Li Chengqian and the others all reacted, this is the train, but it was like they couldn't imagine how such a behemoth was cast after such a long distance, and they didn't know how this thing was going to walk.

And at the moment, they couldn't get close, so they couldn't get closer, but they still walked in that direction, and they all took the initiative to stop when they were still about a hundred meters away from the train.

Because there were people guarding in front of them, and they were also patrolling, they naturally had to obey the rules, but at this distance they were closer, so they could see it clearly, and at this time they found that the train was one by one, and there were things connected to each other.

But even so, each car is huge, especially the front one, which is even bigger than the back car.

"The wheels under them are all made of steel, but the size of this wheel is too small, can so many small wheels withstand it?" Cheng Huailiang couldn't help but ask.

"I don't know." The others shook their heads, they had no knowledge of this at all, and they didn't know that the size of the wheel had nothing to do with the mass.

"Moreover, these carriages seem to be made of iron, not to mention how much steel is needed, and how can they move with such weight? And if you look at these carriages, I counted the carriages that are currently linked, and there are as many as thirteen cars in total. Wei Shuyu next to him also added.

"I think this is probably on the front car, although I don't know how it moves, but the front car is obviously different from the others." Li Ke pointed to the locomotive at the front and said.

"We don't know today, but we should know tomorrow, and then we can ask the craftsmen." Li Tai nodded.

Everyone has no objections, but they didn't leave today, but they are all quietly watching, and the more they know about anything here for tomorrow, the more they will know when they test it tomorrow.

In fact, this is not the first time that this train has been tested, after all, this train can appear here, it must have come from the industrial city, but tomorrow's test can indeed be said to be the first test of the railway system, because tomorrow it is not only the train itself that will be tested, but also the whole system, for example, an observation station or checkpoint set up at about every three kilometers next to the railway.

Most of these checkpoints are built at road crossings, or next to bridges and holes that need to be observed, and two houses have been built at each checkpoint, the area of the houses is not large, one is only about 60 square meters, and the other is only about 20 or 30 square meters, mainly for them to serve as warehouses.

These are built for future railway employees, because in the early days of the railway, there were no traffic lights, no signal towers, and no radios, so if there was any problem, these patrolmen were needed to patrol and be responsible for safety.

This requires professional training, and tomorrow these systems will also start operating together, and the daily accommodation and meals of these inspectors have been considered by the Ministry of Railways at present, but how to operate it still takes a certain amount of time.

The main thing is the water source problem, but this should not be difficult to solve, it's a big deal to dig a well for them directly, an ordinary pressurized water well, in fact, this is not difficult, Dahan is now because of the spirit of Yumen, although the precipitation here is less than in the south, but in fact it is not too little, there must be groundwater under more than ten meters.

And with the continuous improvement of the current environment of Dahan, there will definitely be more and more groundwater at that time, so it is okay to dig wells for them, Huo Gang remembers very clearly, when he was a child, the pressurized water wells drilled in the village were basically a steel pipe that the people in the village could sometimes draw water.

Not to mention that they can now find some professional well-drilling teams, regardless of anything else, but the people next to the railway must ensure that they eat and drink.

Although Huo Gang is very clear that after the successful construction of the railway, in fact, the population may gradually migrate with the emergence of the railway, and some people may even automatically gather in the vicinity of the railway and become a small town.

These are all possible, but for now, these will not be discussed, and the distance between a station will not be too far in the future, and this time these employees between Yumen Pass and the Industrial City do not have these problems, because they are not far from the river between Yangguan and Yumen Pass, and they have time to pull water every day.

For now, these trains will definitely be timed.

However, Li Chengqian did not know this, the first day passed quickly, and it was not until the evening that Li Chengqian and the others returned to the barracks assigned to them to rest, and they were secretly discussing the train during dinner.

But they all know that tomorrow they will know how all this works, but Li Chengqian obviously thinks more, Huo Gang asked him to write a letter of thoughts to send to his father, what does that mean? Could it be that Dahan wants to export this train to Datang? Or does the Han want to build this train directly into the territory of the Tang Dynasty?

This is obviously very possible, because although Li Chengqian is now a soldier every day, he knows very well how much trade is currently between the Tang Dynasty and the Han Dynasty, and the number of carriages walking on the road every day is a behemoth, and the huge number of carriages almost fills the entire official road.

Some official roads in Dahan sometimes even have the so-called "traffic jam" phenomenon, you can hardly imagine the happiness of at least hundreds of horse-drawn carriages on the straight road, although there are not many such scenes, but many times, you can see a long convoy of horse-drawn cars walking on the road.

It's not a trading house, it's just that everyone's speed is about the same, and after walking together, they will naturally go together, especially when they go to a place where there are no people, although there are service areas every certain distance on the official road, but after all, there are dozens of miles of no man's land in the middle, and you will also encounter wild beasts.

The official road from Dahan to Datang is getting better and better, and there are people constantly repairing along the road, but in addition to the territory of Dahan, Datang is still a primitive road after all, although they have learned to flatten the road and sprinkle a layer of fine stones on it to increase the hardness and service life of the road, and the road will not become muddy when it rains.

But even so, after all, it is not a concrete road, so there will still be potholes on the road, but this is the limit of the best, and the people who built these roads are actually from some gate valve families or merchant families in different places.

The reason why they build roads is simple, they rely on these roads, and the service areas attached to the sides of the roads, to make money, or they themselves are in business.

It's just that even if these roads are built, so that the carriage of the official road from Dahan to Chang'an in the Tang Dynasty can save more than ten days of time, but for the carriage, it is impossible to reach Chang'an City from Yumen Pass without more than a month.

I just don't know how fast this railway can be.

In the early morning of the next day, Li Chengqian and the others woke up early, for Li Chengqian, today is a very important day, because today may affect the future strategic changes of the Tang Dynasty, how important this railway is Li Chengqian does not know, but Li Chengqian understands that Huo Gang is not the kind of person who has no purpose.

In fact, he really thought well, one of the reasons why Huo Gang built the railway to Chang'an and accelerated the logistics and transportation between the two places was naturally to strengthen the control of commerce over Datang, and secondly, to let Datang transport more raw materials to Dahan.

Although there is no shortage of minerals in the area that Dahan can control at present and in the future, after all, the population of Dahan is not as large as that of Datang, and the base of Datang is large, and the population is naturally more.

So if there is a train, then Dahan's goods can be sold to Datang faster, and the same raw materials can also be directly transported to Dahan, plus Datang doesn't know what trade protection is, which means that although Datang's wealth will also increase, it can't compare with the speed of Dahan's increase.

After breakfast, Li Chengqian and the others were quickly taken to the side of the train, this time no one stopped them, Li Chengqian and them followed the other more than 20 patrols, as well as many soldiers were standing together.

"Your task today is very simple, is to act as a passenger for a day, the so-called passenger is to take the train for a while, see the carriage in front of you, at present, each carriage can accommodate about 123 passengers, and this train is a total of 3 passenger cars, and 10 wagon cars, we will leave after all the goods are full, the whole process will take about two hours."

"During this process, you can watch from the sidelines, and if you find anything unusual, report it as soon as possible." As the officer said loudly that all the orders had been issued, Li Chengqian's eyes were also projected on the train.

"Disband!"

After the disbandment, everyone did not leave too far, but kept watching, and at this time they realized that the huge steel rails of the arched structure on these trains seemed to be there to lift things, but they did not know exactly how to lift this thing.

However, the shock in their hearts could not be concealed, one carriage could seat 123 people, wouldn't those three carriages be able to carry more than 300 close to 400 people? What's more, there are ten carriages behind this to pull goods.
