Liang Haiping picked up the newspaper again and looked at it, and said: "Xiaoyuan plans to introduce a tram? But it looks quite like a subway, and it would be good if it could be changed to a subway and a dual-purpose electric rail in the future." ”

Liang Yuan smiled and said: "Uncle guessed wrong this time, the Federal Republic of Germany didn't want to build this line into a tram at all. ”

"Uncle, pay attention, there is no pantograph common on trams above these trains. Liang Yuan said as he pointed to the five-section streamlined train formation.

Liang Haiping picked up the newspaper again and looked at it, and sure enough, he felt that these trains were different from the common trams or railway systems, although the pictures in the newspaper were not of high resolution, but Liang Yuanping still noticed that the viaduct where the train marshalling was actually T-shaped, and after carefully looking at the pictures of the train marshalling in operation, Liang Haiping suddenly felt that these trains were actually running on T-shaped tracks, what kind of train was this? Liang Haiping had a big question in his heart.

"Sure enough, it's different from ordinary trains, Xiaoyuan doesn't say that I haven't paid attention to it, these few trains are actually running on tracks, I really haven't seen it, Xiaoyuan, what kind of train is this thing introduced in the newspaper?" Liang Haiping asked.

Liang Yuan handed the newspaper to Liu Wenyue, who was also puzzled, and then said: "Uncle, this thing is called a maglev train, and it is a new means of transportation in the Federal Republic of Germany. ”

"Magnetic levitation?" Liang Haiping repeated with some confusion.

Although Liang Haiping has made great efforts in railway transportation in the past two years, he is finally a monk halfway through the way, and he does not know much about some more cutting-edge or obscure technologies.

"This car sounds mysterious. In fact, the principle is very simple, magnets have a strong attraction to steel-like substances, Uncle must know. ”

looked at Liang Haiping and nodded. Liang Yuan continued: "The maglev train in the Federal Republic of Germany takes advantage of this characteristic of magnets, and now a steel plate is installed at the bottom of the "T" shaped rail. ”

"Then the lower part of the two sides of the vehicle is wrapped around the inside of the track. On the top surface of the inversion part of the lower part of the vehicle, a magnet with a strong magnetic force is installed to form the appearance that the steel plate is on the top and the electromagnet is on the bottom, and there is an electric current flowing through the electromagnet after the vehicle is started, and the magnetic force generated by the electromagnet attracts the steel plate installed at the bottom of the T-shaped rail, and the vehicle is lifted upward. Liang Yuan pointed to the chic T-shaped track in the newspaper.

"When the force of attraction is balanced with the vehicle's gravity, the vehicle can levitate at a certain height above the rails. Pass guò to change the current. You can change the magnitude of the magnetic field strength to adjust the height of the levitation. ”

Liu Wenyue listened to Liang Yuan's words, looked at the newspaper and sighed: "It turns out that this is maglev, just after the New Year, the newspapers on the island introduced this new type of transportation, but the reports at that time were not accompanied by pictures, just a simple introduction to the advantages of this kind of train." ”

At the end of the eighties. In the early 90s, the Taiwan authorities of the Kuomintang of the Kuomintang (KMT), which had started a great economic exhibition on the island, decided to build a high-speed transportation artery connecting Kaohsiung and Taipei's two major economic centers, the north and south.

"Oh. Lao Liu, the authorities on the island are also interested in maglev trains?" asked Liang Yuan with some curiosity.

"Well, there is news that the government of the Republic of China intends to build a new high-traffic artery, and the maglev train should be one of the alternatives. Liu Wenyue said.

Liang Yuan, the famous name of Taiwan's high-speed rail in later generations, still knows that this high-speed transportation trunk line project that only started construction in 1998. In the end, under the strong intervention of Lee Teng Hui, who has the title of Japanese remnant, he chose Japan's Shinkansen technology. The introduction of the Shinkansen 7oo series high-speed train is a case study of the export of Japanese Shinkansen technology overseas.

However, at this time, President Chiang Ching-kuo, who was known as the pioneer of democracy in Taiwan, had just passed away, and the notorious President Lee Teng-hui had not yet shown a disgusting face that I was of Japanese descent, and the government of the Republic of China at this time was more inclined to introduce high-traffic arterial technology in Europe in Germany and France.

If the technology source of Taiwan's high-speed railway could have been determined a few years earlier, Taiwan's high-speed rail market would not have fallen into the hands of the Japanese, Liang Yuan thought with some sigh.

How could Liang Yuan know that Taiwan's high-speed rail has been delayed for a long time, purely because the Kuomintang authorities attached a political condition to the purchase of maglev trains or high-wheeled gauge trains, and the Kuomintang authorities at that time proposed that if they purchased German maglev train technology, the additional condition was that Germany agreed to sell submarines to Taiwan, and if they purchased French technology, the additional condition was that France agreed to sell military aircraft to Taiwan.

Considering the influence of China's Big 6, the German and French governments rejected Taiwan's conditions, and as a result, after Lee Teng-hui led the rise of the Taiwan independence forces, he casually threw this piece of fat into the mouths of the Japanese.

"Xiaoyuan, how fast is this kind of train?" Liang Haiping noticed the words Liu Wenyue said about the high trunk line.

"Uncle, I still remember what I told you at Tokyo University last year that the future train will be as high as 5oo-6oo kilometers. Liang Yuan said with a smile.

"Hey, it's so fast?" Liang Haiping took a breath of cold air.

"Hehe, this one in front of me is not so fast. Liang Yuan said.

In the later declassified documents of the Federal Republic of Germany and the GDR, the two sides mentioned the maglev project, which ran through the whole of Berlin.

At that time, the Federal Republic of Germany did not come up with the TR-O6 type formation, which had just set a record of 4O6 kilometers and manned maglev trains in 86, but took out the TR-O5 maglev formation, which had been exhibited at the international transportation exhibition in Hamburg in the late seventies.

The TR-O5 maglev train is the world's first maglev passenger transport system put into practical use, and it caused a great sensation at the international transportation exhibition in Hamburg that year. During the three-week expo, the TR-O5 maglev train carried a total of more than 50,000 passengers according to the transportation plan, while Japan, another maglev train technology powerhouse, did not complete the maglev train carrying five people until 1987 on the M1UOO1 type maglev train.

"Uncle. The one I and yours is a maglev train that uses conduction technology, while the maglev train developed by the Federal Republic of Germany uses normal conduction technology to propel levitation. The pole is between 4oo and 5oo kilometers per hour. ”

"4oo kilometers per hour is fast enough, so fast to catch up with the plane, it is too wasteful to use it in the city of Berlin. Liang Haiping smacked his mouth and said.

"Berlin has 4oo kilometers of poles, trains reach 4oo kilometers, and the noise alone is almost catching up with jet planes taking off and landing. ”

"The Federal Republic of Germany proposes to build a new transportation system throughout Berlin this time, and the maglev technology it intends to use is based on the TR-O5 maglev train, which completes the world's maglev passenger transport tasks. ”

Liang Yuan flipped through the newspaper in front of him, pointed to a series of numbers and said: "The TR-O5 modified maglev train is 28 meters long. With a weight of 31.8 tonnes and a maximum of 96 seats in a 2+2 manner, the train suspension system uses electromagnetic support and the guided propulsion system adopts synchronous long stator linear motors, with a design height of 137 km/h, and is expected to traverse the entire Berlin city in 25 minutes. ”

"Sounds good, but it's a new transportation system. Even if we can introduce technology, how to produce it in China, how to operate it, where to use it, and most importantly, which department leader does this thing belong to?" Liang Haiping asked a series of questions.

Liang Yuan secretly admired Liang Haiping after listening to what he said, it is no accident that the uncle was able to mix into a successful person with a net worth of tens of millions in his previous life. In a blink of an eye, I saw the biggest problem encountered in China after the introduction of magnetic levitation, who is the leader?

After six years of hard work, the wheel-rail faction overturned the maglev faction to the ground. Although the defeated maglev faction collapsed and sank into the Beijing-Shanghai high-speed railway, it also left behind a backhand that may be able to turn over in the distant future.

Driven by the maglev faction. Wusong Pudong, the economic center of the Republic, not only built the world's maglev line that was officially put into commercial operation, but also left the big tail of the Shanghai-Nanjing line maglev.

Putting aside the technical issues of right and wrong for the time being, an important factor in the defeat of the maglev faction is that the entire maglev industry chain is outside the control of the Ministry of Railways of the Republic.

The Prime Minister of the Republic of China and the Mayor of Wusong City, who promoted the maglev technology on the Beijing-Shanghai high-speed railway, both intended to build a new large-scale industrial cluster with maglev technology as the core in the Yangtze River Delta region, so as to improve the core competitiveness of the Republic.

However, things in the world are often unsatisfactory, and the powerful Prime Minister of the Republic is no exception, and the Ministry of Railways, which has been passive, naturally fought back desperately.

Professor Yao Mengshu, then an academician of the Chinese Academy of Engineering, a professor at Northern Jiaotong University, the director of the Tunnel Center of China Railway Engineering Corporation, the director of the Institute of Tunnel and Underground Engineering of the School of Civil Engineering of Northern Jiaotong University, the deputy chief engineer of the Tunnel Engineering Bureau of the Ministry of Railways, a deputy to the Ninth and Tenth National People's Congress, and a member of the National Committee of the Chinese People's Political Consultative Conference, once spoke out the core differences between the two factions on behalf of the wheel-rail faction of the Republic.

Although the Republic obtained the track construction technology of the maglev train through negotiations, the core technology such as the body of the maglev train is still in Germany, and the imported products cannot introduce the technology.

With a history of nearly 100 years, the wheel-rail railway technology of the Republic has formed an industrial army specializing in locomotive design, scientific research and innovation, and has an industrial chain of more than 400,000 people with decades of design, manufacturing, operation and maintenance.

Finally, Academician Yao emphasized that magnetic levitation technology is in the hands of a few experts and professors, and it does not have the application conditions.

Putting aside the technical veil on the surface of the matter, the root of this is a battle for the leadership of the future republic's railway, if maglev becomes the main technology that dominates the future high-traffic arteries of the republic, it means that the power structure within the Ministry of Railways will be earth-shaking changes, at least countless technicians who rely on wheel-rail technology to eat will definitely have a bleak future in the future, and countless people who have worked the wheel-rail cause all their lives will be eliminated by the tide of the times in a blink of an eye.

Liang Haiping's question is definitely asking the most essential core of the matter.
