Song Yingxing's scientific research team is very large, and Zhu Youxiao's silver is also taken by themselves, basically without any restrictions, which is Zhu Youxiao's greatest support for scientific research, because Zhu Youxiao understands very well that the huge cost of scientific exploration is something that no individual can afford, and must have strong financial and material support in order to continue development. Just like the "Manhattan Project" of the United States in later generations, China's national institutional development plan was all devoted to the country's efforts to complete the most basic basic research.

The funds allocated by the Ministry of Household cannot be endless, but with the huge financial resources of the Ming Royal Trading Bank and Tenglong Bank, it is still possible to assume the financial cornerstone of the rise of the Ming Dynasty, and it is not accused by any ministers, this is completely a corporate behavior, and the Ming National Treasury has nothing to do with it, which is also the most convenient place for Zhu Youxiao. But the railway can't be in private hands, even if it's Zhu Youxiao's own Ming Royal Trading Company, so Zhu Youxiao decided to build the first railway at his own expense, and if it succeeds, it will be handed over to the Ministry of Industry to operate, and if it fails, it will be his own.

After seven years of continuous research, Song Yingxing's scientific research team has reached the level of the early nineteenth century for the smelting of steel, there are thousands of smelting formulas for various steels, and there are several warehouses for the original data records of various tests.

Track steel is a special steel, even in later generations, there are many countries that can lay railways, but the rail needs to be imported, this is no way to do things, there is no certain scientific research basis, this kind of steel can not be smelted. Zhu Youxiao's periodic law table has been greatly applied in this era, and has also played a key role, many elements were gradually discovered by Song Yingxing, with the discovery of these elements, various steel smelting formulas are also endless, which gives Zhu Youxiao more choices.

Directly laying the heavy rails of the later generations is definitely not possible, the stability and wear resistance, fatigue resistance, corrosion resistance of the rail can not be reached, Zhu Youxiao can only use light rails now, this has to be experimental nature, lest the ass decide the head, lay hundreds of thousands of miles at once, and finally can not be used, Zhu Youxiao's plan is to lay the light rail train from Beijing to Tianjin first, and wait until the experiment is successful, after the improvement, and then lay a trunk railway from Beijing to Guangzhou, and then lay a trunk railway from Beijing to Guangzhou, and lay it along the Beijing-Guangzhou line in later generations. As for the other railways, it will be developed on the basis of this one.

Daming's steel mill now has a certain scale is Tangshan Iron and Steel Plant, Handan Iron and Steel Plant, Liaoning Iron and Steel Plant, Anhui Iron and Steel Plant, the steel mill in the suburbs of Beijing is Song Yingxing's test site, not a large steel plant, these are owned by the Ming Royal Trading Company, as for other small steel mills, Zhu Youxiao does not transfer smelting technology to them at all, so as not to waste resources and pollute the environment, so the current steel production is a monopoly, and small steel plants are not able to operate, and the operating costs are too high. Therefore, it cannot be developed.

The annual output of these large-scale steel mills is more than one million tons, if it is put into the future generations, it is definitely a small steelmaking that needs to be eliminated, but now they are all super-large steel plants, with a scale of 20,000 or 30,000 people, and it is absolutely impossible to use so many people in the later generations, but now they all need manual operation, and the degree of mechanization is very low. Normally, the output of these steel mills would be sufficient for daily steel consumption, and now that the railway is going to be built, it is necessary to continue to expand the steel plant.

In the Ming Dynasty, the content of iron ore is low, relatively speaking, the sulfur content is high, after Song Yingxing's scientific research team continues to test and optimize, improve the smelting technology, these problems are constantly being solved, but the expansion of production, Zhu Youxiao still put it in Liaoning, where the iron ore content is relatively high, and now it is a place with less population, will not cause too much pollution to the living environment.

The construction of the railway from Beijing to Tianjin began, but Zhu Youxiao could not find an engineer who knew how to build a railway, because there is no railway in the world now, and it cannot be said that there is no one at all. Just when Zhu Youxiao was worried about the railway construction engineer, Sun Yuanhua of the Daming Academy of Sciences recommended to Zhu Youxiao a talent who could build a railway, named Lei Zhensheng, and also introduced the origin of Lei Zhensheng, the Lei family era served the palace architecture, and has been working the palace construction since the Hongwu period, until his generation, through his family built all kinds of ancestral halls and palaces.

After listening to Sun Yuanhua's introduction, Zhu Youxiao remembered the legend of the famous "style Lei" in history, it is said that the ancestor of the Lei family, Lei Dafa, started by building a palace, starting from the long class, until he retired at the age of seventy, serving in the Qing Dynasty for more than 260 years, basically the palace built by the Qing Dynasty has the participation of the Lei family, this is a real talent, I don't know if he starts to build the railway now, whether his family will become a railway family in the future, always try to know.

Along with Lei Zhensheng was his brother Lei Zhenzhou, both of whom were in their twenties and less than thirty years old, and they looked magnificent, which made Zhu Youxiao feel comfortable from the bottom of his heart, so he took the two of them to watch the railway and steam locomotives in Huangzhuang. Zhu Youxiao means that the two of them should know what the purpose of building this railway is, and also tell them how the vehicles travel on it, what matters need to be paid attention to when building the railway, for example, there can be no right-angle turns, the turning place needs to be high on the outside and the inside of the ground, and a series of issues such as designing the arc of the railway according to the speed of the train, Zhu Youxiao himself can't explain it too clearly, because he is not from this background, and he can only explain to them the matters that need to be paid attention to.

But it seems that the two brothers are really not simple, through Zhu Youxiao's simple explanation, they understand the simple principle of this railway, as for the calculation of road repair technology, you have to look at the situation of the road when it is built, and even the two brothers asked Zhu Youxiao if he could dig up a section of this railway. Zhu Youxiao agreed to them, asked people to open a section of the railway, and told them that the rails were erected on the sleepers to make it more stable, and as for the stones underneath, it was to make the whole road evenly stressed, and there would be no derailment accidents caused by partial collapse.

After Lei Zhensheng and Lei Zhenzhou visited the railway built in Huangzhuang, they returned home and began to study how to build the railway. According to Zhu Youxiao's guidance, it is necessary to first inspect the lines for building the railway, and then calculate the amount of work required for the road and how much it will cost. Although Zhu Youxiao told them not to worry about how much money it would cost, this was just an experimental railway, and even if the construction was unsuccessful, it could be re-changed, but the two brothers thought that if the railway could not be repaired at one time, it would damage the reputation of the Lei family.

Then the Lei brothers began to set up a railway construction company and began to prepare for the basic work of building the railway. The first is to recruit people with certain computing ability, Lei Zhensheng found dozens of students who are good at computing from the Daming Academy of Sciences, as well as nearly 100 students from the Daming Institute of Technology, and these people form the most basic functional departments, and then they are waiting for Bo Jue to transform the engineering car. Bo Jue's transformation of the pot camel machine not only has excavators, bulldozers, transport vehicles, but also road rollers, hook machines, cranes, etc., as long as Zhu Youxiao thinks that for saving labor, all the lists can be pulled out instead of machinery, so that Bo Jue thinks about design. Bo Jue also recruited a large number of skilled workers to help, and he only handed over the design, manufacturing and improvement to those skilled workers, and because of this, he trained a large number of senior technicians and made great contributions to the industrial technology upgrading of the Ming Dynasty. Don't underestimate these skilled workers, without their involvement, no high-level equipment can be manufactured.
