Super Weapon Swap System

"On the ordinary track, this kind of high-speed train can start, but if you want to give full play to its advantages, you still need a special track." at this time, the train has been on the road. Qin Guan felt the comfort of the train on his newly decorated special train and communicated with other personnel at the same time.

Now, the feet keep making a clang sound. This sound will be made whenever the wheels pass through the gap between the rails. On the train, the clang sound will accompany you all the way.

This is determined by many problems. The first is the manufacture of steel rail. Each section of steel rail is 25 meters long. After transportation, the steel rail will be laid on the base. Then, the steel rail and the steel rail are connected through components, so that there will be a gap between the two steel rails.

Of course, this gap also plays a role, which is thermal expansion and cold contraction. When the external temperature changes, this gap between rails can release the tension problem caused by this effect.

Ordinary trains may not have much impact, but when the train speed is high, this gap will have an impact, not just the problem of comfort. When the wheel passes through this gap, the impact is too large, which will seriously affect the service life of the wheel, and even in serious cases, there will be the risk of derailment.

This is a problem encountered on the level road. When turning, the curvature of track design should also change with the change of train running speed. The faster the speed, the greater the curvature. Therefore, after the high-speed train starts in the future, there must be a special railway.

"Yes, Mr. Qin, you can think of all these. It's amazing. Now, we are only responsible for the research and development of trains, tracks and construction, and we also need the research and development of comrades from relevant departments."

To make the high-speed railway a reality, seamless rail is a difficult problem that must be passed. It requires welding the 25 meter long rail. Only field welding is a big problem. It also needs to ensure the welding quality and overcome the problem of thermal expansion and cold contraction of the rail. Therefore, although this problem seems small, it is not easy to solve.

"Yes, we should keep up with the supporting equipment. When these problems are solved, we should also start building the first high-speed railway. This first railway will be cross era. We should build such a high-speed railway from the southernmost coastal city to the north to the capital, connecting the north and south of our country, greatly facilitating our passenger transportation."

The first high-speed rail line must be such a major artery running through the north and south. With such a railway, the north-south traffic speed can be greatly improved. Although there are civil airliners, if compared, the high-speed rail has its unique advantages.

In China, the development momentum of high-speed rail is the strongest. Why can't other countries develop? An important problem is land acquisition. In many western countries, land is privatized. If people don't sell it, the high-speed railway must be avoided. In this case, the laying of high-speed railway is impossible. Therefore, the West would rather vigorously develop civil aviation than high-speed railway. In the west, there are many airports, almost every city has airports, and routes are crisscross.

However, aircraft take-off and landing will have noise and be affected by bad weather. Too many dense air lines will also bring great problems to the air force. Therefore, civil aviation is the main city, and ordinary cities are finally interconnected through high-speed rail, which is the best solution.

The laying of high-speed rail will also drive the economic development of many places. After passing the high-speed rail, the one hour living circle will be greatly expanded, which will greatly promote the economic development. Only when the economy of Han country is greatly developed and the comprehensive national strength of Han country is enhanced, can it be a truly powerful country. If only the army is developed, To develop the military power into a strong one, that is, militarism. If the Xiong state takes this road, it will usher in a drastic change, and the date palm state 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 change of scenery outside the window and feeling the continuous development of the motherland.

As the train goes westward, it becomes more and more desolate. The land of the motherland is vast. However, the regional development is also quite unbalanced. Today's metropolises are located along the east coast. Poverty and backwardness can still be seen everywhere in the inland areas of the West. The land here is barren, the income from planting crops is very small, and there are almost no factories here, Can not have a large number of local employment opportunities, so one of the main ways for people here is to go out to work.

This is also inevitable. Population concentration in big cities is a trend. In any country, the main population is concentrated in big cities. Several metropolitan areas almost include 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 stops at the terminal of the existing railway. Moving forward, it is the newly erected railway. This railway will pass through its own plateau and connect with the railway of the holy country!

"President Qin!" just after getting off the bus, Qin Guan immediately met a familiar old friend, Wu Lei.

At this time, Wu Lei was wearing an army coat. The temperature was always very low on the plateau. His face was full of excitement: "President Qin, I didn't expect to see you here!"

Wu Lei is an old friend of Qin Guan. When the North heavy truck factory was just beginning to develop, Wu Lei encountered some problems in buying vehicles. Qin Guan even went to the coal province to save him. After that incident, the relationship between the two sides became better. Later, under the guidance of Qin Guan, Wu Lei's transportation career has become bigger and bigger. Up to now, Wu Lei also participated in the construction of the railway.

"Are you outsourcing?" Qin Guan asked Wu Lei. Wu Lei untied the button of his military coat and revealed the uniform of the transportation company, which was not from the railway department.

"Yes, the construction here needs a lot of private forces to enter. There are a lot of outsourcing projects. I won some business through bidding," Wu Lei said.

He is very low-key now. In fact, Wu Lei took his own transportation company to undertake the earth rock transportation business of the whole section. He has also been running back and forth in the whole construction site for some time. When he came back here this time, he happened to meet Qin Guan. Naturally, he was very happy.
