Zhan Tianyou is a genius engineer, in the construction of railways, is an excellent engineer, but the more capable people, the more there are such and such problems, stubbornness is Zhan Tianyou's biggest problem, unless you can convince him, before the train, 2100 horsepower locomotive, the power has made Zhan Tianyou dare not imagine, this represents an average speed of more than 100 kilometers, but Yang Yuanzhao added this steam engine, it is even more amazing, increased to 3100 horsepower, weight, It is also 20 tons lighter than the previous total weight, not to mention the benefits of water pipe control and sealing, but the increase in horsepower and the reduction of weight will make the speed of the train speed up a lot, no matter what Yang Yuanzhao says, he is not willing to come down, he must personally get on the train, personally feel the excellent performance of this locomotive.

For this, Yang Yuanzhao can't either, so he had to ask the engineers to check in as much detail as possible, and let the speed of the first trip not be too fast and not be able to reach the limit, in this case, even if there will be problems, it is enough to reflect and eliminate.

Engineers, including Zhan Tianyou, are inspecting the locomotive, especially the steam engine, although this steam engine is perfectly installed on the front of the locomotive, but the outside does not look very compatible, there is a lot of space inside, a lot of it is still unable to fight people or pass the guò space, obviously, this is also a reluctant fit, these are more or less unprofessional, casting a shadow on their hearts.

The inspection of the steam engine is also the most focused, by a special steam engine engineer, carried out several levels of detailed inspection, for this Yang Yuanzhao is a little crying and laughing, this is still the problem of his system, in order to let the steam engine can enter the train, without dismantling the train for installation, he did not consider the environment of the carriage, in the future, when the next batch of locomotives come, he will directly install the steam engine, so that the effect will be better.

The one in front of me, although there is a little bit of a problem, but the performance and stability are absolutely no problem, it has been verified by the all-in-one machine, and sure enough, after several rounds of testing, the worry on the faces of engineers and Zhan Tianyou is no longer there, and it is replaced by expectation.

The train is ready, and even slowly come out of the freight yard, heading towards the railway, reaching 180 tons of locomotives, if you want to test, can not be on Zhengtai Road, the high-speed locomotive and weight, will make Zhengtai Road such a light rail railway, overturned, fortunately, this section of the station, is re-laid, not far from the station, is the heavy rail railway docking with the Baotou Railway.

The Chinese railways of this era are far less dense than those of later generations, not to mention a few minutes of trains, a day is a few passenger trains and more than a dozen freight trains, such a density, there is no need to look for a special look, just find a train just past the time, anyway, it is a little more than a kilometer, even if the train runs slowly, it will not take more than 3 minutes.

On the one hand, it is necessary to ensure that the locomotive is safe enough when leaving, 3 minutes, for a speed of about 40 kilometers per hour, that is, about 2 kilometers, there are special personnel, on the 4-storey building of the station, with telescopes for monitoring, to ensure that there are no trains within 20 kilometers, and on the other hand, the personnel are arranged on the specially demarcated 50 kilometers of test railway line.

Baotou railway, from the beginning of the design is closed, it costs a huge amount of manpower, and even a huge investment, but also separated from the barbed wire area, the railway is fully enclosed operation, for the densely populated areas with people, will also be placed in a specific location, for mutual traffic, as far as possible to do a qiē, to reduce the damage of residents to a minimum.

However, this is the beginning of the 20th century, not the beginning of the 21st century, most of the people along the way are backward areas, and the people in these villages in China have not undergone multiple education, especially the farther away from Baotou, the more so, the problem of crossing the railway is an inherent stubborn disease, even in the 21st century, it is impossible to prohibit crossing the railway, but measures such as barbed wire cannot be completely eliminated.

For this point, Yang Yuanzhao reminded Zhan Tianyou very early on that after the establishment of the Railway Bureau in Baotou, the subordinate departments have a special pathfinding team with a huge number of personnel, on the one hand, for the rescue of road construction, on the other hand, it is to patrol, patrol the rails, by the way, patrol the surroundings, find problems as soon as possible, and plug some loopholes.

At the same time, Baotou also carried out education in the villages along the railway, regardless of the cost and cost, to prevent people from crossing the railway, because this train is not traditional, only 20-30 kilometers of trains, those trains, people can go up when they run on the side, especially when they turn the corner, what is going on with the famous railway guerrillas in later generations, that's it, the speed is 30-40 kilometers per hour, when turning, it is reduced to less than 20 kilometers, and people can catch up with the speed of the train if they run quickly.

In the early days, the railways were not closed, and people could even travel freely on the railways, even if the train came, the train with a speed of tens of kilometers was enough to dodge it.

However, Baotou, from the very beginning of the design, did not plan to use low-speed trains, even if they are imported, at least the average speed of 120 kilometers per hour, high-speed, even more than 140, 150 kilometers of trains, the high-speed brought by the rapid passage and reaction time greatly reduced, directly across the railway, will face a direct threat. The noise of the steam locomotive is huge, and the movement is relatively huge, but once the reaction is not timely, or the train is coming, I am afraid that people's reaction may not be able to keep up with the speed of the train itself.

Yang Yuanzhao does not expect to completely ban train collisions, which is almost impossible to ban for thousands of kilometers of railway lines, at present, he can only do a good job of prevention as much as possible, and do a good job of publicity, however, when testing the locomotive, he does not want problems to occur.

The road guard team and the army have long been scattered, standing out from a small station, all the way to Datong, specially demarcated a 50-kilometer area, a battalion of recruits and more than 500 railway road guards, a total of 1,300 people, within a range of 50 kilometers, per kilometer, at least more than 20 people, an average of more than 50 meters, in this case, any danger is enough to avoid, under the fully enclosed road, anyone who views over the steel wire fence, will be the first time, by the soldiers to find, and prevent.

As early as when the engineers tested the locomotive and steam engine, these soldiers were sent out, riding on the road construction machinery, this vehicle based on the construction of the railway, is based on the light rail, the speed on the heavy rail is not fast, a total of 3, each can accommodate about 200 people, of course, the place where the people are located is in the rear rail warehouse, not so comfortable, fortunately, the soldiers and the road guard, do not care much about this.

The speed of about 30 kilometers per hour and the time of 2 hours are enough for these personnel to be in place, and one by one the signals came, and after Yang Yuanzhao repeatedly confirmed that it was safe, the whole test was really opened.

The red flag waved, on the high platform, the telescope made the last determination of the continuous flag, to ensure that every person was in place, had been tested, and injected enough water and coal-fired trains, began the final preparations, a large amount of coal was added to the train, under the action of the fire, burned, specially designed steam engine, can hold more coal and air, if necessary, can also add oxygen, enough to ensure that the coal is fully burned, the boiler rolls, water vapor begins to form, The steam engine began to operate slowly, the steam engine poured out countless steam, converging in the reciprocating steam engine, and the huge kinetic energy began to gradually intensify, and the preparation of the train was completed.

The whistle sounded for a long time, the sound was torn, and it spread far away, the window of the tall locomotive, Zhan Tianyou waved to Yang Yuanzhao below, and less than 9 people formed a real yàn team, 3 of them were specifically responsible for coaling the steam engine, there was also a train engineer and 2 drivers, and the remaining 2 recorders, they would judge the time of the train in passing each marker according to the timers installed in different positions on the train, the real idler, only Zhan Tianyou alone, he was responsible for the overall situation and command.

Before the train did not run, in various areas of the train, different timers were installed, they were responsible for calculating the time, this is just a rough setting, it is one of two sets of numbers, the same device and measuring instruments, arranged in various places on this railway, the current level of technology, there is no instant speed meter, but the dense time, stopwatch, and fixed distance, with another method, to measure the speed of the locomotive, can be accurate to the considerable distance, this is also this era, The basic method of train speed measurement.

As early as when it stopped, the steam engine of the train was already filled with enough energy, once the train driver let go of the train brake, when the wheels slowly rotated, the powerful steam energy, through the guò water pipe and power shaft, was converted into kinetic energy, driving the train to slowly leave the small station, after more than 100 meters, the steam engine had already accumulated enough power, countless steam rushed out, and in the shroud of water vapor, the train with a strong momentum, began to accelerate gradually, faster and faster.

On the platform, the people who watched this qiē calmly watched the train go away, and it was not until a few minutes or so later that the train completely left the small station, and then slowly relaxed, and everyone got busy according to the assigned work, while Yang Yuanzhao and Liu Shu walked into a room next to the platform, a room with a high antenna.
