In order to encourage Bo Jue's spirit of invention, Zhu Youxiao specially approved the allocation of 100,000 taels of silver to set up a construction machinery factory, which was specially used to produce construction machinery. In fact, this money is no longer very attractive to Bo Jue, but it is only Zhu Youxiao's recognition of his invention spirit, which is the real reason why he is happy.

Bo Jue is dedicating himself to the design of various machinery, and the technical workers have turned Bo Jue's designs into real objects. Then carry out a test one by one, in line with the design requirements, on mass production, do not meet or do not fit the needs, let the technical workers continue to transform, whether it is Bo Jue or the level of technical workers continue to make progress in production, design and manufacture of more and more construction machinery, gradually there is a batch of supply, began to enter the practical field of construction workers, these construction machinery must also allow these construction workers to be proficient in use, The factory's skilled workers had to teach them how to use and make simple repairs.

At the same time that Bo Jue's construction machinery factory manufactures construction machinery, Lei Zhensheng and Lei Zhenzhou brothers are taking technicians from Beijing to Tianjin to measure on the road, and the brothers are very serious about the work, carefully measuring and calculating the amount of work little by little, and the actual measurement of the length of the road in a mile and a mile is encountered.

The terrain of this era is still relatively primitive, there are no ready-made roads to use, there are no roads in many places, especially to many river sections, railway bridges must be built, which requires a large amount of cement, so under the guidance of Zhu Youxiao, the cement production of Daming has been able to meet the needs of building bridges, which does not need to worry about anything, the only thing to worry about is whether the standard of cement can reach the required hardness, which requires the Lei brothers to experiment.

The station in Kyoto is the starting point, in order to take care of the hearts of the ministers and the people, Zhu Youxiao asked the Lei brothers to set up the station in Beijing outside Chaoyangmen, this is because Zhu Youxiao does not want to tear down a section of the city wall because of the construction of the railway, so as not to be entangled in the imperial history, and even affect the Lei brothers, anyway, it is not too far, Zhu Youxiao is also lazy to do much, and this is also an experimental railway, and there is no need to make a big deal now. The construction of the station is very simple, just a few rows of houses, and then the starting point is drawn from here, and the foundation stone is laid, and the railway takes a relatively direct line, and there are some hills between Beijing and Tianjin, in addition to the dense large and small rivers, except for these places, which take the shortest straight line possible.

The collection of stones for the construction of the railway did not dare to be mined from the mountains near the capital, and they were also afraid that the officials would say that the dragon veins were mined from the mountains west of the western suburbs, so Lei Zhensheng used hundreds of pots and camel machines of all sizes to transport stones day and night and lay the foundation of the roadbed. The cement factory was built in Qamdo, where it was also the address of the Beijing cement factory in later generations, where a large amount of cement was fired, and the sleepers of the railway were generally made of wood, Zhu Youxiao in order to minimize the cutting down of the forest, he took the cement sleepers of the later generations, made the sleeper prefabricated parts directly near the cement factory, and then pulled to the paved gravel roadbed. The rails of the railway are light rails, which are converted into the standard of 8 kilograms per meter, the standard length is 12.5 meters, and the width between the rails is 800 centimeters. This is the weight, length, and width specially stipulated by Zhu Youxiao, as for the truth, Zhu Youxiao can't say it, anyway, the small railway in later generations is basically this standard, maybe this is better construction or more in line with the standard, these Zhu Youxiao don't know, but the emperor said so, the people below have to do this, and there is no reason to talk about it.

After Lei Zhensheng and Lei Zhenzhou's painstaking measurements and calculations, the railway from Beijing to Tianjin is a total of 280 miles, and the total length of the rails is 560 miles, plus the cement sleepers also need steel bars, so calculated, the total weight of the steel required reaches 6,000 tons, which is not a big deal for Tangshan Iron and Steel Plant, but because the steel required for the production of rails belongs to special steel, this requires Song Yingxing to carry out some transformation of Tangshan Iron and Steel Plant, which is not a big deal. Under Zhu Youxiao's silver offensive, the entire railway began to be built rapidly.

Because of the large use of various engineering vehicles, the construction speed of the railway is much faster than that of the small local railways of later generations, although the power of the camel machine is much smaller than that of the diesel-powered engineering vehicles of later generations, but it is much more efficient to carry the shoulder shoulder of the manual. It took less than four months from the beginning of the design to the completion of the entire project, which is also very fast compared to later generations. Since the rails, sleepers, cement, and construction machinery were all provided by the Daming Royal Trading Company, the total construction cost of this railway did not exceed 400,000 taels of silver.

After the railway was completed, all that remained was to transport the steam locomotives and carriages to the railway for trial operation. In fact, the laying of this railway is from both ends at the same time, from Tangshan made rails, carriages are transported by railway, little by little from the beginning of the use of sections, in the process of laying has been operated, now the trial operation is just the test of the whole process of opening need to be fully accepted, once the acceptance is successful, the first and the world's first railway in the Ming Dynasty began to be officially used, opening a precedent for railway transportation, which is also a new starting point for the industrial revolution powered by steam engines.

On the sixth day of December in the seventh year of the Apocalypse, the weather was clear, cloudless, the soft sun shone on the land outside the capital, and it was a relatively warm day in the cold winter. At the railway station outside Chaoyangmen, crowded with people to see the excitement, Ming Emperor Zhu Youxiao with his queen Zhang Yan, the second concubine and four children came to the train station, this is a very happy day for Zhu Youxiao, today is a good day for the acceptance of the Beijing-Tianjin Railway, Zhu Youxiao in order not to hinder everyone's happy atmosphere, did not wear the emperor's clothes, but wore plain clothes and his family together, Luo Sigong and Jinyiwei naturally also hid around them, secretly guarded, Zhu Youxiao did not want to disturb them, It's just very low-key to watch with his wife and children.

Song Yingxing, who is responsible for today's acceptance work, is the secretary of the Ministry of Industry, whether this is a government or private, it is a new thing in the Ming Dynasty, and it is also a huge project, not only to transport goods in the future, but also to transport passengers, so its safety must be guaranteed. Song Yingxing took the members of the Ministry of Engineering and Xu Guangqi, Sun Yuanhua, Bi Maokang, Zhu Ling, Bo Jue, Fang Yizhi and a group of bigwigs of the Ming Academy of Sciences into the first carriage, Lei Zhensheng, who was responsible for the construction of the railway, and Song Yingxing's disciples entered the locomotive and were responsible for the operation of the locomotive.

The locomotive was filled with coal and water, and the steam engine began to ignite, slowly filled with steam, and then began to deflate, with a dull low sound, the train began to run slowly, and as the pressure of the steam increased, the speed of the train began to increase. Today's trial operation is not only to test the safety of locomotive operation, but also to test the power of this steam engine to see how high the maximum speed of the vehicle can be, but now it can only test the safety, and dare to test the speed on the way back.

When the train reaches a speed of forty miles per hour, Song Yingxing asks for a period of smooth operation, and tries to let the locomotive and the railway carry out a certain run-in, don't look at the speed of forty miles per hour is not fast, it is a great speed in this era, this is about the same speed as ordinary horses, you must know that the usual speed of the pot camel machine is only thirty miles per hour, and if it is too fast, it will fail. After the train ran smoothly at this speed for an hour, there were no problems with the condition, indicating that this speed can still guarantee safety.

At this time, Song Yingxing proposed to speed up, after Lei Zhensheng received the order, he asked Lei Zhenzhou, who was responsible for driving, to increase the use of coal, the speed of the train increased with the power of the steam engine, began to gradually accelerate, and slowly the pointer on the speedometer reached a speed of sixty miles per hour, at this time on the train, people felt the difference in speed, the sign pole on the side of the road flashed back quickly, most people's heartbeat began to speed up, and some people even felt obviously uncomfortable.
