Chapter 363 High-speed Rail

The bigger the risk you took back then, the bigger the profit you get now.

Before, they could make a lot of money every year. In 1982, they took advantage of the opportunity to buy at a low price. In addition to their political status, the influence of the Huo family expanded rapidly.

Not to mention in Hong Kong, even in Hong Kong, Macao, Taiwan, the entire Southeast Asia, and even the entire Chinese and overseas Chinese circle, Huo Yingdong is already a big shot.

He also plays a role model, actively assists in the stable development of Hong Kong, and is a pioneer in entering the mainland to develop, allowing more companies to invest and build factories in the mainland.

Moreover, Huo Yingdong actively supports the national sports cause and has taken out a sum of money to sponsor the national team to prepare for the Los Angeles Olympics in the United States.

The cooperation between Panshan Group and the Huo family has been very pleasant so far, and both sides have a win-win cooperation.

Panshan Group lacks management talents and external talents, and these Huo-style families can help.

Many assets and companies that buy at the bottom in Hong Kong will be slowly sold and diluted by Panshan Group later, and then more funds will be used to build Hong Kong and the mainland.

"The discussion on Macau is currently ongoing. Portugal is willing to return Macau in ten years for the sake of Sino-Portuguese friendship." Feng Defeng said.

Macau is related to the two cities of Zhuhai and Zhongshan.

However, compared with the complexity of Hong Kong before, Macau is relatively simpler.

Liu Tao nodded slightly, which was not beyond his expectation.

As early as half a month ago, the two sides issued a joint statement, and the general framework has been determined. Now the discussion is just some details.

The butterfly effect brought about by the flapping wings of his butterfly is still very obvious.

From the domestic point of view, China has developed faster, and the affairs of Hong Kong and Macau have been advanced by ten years.

"The work in Guangdong Province is complicated and particularly important. You must manage it well and never make mistakes!" Liu Tao said.

The entire Guangdong Province is related to the layout of Panshan Group.

For example, Yangcheng Port is still an important hub for Panshan Group's exports.

Because most of the weapons and equipment are exported through Yangcheng Port.

In order to ensure the safety of Yangcheng Port, the air defense forces here are even equipped with a set of "Aegis" air defense missile systems.

Although the possibility is not great, we have to be cautious to ensure that we are just in case.

Once those warehouses are bombed, the loss will be very terrible.

Yangcheng and Pengcheng are the two centers of Panshan Group in Guangdong Province, and then they echo Hong Kong.

Beijing.

The Spring Festival has just passed, and the sky is still snowing.

Ministry of Railways, conference room.

A meeting on the "Beijing-Kowloon Railway" project is being held.

So far, the Beijing-Kowloon Railway has completed the line design, planning work and geological drilling work.

As early as September last year, the country announced the name of the "Beijing-Kowloon Railway" project for the first time. Just after the National Day in October, it was officially announced that China will build the "Beijing-Kowloon Railway", a railway from Beijing to Kowloon, Hong Kong, and strive to be fully connected when Hong Kong returns on July 1, 1987.

And now, it is the last technical meeting before the start of construction.

After reporting on the work of the Third and Fourth Survey and Design Institutes of the Ministry of Railways, Liu Tao also gave an introduction.

He focused on the main core technologies, including track structure technology, trains, operation control systems and other key core technologies.

Many people were shocked by Liu Tao's introduction.

For example, ballastless track. You should know that the current national railway regulations are all ballasted tracks, which are laid on the basis of small stones and then sleepers or cement sleepers. However, Liu Tao proposed ballastless track, that is, the roadbed does not need gravel, and the rails and sleepers are directly laid on the concrete road, and the horizontal error of the entire line does not exceed 0.1 mm.

In terms of tracks, long-distance seamless steel rails are widely used.

The reason for using seamless steel rails is that the high-speed rail will no longer hear the clanging sound of traditional trains.

The absence of rail joints is also helpful for increasing the speed of trains.

Moreover, the turnouts all use high-speed passenger-driven turnouts, and their passing speed is much higher than that of ordinary turnouts. And the high-speed railway line has fewer curves, and the train is as straight as possible.

The track plate manufacturing technology here is something they have never heard of or seen before.

In addition, the trains used in high-speed railways are not traditional trains, but distributed power EMUs.

Distributed power trains are a type of traction method for railway trains that is opposite to centralized power. The characteristic is that the power source is distributed in the engines on each carriage of the train, rather than concentrated on the locomotive. The EMU uses overhead cables to provide electricity to drive the traction motor.

In this regard, it is very different from traditional trains. Ordinary trains are pulled by locomotives, which is a centralized power traction method.

Everyone looked at Liu Tao in shock. They didn't understand how Liu Tao came up with these technologies.

Many of the technologies here are blank in China and have never been known in China.

For example, the trains designed by Liu Tao are very beautiful, which makes the current green trains look stupid and rough. The body of the train is used to install the foundation and load-bearing frame. The body of the EMU adopts an integral load-bearing steel structure or light metal structure to meet the strength and stiffness requirements under the lightest dead weight.

There is also the bogie. Bogies are divided into power bogies and non-power bogies. Their functions are load bearing, steering, vibration reduction, and braking. Power bogies also have driving functions. Bogies are composed of frames, suspension devices, wheelset axle box devices, and basic braking devices, while power bogies also have driving devices.

There is also the traction control system, which is used to transfer energy and control operation. The traction drive system mainly refers to the electrical equipment of the train, which is divided into the transmission circuit system, auxiliary circuit system, and electronic and control circuit system. The main transmission circuit system mainly includes the main transformer, the main converter, and the traction motor. The auxiliary circuit system mainly includes ventilation and cooling devices and in-vehicle power supply devices.

Many experts and scholars who have been engaged in trains for a lifetime were stunned and confused when they heard it.

Because this is a brand new field for them.

Liu Tao did not expect that they would understand all of a sudden. It would be good enough to be able to master these technologies in ten or even twenty years.

He only needed the high-speed railway to be built according to the technology he provided. When the time came, he would know whether it was good or not after a try.

Even if the existing state-owned train manufacturing plants are not capable of producing power train sets, it doesn't matter. He will build them specially at Panshan Machinery Factory.

Liu Tao is very optimistic about whether Panshan Machinery Factory can build train sets.

With a large number of precision instruments and processing equipment, there is nothing that cannot be made.

As for whether this will affect the cake of Tie Lao Da, Liu Tao doesn't care at all. He has touched the cake of other systems more than once or twice.

With the core technology in hand, he is not afraid of Tie Lao Da at all.

Tie Lao Da is Tie Lao Da, but there are still people above Tie Lao Da who can control him, not really having the final say and covering the sky with one hand.
