japan, the fare is about twice that of China's high-speed rail.

3. Japan Shinkansen, no security check. China's high-speed railway, there is a security check.

4. Japan Shinkansen, there are non-reserved seat tickets. China's high-speed railways are all fixed seats.

5. There is a smoking area on the Shinkansen in Japan. China's high-speed rail is non-smoking.

6. Japanese Shinkansen, there is a small cart sales service. China's high-speed rail has only fixed vending counters and mobile beverage services.

7. Japanese Shinkansen, with multi-purpose rooms , private spaces for breastfeeding, changing clothes, etc. China's high-speed rail, there is no such private space to use.

8. Japan's Shinkansen, the latest and fastest high-speed rail train "Hayabusa" has a maximum speed of 300km h, and China's Fuxing CRH400 standard speed is 350km h.

China's Fuxing is the CR400 series, and the CRH380B BL BG is the Harmony.

Each has its own merits, and it is difficult to distinguish between the middle and the uncle.

Compared with Japan's high-speed rail, China's high-speed rail can be said to have its own merits and difficulties. Japan's Shinkansen has been technically mature as early as the last century, while China's high-speed rail started late, but it was independently developed and the latecomer prevailed. China has built the largest number of high-speed railways in the world, accounting for about two-thirds of the total mileage of high-speed railways in the world.

However, sharp-eyed Chinese netizens also said that there is something greasy in this: first of all, this high-speed rail does not have a driver's window, is it unmanned or is there another high-tech means to observe the road surface? This is not known.

Secondly, there is a picture showing that this high-speed rail will not be put into operation until 2027. In other words, we haven't even done trial operation now.

Finally, the fact that high-speed trains can reach speeds of 600 kilometers per hour when they are empty does not mean that they can reach this speed after full load and official operation. Secondly, is advanced really just a competition of technology?! In the past, some countries launched supersonic passenger aircraft in the field of air passenger transport, but in the end they ended up with a fiasco, and they were inferior to subsonic passenger aircraft in comfort and economy.

It can be seen that speed and technology are enough and reliable in many cases, and the same is true for high-speed railways. China has grown from scratch, from backwardness to continuous leaps and bounds, and Japan may temporarily lead China, but there are many Chinese, there is also a lot of wisdom, and the vast space is a stage for Chinese people to display their talents, and we have reason to believe that the future will definitely impress the world.
