The feeling of ordinary people is very wonderful, there is a process of change in the adaptation to speed, from the initial fear, to the later excitement, or to the last stop when the fear, this is a normal adaptation process, most people have this feeling. At a speed of sixty miles per hour, the train traveled for another hour, and gradually people began to adapt to this speed, seeing everyone from tightly grasping the handrail, to slowly talking and laughing later, Song Yingxing's face gradually became cheerful, Xu Guangqi, who had been sitting next to him, never squinted, I don't know what he was thinking, Bo Jue and Fang Yizhi, the two young people, have always refused to sit down, running around in the carriage, and the atmosphere in the whole carriage is very flat. Song Yingxing asked Lei Zhensheng to reduce the speed of the train to a position of fifty miles per hour, and maintained this speed to reach Tianjin, and the first half of the whole test was very smooth, and there were no accidents on the way.

In the process of returning, the train needs to be tested at the limit speed, in order to prevent accidents, Song Yingxing let these bigwigs of the Ming Academy get off, this is Zhu Youxiao's special order, that is, Song Yingxing must also get off, only Lei Zhenzhou and Song Yingxing's disciples remained on the car, Lei Zhensheng was also asked to get off, which made everyone speechless, is it afraid of death? Song Yingxing explained to everyone that he was not afraid of death, the purpose was to prevent accidents, now the people in the car are enough to test the data, there is no need for everyone to take risks, this is arranged by Zhu Youxiao.

Lei Zhenzhou has enough confidence in the railway and the locomotive, and after leaving the Tianjin Railway Station for half an hour, he commanded the workers to speed up, and slowly the speedometer increased from sixty miles to eighty miles, at this time the train began to tremble slightly, and the noise in the car began to increase, except for these reactions, there was no other reaction. Running steadily for half an hour, seeing that the locomotive was not abnormal, Lei Zhenzhou ordered to continue to accelerate, the speedometer was constantly changing, the shaking amplitude of the locomotive increased somewhat, and even began to have some bumps, Lei Zhenzhou's face was calm, and he gave various orders steadily, so that the testers could come down again. When the speedometer showed that it was 100 miles per hour, the locomotive was obviously in a hurry and it was not easy to control, especially the steam engine had reached the limit, and the time only lasted for a short time, Lei Zhenzhou ordered to reduce the amount of coal, so that the speed of the car slowly decreased, and returned to the speed of 60 miles again, and the locomotive began to be very stable.

After passing the limit speed test, and then carrying out several brake tests, and finally finding the most economical speed, Lei Zhenzhou left the command platform, and he didn't have to worry about the rest of the matter, let the real train driver start driving, and it was to take turns to drive, so that the managers responsible for locomotive operation in the future gradually adapt to the process of managing the train. After two hours of continuous testing, everyone gradually adapted to the operation of this huge train, and finally the train arrived at Beijing Railway Station smoothly, and the acceptance process ended smoothly.

The railway from Beijing to Tianjin was finally opened, and the locomotive drove nine carriages to run smoothly on the railway, each carriage could carry 45 people, or the corresponding weight of goods, and the economic running speed was maintained at about 50 miles per hour. In this era, this is a remarkable speed, all of a sudden the speed of people walking three or four miles has increased tenfold, so that people from Beijing to Tianjin back and forth time from ten days to less than a day, greatly convenient people's travel and the transportation of goods, various benefits have been significantly improved.

At the meeting of the Ming Cabinet, Zhu Youxiao personally presided over the meeting, and the main body of the meeting was to discuss the issue of railway construction. The railway from Beijing to Tianjin cost a total of 420,000 taels of silver, but its benefits are very obvious, whether it is passenger or freight, its transportation capacity is more convenient and economical than the original transportation, the average cost of 1,500 taels of silver per mile, it will not take ten years to completely recover the cost, this is the result that can be obtained after a simple calculation. Zhu Youxiao now sold the railway directly to the Ministry of Industry, and the price is only the cost price, which is completely dedication, of course, the Ming Dynasty is also Zhu Youxiao's, which is equivalent to the cost of paying from the inside. Zhu Youxiao gave a general explanation to the cabinet members about the cost and future benefits of building the railway, so that everyone could have a clear idea of what he was doing, lest he say that he was taking advantage of the household department in vain.

The benefits of building a railway are obvious, this topic has naturally been unanimously agreed by everyone, and then Zhu Youxiao proposed to everyone to build a large number of railway plans, but also to build all double-track railways, Zhu Youxiao introduced the benefits of double-track railways, it is basically not affected by the intersection of locomotives, can continue to send multiple trains, although the cost is twice as high as a single line, but the efficiency is several times higher, don't look at the current travel by train is not much, after the formation of habits, The volume of transportation will increase exponentially.

Another more important thing is that with the continuous expansion of the Ming Dynasty, the constraints of transportation are getting bigger and bigger, that is, even information transmission is a serious problem, but railway transportation can solve this problem very well. There are more than 4,000 miles from the southernmost tip of the territory to Beijing, and if it takes 800 miles to send a letter in an expedited manner, it will take about six or seven days, and this must be non-stop, and only a few people can reach it.

If the railway is built, the situation will be greatly changed, the average speed of the locomotive is 60 miles per hour, a day and a night can travel more than 1,000 miles, and the messenger can get a full rest on the car, the time is almost halved, the most important thing is the speed of transporting troops in the future, in addition to the whole team time, after getting on the train, you can quickly reach the destination in four or five days, and the soldiers will not be too tired at all, which is the greatest military advantage.

Zhu Youxiao's suggestion is that first of all, the railway from Beijing to Tianjin should be built into a double line, and the next step is to continue to extend to Tangshan and Qinhuangdao, and in the future, the railway will be built to the northeast, and the entire northeast will be networked with railways, so that the resources there will be continuously transported into the customs. There are two railways to be built from Beijing to the south, that is, the Beijing-Guangzhou line and the Beijing-Shanghai line in later generations, and then the Longhai line will be built, which is to better consolidate the Western Regions, this railway will be built for a long time, but it must be built well, Zhu Youxiao plans to build all the railways in sections, and operate a section after repairing a section to minimize costs. Zhu Youxiao's suggestions were unanimously agreed by the cabinet members, and the next step was to let the Ministry of Industry be responsible for the implementation of the plan, and things became very simple.

It is expected that the priority construction is the Beijing-Guangzhou railway, after the construction of the Beijing-Guangzhou railway, all kinds of materials will be easier to transport, all the railways must use the rails of Tangshan Iron and Steel Plant, this is because Song Yingxing has transformed Tangshan Iron and Steel Plant, only here can produce qualified rails, Anhui Iron and Steel Plant and Handan Iron and Steel Plant have not had time to transform, is expected to be transformed next year, after all, it still takes a lot of energy, but because the railway from Tangshan to Tianjin will be built soon, At that time, it can also meet the needs of the railway, as for the Longhai line, the rails needed there can be transported through the Beijing-Guangzhou line and the Beijing-Shanghai line.

The stone is made of local materials, and now this kind of stone is available everywhere after all, there is no need to limit it to one place, and the transportation cost is a huge amount, which is completely unnecessary. The production of cement also needs to expand production as soon as possible, which is not a big problem, it is much simpler than steel production, in later generations of small cement enterprises everywhere, the process is relatively simple, as long as the quality of raw materials is strictly controlled, according to the specified process of production, there are not too many problems.

The railway has to pass through quite a lot of rivers, in the current period, the amount of water in each river is much larger than that of later generations, in order to solve the problem of railway bridges, Zhu Youxiao proposed to Lei Zhensheng, Lei Zhenzhou brothers on-site pouring technology, this is an advanced technology of later generations, its advantage is firm, much stronger than prefabricated parts, since the railway engineering is a permanent project, then its first requirement is to have firm characteristics, but the shortcomings are also obvious, the construction difficulties have increased a lot, A portion of the cost is added to this. However, in Zhu Youxiao's thoughts, as long as it is for the quality of the problem, it is necessary to spend a certain price, he has seen such construction in later generations, that is, the roof is poured on site, which is much more beneficial than the roof built with prefabricated panels, and now it is used to teach the Lei brothers, and it may become the Lei brothers' unique skills.
