Zhan Tianyou still raised objections to the construction of three railways together. After all, this is equivalent to a triple expansion of the construction period. For a railway, this is a huge loophole. Even if the railway is built here, it will reduce the efficiency if it is three times late. The effectiveness of the railway is more reflected after complete completion.

Yang Yuanzhao accepted almost all the things about experts. The meager railway knowledge in later generations also told him that general railways are built with single lines first and multiple lines will be added in the future. This is also a general practice in railway construction. However, when measuring and designing, he insisted on measuring and designing three lines together to reduce the difficulty of repairing three lines in the future.

Zhan Tianyou didn't comment on this, especially knowing that there are almost 6,000 people in Baotou who have basically mastered the measurement and drawing personnel, distributed throughout Mongolia and Shanxi. When he measured this together, he had nothing to say. You should know that the previous Beijing-Zhangjiakou Railway was just a full 200 kilometers from Beijing to Zhangjiakou, and one by one, slowly measuring the entire project. The three lines, due to the simultaneous measurement, the workload did not increase to three times. There were so many people and the preliminary measurement results, of course, they agreed with satisfaction.

Seeing Zhan Tianyou agree with his opinion, Yang Yuanzhao put down one thing. As the designer and planner of Baotou Blueprint, he knew very well that with the help of an all-in-one machine, Baotou's production capacity will explode to the extent to which the tens of millions of tons of steel plants are not only a problem of raw materials or the things produced. It is also terrifying. Once the 16 blast furnaces are completely completed, the number of workers will keep up with the pace of the steel mill. From Baiyun Obo to Baotou, one or two railway lines will not keep up with the transportation capacity. The transport of raw materials, the transportation of finished products, and a large number of subsequent production cannot be restricted by the traffic bottleneck. The 42 kilograms of steel rails per meter are just a foundation. In the future, such roads will gradually increase.

Therefore, Baotou, which is based on light industry, connects Baiyun Obo, which is connected to heavy industry, is the case where light and heavy industry are equally important. The things produced are calculated in tens of thousands of tons or even one million tons. In addition, the core area of ​​the two-in-one future will absorb millions or even more workers. It is just this basic daily necessities, which is an astronomical figure.

Zhan Tianyou didn't understand Yang Yuanzhao's ambitions. However, he also understood that he had really met someone who really built the railway. He thought about building the railway, but he thought that it might take him several years to build the railway from Baotou to Zhangjiakou. However, after looking at the hydrology and address materials, he knew that Baotou had prepared a lot for this, plus railways and rails. Basically, his preliminary preparations could be put aside. Baotou had done everything well, and the rest was to do it according to Baotou's design. This saved at least more than a year, but with such a huge plan, not to mention the first line change, there were only a few important direct railways, which had more than a thousand kilometers. For him, it would take at least seven or eight years to complete.

Of course, Yang Yuanzhao also talked about some prospects with Zhan Tianyou. In addition to these five important trunk railways, there are also Baotou to Baiyun Ebo, and there are also Baotou as the center, including the main cities such as Baiyun Ebo, Datong, and Suiyuan as the center. This is the first ring line. The purpose of this ring line is to connect the most core cities centered on Baotou. In the future, with the expansion of Baotou's influence, it will promote the construction of the entire railway network with its financial and technological advantages, and gradually transplant some relatively strong projects to these cities to reduce the population and land pressure caused by Baotou's rapid expansion.

Next, there is the second ring line with Taiyuan as the starting point. In the ring line, there are direct railway interconnections between key cities and Baotou, thus forming a relatively dense railway belt. At the intersection of each railway, an important city will be formed. This city is not only a transportation hub, but also has other functions, such as the regional economic center or an industrial hub city.

Zhan Tianyou was completely shocked. He did not expect that Yang Yuanzhao's mentality would be so big. In his opinion, a hundred kilometers of railways would be 1,500 kilometers at just 5 railways. If the construction of 3 lines was added, it would be 4,500 kilometers. As for the two ring lines centered on Baotou, even if they were built on a single line, they would be connected by thousands of kilometers. Perhaps with the support of Baotou, a railway network could be formed here in just a few years, at least in units of tens of thousands of kilometers. Zhan Tianyou did not doubt that Baotou already had the necessary things to produce railways, rails and funds. With these two points and enough courage, if it did not encounter great force majeure, the construction would be successful.

Thinking of this, Zhan Tianyou became extremely excited. As an engineer who devoted himself to railways and studied railways for most of his life, he hoped that more and more railways behind his name would be. The Jingzhang Railway, because of its existence, has become a monument, and the railway network in Baotou will become another one.

Looking at Zhan Tianyou's excited look, Yang Yuanzhao did not doubt that once he issued an order, Zhan Tianyou would immediately start to act. He was nearly 50 years old and did not have the feeling of knowing destiny like ordinary officials. Instead, he was full of expectations and excitement about the areas he cared about. His eyes swept over a report on the table. He suddenly thought of something he seemed to have forgotten and hurriedly said: "By the way, Engineer Zhan, there is another thing you need to check about the railway to see if it can be used.

Faced with the construction plan of 5 railways and more than 1,500 kilometers, Yang Yuanzhao forgot that he asked Zhan Tianyou to check the prefabricated cement sleepers. Yang Yuanzhao knew that there must be no problem. Countless examples in later generations, even high-speed rail, used this, but Zhan Tianyou needed to confirm it for the final confirmation. After all, the construction plan of the entire railway was carried out under the control of Zhan Tianyou. It was not recognized by him, and even if there were convenient cement prefabricated sleepers, it would not be used.

"Is that so? It's related to the railway?" Zhan Tianyou was slightly curious. In his opinion, the most important thing about the railway is the rails. As long as the rails are solved and the railway is built, there will be no obstacles. What else needs his attention!

When Yang Yuanzhao brought Zhan Tianyou to the prefabricated parts factory, the huge factory area and many cement products made Zhan Tianyou amazed Baotou's processing ability. An idea flashed in his heart. Zhan Tianyou suddenly thought of a key to building a railway. In addition to the rails, the arrogant investment on the railway is a problem of sleepers and sleepers, which is also crucial to the railway.

Part of the sleepers of the Beijing-Zhangjiakou Railway are imported, and the other ones are made of local materials. Among them, they only account for one-third of the overall sleepers. During the manufacturing process, they encountered many problems. Fortunately, the construction period of the Beijing-Zhangjiakou Railway is 4 years. Four years, which is enough for him to solve many problems. Baotou's railway plan is even larger. There are 1,500 kilometers of lines and there are not many sleepers required. This needs to be done in advance. He needs to contact the Russian wood processing factory in the Far East to make this in advance, which requires a considerable investment, and even to endure the exploitation of the Russians' sudden price increase.

At this time, Zhan Tianyou was taken to such a prefabricated parts factory by Yang Yuanzhao. He looked at the high-end cement prefabricated parts, ranging from a few hundred kilograms to a few tons, and one by one, and he did not know what these were used for. To a certain extent, he had figured out the construction thing. He clearly got inspiration from the middle and felt that in the construction of the railway, he could measure and issue indicators in advance, and completed it in advance through the prefabricated parts factory. This accelerated the construction period to a certain extent, especially for some smaller railway bridges, he could submit a satisfactory answer.

In a relatively remote corner, there is a large area covering an area of ​​tens of thousands of square meters. Half is covered by a simple shed, and the other half is open-air. This is a huge area, with hundreds of workers at this time, and the tense operators there.

There is a very strange cement piece on this area. After Zhan Tianyou took a look, he found that it was different. Doesn’t this look like a sleeper? Of course, it is a bit different from a sleeper. This was made by Yang Yuanzhao based on the appearance of later generations. The two sides are high and the middle is low, leaving a relatively large area and sufficient stress-bearing surface. This is a sleeper made of cement.

"This is a sleeper, a cement sleeper!" Zhan Tianyou said with an uncertain voice. After the invention of cement, it is an important building material. Based on the research of cement and concrete, the whole world is underway. Various skyscrapers, taller and taller houses, and large dams all represent the power of human beings to transform society and nature. This power is simply vast and unparalleled. Zhan Tianyou never thought that cement could be used on sleepers.

Compared with treated wood, it is as hard as stone and has many aspects of cement parts that far exceed wood's performance, which is definitely much better than wood.

Unfortunately, for Zhan Tianyou, he was not sure about the use of any new product. The cement prefabricated parts that were not used abroad may be able to support Gundam skyscrapers, but is it really suitable for railways? What if there is a danger without going through a series of tests? (To be continued)
