Six hundred and ninety first chapters continue to use doctrine

On the dock, a gantry crane hoisted a carriage off the freighter.

Looking at the carriage that had just been unloaded, a strong smile appeared on Li Weidong's face.

Sure enough, as I expected, these are fully enclosed high-speed carriages! The Thais don't know what to buy, so they made me cheaper. This time it's a treasure.

The second-hand trains that Japan sent to Thailand are 183 series diesel-powered trains. This series of trains is widely used in Japan and can be regarded as the main model of Japanese diesel-powered trains.

This series of car groups has been used in Japan for decades, and it was not fully eliminated until 2016.

The performance of the 183 series is still very good, and it can be used as an express train.

The express trains in Japan can be regarded as the express trains with the prefix T in China, and the speed is second only to the EMUs with the prefix D.

Before the birth of the Shinkansen, limited express trains were also the fastest trains in Japan. At that time, the speed of Japanese express trains had already reached the highest speed of the fourth major speed increase of Chinese railways.

Although the 183 series is an outdated product from Japan decades ago, it is still a good thing for Southeast Asian countries.

As for China, if it was more than ten years ago, it would also regard the 183 series of trains as treasures. In the 21st century, it is not uncommon.

In the early 1990s, there were still many coal-fired steam trains on China's railways. At this time, the 183 series diesel-powered locomotives were still more useful for China.

Subsequently, China began to phase out steam locomotives on a large scale, replacing them with internal combustion-powered locomotives, and began to increase the speed of trains. Basically, when the train speed was raised for the third time in 2000, the Japanese Type 183 train was no longer attractive to China.

However, the fully enclosed carriages used by Japanese express trains still have a lot to learn from China.

At that time, China could not manufacture high-speed train carriages. The most advanced 25T carriage in China was authorized by Bombardier of Canada. The prototype of this carriage was the L11 high-speed train in Belgium.

As far as train technology is concerned, Bombardier is not even a first-tier echelon of high-speed trains.

In terms of high-speed rail technology in the future,

China's Fuxing is obviously the first in the world, surpassing the Japanese and European standards, followed by Japan's Shinkansen, and then the European standard, including Alstom in France, Siemens in Germany, and so on.

As for Bombardier, it sold its train business to France's Alstom for $7 billion.

In other words, the most advanced 25T carriages in China at that time could only be regarded as second-tier international products.

At that time, Japan's railway technology was the world's number one, much more advanced than Bombardier's. Not only the performance of the train set, but also the comfort and stability of the carriages, especially many detailed designs, were far superior to Bombardier's.

When it comes to digging out details, there is really no country in the world that can compare with Japan.

So when he was in Thailand, Li Weidong learned that the 183 series trains that Japan gave to Thailand were replaced by the 700 series Shinkansen. He immediately realized that these may be a batch of eliminated express trains.

At that time, Li Weidong decided to get the carriage.

The locomotives of Japanese express trains are not rare in China. In a few years, China will enter the era of high-speed rail. Who will care about Japan’s outdated diesel-powered locomotives then!

But the carriage of the express train was Li Weidong's fancy. In particular, the compartments of the fully enclosed trains have a lot of detailed designs inside, which are indeed top-notch in the world and not available in China.

...

Chen Yonghua looked at the carriages in front of him, looking at a loss.

Seeing Li Weidong approaching, Chen Yonghua immediately went up to meet him, and asked, Boss, what are you doing with these train carriages? Does Fukang Engineering still need to make train carriages?

I really want to do it, but do we have the ability! This is a train carriage, there is no thirty-year technology accumulation that can't make it. After Li Weidong finished speaking, he pointed to one of the carriages and asked; Mr. Chen , can you dismantle it?

I can't build, can't I dismantle it! Chen Yonghua paused his chest, and then said: I'm not bragging, but I can dismantle any machinery, even if I get an aircraft carrier!

Li Weidong continued: Then dismantle a compartment first, I want to figure out the layout of the ventilation system inside.

Ventilation system? Chen Yonghua was stunned for a moment, and asked subconsciously, Should we do related research and development?

Li Weidong nodded: I hope we can master the ventilation system of the carriage, but don't worry, it's enough if we can fully understand this technology in the next three years.

If it's just a ventilation system, it won't take that long. Chen Yonghua continued to ask: But if we master this technology, is there any use for it?

Li Weidong didn't answer directly, but asked instead: Mr. Chen, have you ever taken a train?

Chen Yonghua nodded, and Li Weidong continued to ask: Then have you ever met someone who eats instant noodles on the train?

I've seen people eating sandwiches in the subway. Chen Yonghua smiled slightly, and continued; But I often make instant noodles when I work overtime, and the whole laboratory smells like instant noodles, so I can imagine that in the subway What would it taste like to eat instant noodles?

Li Weidong went on to say: Even if it is to reduce the smell of instant noodles when taking the train, you must have a powerful ventilation system in the compartment!

...

There are many detailed designs in Japanese cars that other countries do not have. Among them, what Li Weidong values ​​most is the car ventilation system.

When it comes to building trains, Li Weidong really doesn't have that technology. Even if it is to manufacture carriages alone, these companies in Li Weidong's hands can't do it.

Things like trains seem like iron skins, but they are not easy to manufacture. If you want to successfully build a train, you need at least the support of a whole set of heavy industry systems. And advanced trains must have a complete industrial supply chain behind them.

Therefore, the companies in the world that can build trains are all in countries with relatively developed heavy industries. Without sufficient heavy industry support, they can only import parts from other countries to assemble a train.

None of the companies that manufacture trains in China is a product of the national system, but even so, they still need to import advanced technology and parts from foreign countries.

For example, when the Qinghai-Tibet Railway was first opened to traffic, the engines used by the trains entering Tibet at that time were produced by General Motors of the United States.

But if it's just a compartment ventilation system, it's within Li Weidong's ability.

The ventilation system of domestic carriages is terrible. In the past, green leather cars relied on opening windows for ventilation. The few vents on the roof were at most just air vents, which had almost no effect on the air circulation in the carriage.

During the Spring Festival travel season, squeezed in the carriage of the green leather train, it is really mixed. Those who eat instant noodles with the smell of stinky feet, and those who smell the smell of instant noodles pick their feet, are all daily operations. Che, the old rhinitis for many years can be cured.

Later, although the carriage was upgraded, the effect was still not much better. At least a box of instant noodles could be smelled in the whole carriage.

Even in the first few years of entering the high-speed rail era, the ventilation systems of domestic trains were not much better. In the old high-speed rail cars, the ventilation system only works when it is running. Once the train stopped, people in the carriage fainted due to lack of oxygen, it was all reported in the news.

In recent years, with the upgrading of China's high-speed rail technology, the problem of the ventilation system has been improved, and the comfort of the cabin has also improved a lot. The new domestic ventilation technology can complete the air exchange in the compartment in five minutes. Even if you eat instant noodles, the smell will basically dissipate after ten minutes.

In the era when China's high-speed rail has not yet risen, Japan's compartment ventilation system is ahead of the world.

Europeans and Americans are basically indifferent to the smell in the car. Americans have long been familiar with all kinds of shit and fart in the New York subway.

The Japanese like to pick out details, and even the hiss of urinating has to be covered up with music. With the personality of the Japanese, of course they cannot tolerate the smell in the compartment, so the Japanese compartment has been designed with a very advanced ventilation system. It was also unique in the world at the time.

The set of second-hand carriages Li Weidong bought is a closed carriage itself, and the ventilation system of the carriages has also been specially designed. It can be used directly on the high-speed rail without any problem.

...

There were lights and festoons in front of the office building, surrounded by a group of people eating melons, and the banner behind it read Ribbon Cutting Ceremony for the Establishment of Dongshan Real Estate in big characters.

Since they planned to enter the real estate industry, it was natural to set up a special company, so Li Weidong and Zhao Jinshan each spent ordinary money to establish Dongshan Real Estate.

In addition, Li Weidong also merged the team that developed the wholesale mall in Qinghe into Dongshan Real Estate.

The person in charge of this team is Ma Bin, the second son of Ma Zhongyi. He has been with Ma Zhongyi and has practiced for many years, so he has certain experience in real estate development.

Ma Zhongyi is now in a state of retirement. After all, he is old and still has three highs, so he can't work as hard as he did when he was young.

Fortunately, Ma Zhongyi's three sons are more competitive. They follow Ma Zhongyi in the business field and learn some business skills. Among them, Ma Bin is the most outstanding.

Ma Bin was not outstanding in his studies when he was a child, but he was very capable of leadership. He was the king of children in the village. After growing up, Ma Bin is also very good at interpersonal relationships. Wherever he goes, there are a group of friends who call him brothers.

It is precisely for this reason that Li Weidong asked Ma Bin to be in charge of real estate development.

At this time, Ma Bin was also at the scene, busy with the ribbon-cutting ceremony.

Seeing Li Weidong approaching, Ma Bin immediately greeted him and said, Uncle Li, the ribbon-cutting ceremony will be ready soon.

Li Weidong nodded, and said: Ma Bin, we have changed to an unfamiliar environment, we must adapt as soon as possible. And we need to have a good relationship with that person from Zhao Jinshan.

Zhao Jinshan's nephew came back from studying abroad, so he might have drank too much foreign ink. You should accommodate him a little bit, and let him stumble a few times if he really can't do it, and he will mature.

Ma Bin nodded: Don't worry, Uncle Li, I understand everything!

Li Weidong sent Ma Bin to be in charge of Dongshan Real Estate, and Zhao Jinshan naturally had to send someone, so Zhao Jinshan sent his wife's nephew.

This nephew went to the United States after graduating from high school and has just received a master's degree.

Given Zhao Jinshan's family background, his wife is naturally not a commoner, and her nephew certainly has the money to study abroad.

Ma Bin didn't even go to college. He got a high school diploma and started doing business with Ma Zhongyi. He belonged to the low-educated practical school.

And Zhao Jinshan's nephew graduated from a famous foreign university with a master's degree, but he has no specific responsibility for actual business, and belongs to the high-educated theoretical school.

It is inevitable that there will be some friction when the low-educated practical school meets the high-educated theoretical school. So Li Weidong vaccinated Ma Bin in advance.

At this time, Zhao Jinshan also came from a distance.

Brother Li, the price of coal has risen again recently. To be honest, I am a little flustered by the price increase! Zhao Jinshan said.

If you say you're losing money in business, you'd feel flustered, but now that we've made money, why are you flustered? Li Weidong asked.

I don't know, I always feel that the money is coming too fast, too simple, and a little unreliable. Zhao Jinshan said.

Energy prices have always been cyclical. The price of coal has risen sharply now, and it may fall back in a year or so. Li Weidong comforted him.

In Li Weidong's memory, this round of price cycle, the real surge started in the second half of 2007 and reached its peak in the second half of 2008. In just one year, coal prices more than tripled.

Then the subprime mortgage crisis broke out in the United States. Affected by the international situation, the coal price fell back to the price in the second half of 2007 within three months. It was a roller coaster ride.

At the same time, the country also began to import coal on a large scale in order to stabilize the price of domestic coal. So in 2009, China, the world's largest coal producer, became a net coal importer.

After that, there was another round of rising. Until 2011, the revenue of the coal industry reached a peak of 3.25 trillion yuan, accounting for 6.5% of the GDP in the same period.

Then the price of the media began to fall, until it bottomed out in 2015, and then there was a rebound cycle. It began to stabilize in 2017, and the overall income of the entire coal industry basically remained at about 3% of GDP.

It is precisely because of the cyclical factors of coal prices that coal bosses are actually not afraid of short-term losses. When coal prices are low, they grit their teeth and carry it through.

It's just that with the increase in coal imports, it will be difficult for domestic coal bosses to get rich overnight.

Li Weidong was introducing the periodicity of coal prices to Zhao Jinshan, and Ma Bin hurried over.

Mr. Zhao, Li Dong, I just received a call. The leaders who were supposed to come to our ribbon-cutting ceremony may not be able to come. Ma Bin said.

What's wrong? Could there be a problem with one of the mines? Zhao Jinshan asked subconsciously.

It's not a problem with the mine. Ma Bin continued: It is said that because of the foggy weather, the leader's car was blocked on the expressway, and it will not be able to get off the expressway for a while.

Heavy fog! Zhao Jinshan nodded, and continued: Recently, the fog has been quite heavy. I often get up early in the morning, and the visibility is only two to three hundred meters. When you look at the sky, it still feels foggy. Misty!

Li Weidong looked into the distance, then shook his head, and sighed: This is not fog, this is smog!
