Chapter 2414: High-speed rail development

"On ordinary tracks, this kind of high-speed train can be operated. However, if you want to take advantage of its advantages, you still need a special track." At this time, the train was already on the road, and Qin Guan was newly renovating it. On the special train, feel the comfort of the train, and at the same time communicate with other personnel.
Now, the humming sound is constantly being made under my feet, and this sound will be made whenever the wheels pass between the gaps in the rails. On the train, the humming sound will be accompanied all the way.
This is determined by many issues. The first is the manufacture of steel rails. Each section of the rail is 25 meters in length. After being transported, the rail will be laid on the foundation. Then, the rail and the rail are connected by components. , So there will be a gap between the two rails.
And this kind of gap, of course, also has a certain effect, which is thermal expansion and contraction. When the outside temperature changes, the gap between the rails can release the tension problem caused by this effect.
Ordinary trains may not have much impact, but when the speed of the train is high, this gap will have an impact. It is not just a problem of comfort. When the wheels pass through this gap, the impact is too great. , It will seriously affect the life of the wheel, and even in serious cases, there will be a risk of derailment.
This is a problem encountered on flat roads. If it is a turn, the curvature of the track design will also change with the changes in the running speed of the train. The faster the speed, the greater the curvature will be. Therefore, when After the high-speed train starts, there must be a special railway.
"Yes, President Qin, you can think of all of these. It's really amazing. Now, we are only responsible for the research and development of trains, rails and construction. We also need the research and development of comrades from related departments.
For high-speed railways to become a reality, seamless rails are a difficult problem that must be passed. This requires welding a 25-meter-long rail. Just welding in the field is a big problem, and it must be welded. Quality also needs to overcome the thermal expansion and contraction of the rails. Therefore, this problem may seem small, but it is not easy to solve it.
"Yes, we have to keep up with the supporting equipment. When these problems are solved, we will also start to build the first high-speed railway. This first one will be a trans-era. We must start from the southernmost Coastal cities, all the way north to the capital, are constructed with such a high-speed railway that connects our country from north to south and greatly facilitates our passenger transportation."
The first high-speed rail line must be such a large artery running through the north and south. With such a railway, the traffic speed between the north and the south can be greatly increased. Although there are civil airliners, if you compare it, the high-speed rail is unique Of the advantages.
In Han, the development momentum of high-speed rail is the strongest. Why can't other countries develop? An important issue is land acquisition. In many western countries, land is privatized. If people do not sell it, the high-speed rail must be avoided. In this case, the laying of high-speed rail is impossible. Therefore, the West would rather vigorously develop civil aviation than High-speed rail will be developed. In the West, there are many airports. Almost every city has an airport, and air routes are crisscrossed.
However, the take-off and landing of aircraft will be noisy and will be affected by bad weather. Too many dense aviation routes will also cause great problems to the air force. Therefore, the main cities have civil aviation, while ordinary cities will eventually pass. High-speed rail interconnection is the best solution.
The laying of high-speed rail will also promote the economic development of many places. After the high-speed rail is passed, the living circle will be greatly expanded in one hour, which will greatly promote the economic development. Only the economy of Han country will develop greatly. When the country’s overall national strength increases, it will be a truly powerful country. If it only develops the army and strengthens its military power, then it will be military and military. If Xiong takes this path, it will usher in a drastic change. Zao Guo is also drifting away on this road, waiting to be cleaned up by the Western world.
Now, Qin Guan is sitting on the train, watching the changing scenery outside the window, and feeling the continuous development of the motherland.
As the train goes west, it becomes more and more desolate. The motherland’s territory is vast. However, the development of the region is also quite uneven. Nowadays, metropolises are located along the eastern coast and the western inland areas are poor. And backwardness can still be seen everywhere. The land here is barren, and the income from growing crops is very small. There are few factories here, and there are no large number of job opportunities on the spot. Therefore, one of the most important ways for people here is to go out to work.
This is also inevitable. The concentration of population in big cities is a trend. In any country, the main population is concentrated in big cities. A few metropolitan areas almost cover most of the population. If the motherland wants to develop into a super industrial power, it must be the same way.
In the evening, finally, the train stopped at the terminal of the existing railway, and further forward, it was the newly erected railway. This railway will pass through its own plateau and will be connected to the railway of the holy country. !
"President Qin!" Immediately after getting out of the car, Qin Guan met a familiar old friend, Wu Lei.
At this time, Wu Lei was wearing a military coat. On the plateau, the temperature was always very low. His face was full of excitement: "Mr Qin, I really didn't expect to see you here!"
Wu Lei is an old friend of Qin Guan. When the Northern Heavy Truck Factory was just beginning to develop, Wu Lei encountered some problems with the purchase of vehicles. Qin Guan even went to the coal province to rescue him. That incident After that, the relationship between the two parties improved. Later, under the guidance of Qin Guan, Wu Lei's transportation business became bigger and bigger. Up to now, Wu Lei has also participated in the construction of this railway.
"Are you outsourcing?" Qin Guan asked Wu Lei. Wu Lei unbuttoned his army coat, revealing the uniform of the transportation company, not from the railway department.
"Yes, the construction here requires a lot of private forces to enter. There are many outsourcing projects. I won some business through bidding." Wu Lei said.
He is talking very low-key now. In fact, Wu Lei took his own transportation company and undertook the entire construction section of the soil and rock transportation business. He also ran back and forth on the entire construction site and was busy for a while. This time he came back here. Seeing Qin Guan, he was naturally extremely happy.
