Three railways are very necessary. The two railways are a bit nonsensical, but they occupy a small share between the whole. One branch line is only a few dozen kilometers at most. However, from Baotou to Yan'an, there is a long line. Although the straight line is only more than 400 kilometers, it is a little detour. Because the railway has to pass through the city, it takes more than 500 kilometers on the map given by Yang Yuanzhao. Such a long railway can be said to be the longest railway that Baotou may have to build. To a certain extent, it makes everyone have some concerns and many oppositions. {{}

The matter of oil cannot be said that Yan'an Oilfield is just a small oilfield. It was successfully mined the year before yesterday, and the daily oil production was only 1-1.5 tons, so there was no need to build a railway. However, from Yanqing in Yan'an to Changqing in the future, it was also an oilfield-intensive area. Perhaps it was not capable of exploitation now, but in the future, the oilfield closest to Baotou went deep into China's inland, and the geological environment was very important and it was a natural oil industry dense zone.

In the end, under Yang Yuanzhao's forced recommendation, especially the production of Baiyun Obo Steel Plant has repeatedly set new highs. In the past two months, the steel rails in Baotou have been enough to build a 1,000-kilometer railway. In the future, the production of this steel rails will continue. Anyway, it is something that is not paid, and the interests of the railway are obvious. There is no saying that the railway will lose money. This issue is still safe and finally passed.

Both Yang Yuanzhao and Zhang Zhaozhong were very happy to be able to pass so many issues at once, especially Zhang Zhaozhong. The rails placed there not only occupy the warehouse, but also rust. Building a railway will make up for the current income. However, the steel plant has never relied on income. Whether it is the current plan of 16 blast furnaces. In the future, the expansion plan of more than 50 or even 100 blast furnaces is completed with the strong support of Yang Yuanzhao. The funds are filled in, and the railway is very good. Once it is completed, there will inevitably be profits. Although it is a long-term flow in a sense, it has finally changed the situation of only leaving but not entering.

Railway is the key. The miracle Yang Yuanzhao once created, coupled with the little impact, this package of railway plans was finally established, and thus created a core area centered on Baotou and will also be the most important bases in Baotou in the future.

Baotou and a series of industrial cities such as Suiyuan, Datong, Pingshuo, Taiyuan, Yan'an, Baiyun Ebo have formed a prototype. In the future, when these trunk railways are completed, the next step is to gradually pass through the double-track lines. These cities and land are combined into a whole. With the gradual increase in the steel production of Baotou, the establishment of a large number of ring lines and railway networks, Baotou's core position has been consolidated.

Yang Yuanzhao and Zhang Zhaozhong were happy, and the other shareholders were also very happy. For the railway, no one knew that no one thought it would have more. Even the United States had completed the trunk railway on a large scale, and then some light rail branch railways were demolished. As long as three of the railways were connected, Baotou would transform from a border town into a regional hub, truly having more influence.

The shareholders finally formed a resolution. After the procedures were completed, something more formal will be formed. That is to say, this was established before Zhan Tianyou arrived, but Yang Yuanzhao did not doubt that Zhai Tianyou would agree with this. After all, the shortest of five railways is more than 100 kilometers and the longest of which can reach four or five hundred kilometers, with a total of more than 1,500 kilometers. It is longer than the railways connected to China in the past five years. The railway of more than 300 kilometers a year is just an average number for the 105 years from 1876 to 1981, and most of them were built after the founding of the People's Republic of China.

Yang Yuanzhao instructed Zhang Zhaozhong to strengthen the strength of the rail workshop and cultivate more mold masters as much as possible, so that these can promote the improvement of rail output and quality, especially quality.

Zhang Zhaozhong of course knew what Yang Yuanzhao said. It can be said that before, he did not focus on the production of railway tracks. He must pay attention to it in the future. He started the Northwest Railway plan in turn. Once the railway is built, the profit generated by the operation will be repaid first. This is very critical for steel mills.

Yang Yuanzhao sent Zhang Zhaozhong away, and he himself came to the cement factory. For almost a year, Yang Yuanzhao rarely paid attention to the cement factory. Under the leadership of Li Mingsheng, the cement factory is now different from the past. The large-scale infrastructure projects in Baotou, several highways, and the construction of the steel plant in Baiyun Obo have made the demand for cement very large. Cement is also the most important thing before Baotou, because of the changes in Baotou's residential houses, they have been connected to various places through caravans and merchants, and the sales of cement are increasing day by day. Especially in the Wuhan Quanye Association, cement is just an inconspicuous item, but it has been favored. A total of 320,000 barrels, or about 100,000 tons of exports, was finally a business worth millions of dollars.

In this era, the whole of Europe was like a powder keg, producing all kinds of arms and building various defense lines and fortresses with no chance. The demand for cement was also huge. Among the 100,000 tons, 30,000 tons were directly ordered by Germany, and some were divided up by Britain, France, the United States and others. This was one of the most prosperous eras of cement. Moreover, Baotou cement was different from Qixin. There was only one of the most common cement, high condensation, high standard, and even high hardness cement. This was the focus of cement sales. These were also recognized by the great powers. Although they did not trigger a purchase frenzy like rubber, it was also a step to go abroad.

Yang Yuanzhao did not care more about the cement factory, but everything about the cement factory is inseparable from him. In a sense, cement represents infrastructure and has the same status as steel. From the day the cement factory was built, the profits of the cement factory and the Baotou Chamber of Commerce did not pay any dividends, and basically all of them were invested in the expansion of production. Up to now, the daily production capacity has been increased from 3,000 tons last year to 35,000 tons, which has been increased by more than 10 times. A cement factory of tens of millions of tons has actually appeared silently in the entire northwest of China. Even in Suiyuan, which is close to the close, there are not many people who know about it.

This time, Li Mingsheng was found to ask Li Mingsheng to help him mobilize workers from the cement factory, and by the way, with the research institute to develop suitable sleepers. Using wood to make sleepers requires a lot of treatments, moth prevention and other treatments. It is not easy to become a qualified sleeper. The real good one is cement prefabricated parts, but this prefabricated parts must withstand a certain amount of pressure. In terms of railways, Yang Yuanzhao has no talent, but there are many math and physics. After a little calculation and finding a few data, Yang Yuanzhao can find the right stress and problems, and basically, some requirements for cement sleepers are made out.

The cement prefabricated parts factory is no longer the same as before. After almost a year of development, especially the work of prefabricated parts in thermal power, the technology of the prefabricated parts factory is improved particularly quickly. To a certain extent, as long as the stability, pressure resistance, and resistance to ordinary wind and sun exposure are reached, it can be put into use and there is no need for much adjustment.

In later generations, not to mention heavy-gauge railways, high-speed railways, high-speed railways, and high-speed railways, which are more than 60 kilograms per meter, they are not all cement prefabricated parts of various labels. In this regard, Baotou Cement Factory has reached the forefront of the whole world. The labeling and strength of cement are at least in the research room, which has surpassed this era.

High-grade cement, special steel, and research on reinforced concrete, more than 1,000 different formulas were quickly completed. These formulas did not wait for them to complete, but were only obtained from the all-in-one machine. Through the analysis of the all-in-one machine, the three most suitable formulas of reinforced concrete were finally obtained. One was the large prefabricated formula of heavy bridges. This can only be waited for later. After all, before the large and super-heavy crane was successfully developed, such cement prefabricated parts could only be used barely, and both sides spent a lot of money to make tower cranes and then transported by ship. This is somewhat unbearable for the rapid development of Baotou, especially for bridges with more than 10 tons, which are almost impossible to transport through existing conditions, at most about 10 tons. They must also be transported by modified tractors, otherwise the pressure on the road surface or land will be too high.

So this formula is just an alternative formula, and the other two formulas are used in this prefabricated parts factory. Those two formulas are the formulas of ordinary bridges and sleeper prefabricated parts. In terms of performance indicators, the standards of sleepers have exceeded the standards. They can carry ordinary trains and locomotives of this era, and can also carry super heavy trains.

Super heavy locomotives have always been the research direction of the world's railways. It is not that a train can carry just as many cars as possible. This requires power speed, or even the carrying capacity of the entire vehicle. Hundreds of cars can easily reach thousands of tons of transportation, which will even exceed an ordinary ship. But is this meaningful? The horsepower of a locomotive is limited, and it must reach a certain speed to have practical solutions. Otherwise, it would be better to change it to something else.

Everything is ready, only the east wind is needed. I ordered the prefabricated parts factory to strictly implement it according to the standards. The production department must have at least 100,000 prefabricated parts. This is not a problem for the expanded prefabricated parts factory. It will take about 3 days. By the way, it will take more than ten days to wait until the prefabricated parts are completed. In the meantime, there is only waiting for Zhan Tianyou to arrive (to be continued, please search for Astronomy, novels are better, updated and faster!
