The carriage of this train, and the train carriage of later generations, is already very similar, this similarity, of course, is not similar to the bullet train, there is no need, and it is impossible to reach that level, the similarity is the kind of green car.

The structure of the whole carriage is wooden, not that Zhao Xin does not make anything else, if you pay a certain price, there is no problem with aluminum alloy, which is also the material of the mainstream carriage in later generations.

Although it is said that in this era, the Ding Navy has been born, but it can only be produced in the laboratory and in small batches, and it is rarely used even by the army, and it is mostly accumulated and researched.

The body is purely made of steel, and the safety performance must be guaranteed, but in terms of weight, it can't stand it, a huge body, all made of steel, I'm afraid that there are not dozens, or even hundreds of tons, such a weight will increase the burden on the horse.

Some wood with better texture, their material may not be as good as metal materials such as steel, but the speed of trains in this era is not fast, at most 25 to 30 kilometers, even if there is an accident, it will not have much impact, but it has reduced a lot of weight.

In history, at the beginning of the car, almost the entire body was wooden, which was also the mainstream at that time, and Zhao Xin just copied this process.

However, part of the neat body is still made of plates, and only some key structures are made of steel and painted green, which is particularly heavy.

The body is not sealed, although the sealing of the wood is not very strong, but it is a little stuffy, with wide glass windows, people can sit there, easily see the scenery outside the window, this is also a huge innovation, the people in the car, can clearly see the outside action.

There are 4 carriages, a total of 40 horses, they are neatly sheathed in front, there are special harnesses to hold them in place, these horses are basically trained, basically, will obey the groom's command, plus special harness, enough to ensure safety.

The leather whip sounded, and at the front of the car, there were a total of 10 grooms, controlling 40 horses, they cooperated, relatively skillful, and soon, the horses began to move from stationary.

The train began to stand still, and the power of the horses gradually transmitted to the wheels, and it took almost a little time from stationary to moving, and some officials began to wonder, with so many people and such a heavy carriage, could these horses do it?

However, it is clear that this kind of doubt does not exist, because the carriage is moving, and the speed is getting faster and faster.

These officials may not understand the principles of physics, but the basic judgment is still there, the train keeps moving forward, and the scenery outside the window is constantly moving backwards, backward speed, basically, similar to the forward, maybe not comparable to the speed of fast horses, but faster than ordinary carriages.

From stationary to accelerating, it took a total of about 600 breaths, that is, 10 minutes, which is also a matter of no way, the horse-drawn train, it is almost inevitable to be subject to, the constraints of physical principles, in the initial time, from stationary to high-speed, it must go through a series of processes, only after the speed is stable, the power consumption is small.

The advantage of the railway, on the one hand, is the use of wheels, wheels than other things, on the road, to save effort, this is the basic principle, and between the railway and the iron wheel, all are the same material, friction is also quite smooth, which is equivalent to reducing the resistance to the minimum, in this sense, the same weight of this horse, the use of force, than in the ordinary road surface, is smaller.

The speed of the train keeps increasing, and when it almost increases to about 20 kilometers per hour, the increase slows down, and the train ride is relatively stable, which is almost high-speed, and it may increase to 25 to 30 in the future, which will take time.

In the carriage, all the officials were sitting, and any official had the experience of traveling for a long time, and the long journey became almost commonplace.

There is no way, whether it is to enter Beijing to catch the exam, or to take office, the official position used by the Northern Song Dynasty, among a county, the county order is a liuguan.

Exile officials also mean that they do not take office in their hometowns, and even some do not bring their family members.

Hundreds of miles, thousands of miles, long journeys are already commonplace, if you move every three years, by the age of forty or fifty, you may have moved many times.

In the middle of this, the faster they are promoted, the higher the officials, the more often they move, and it is already common for them to go far away, ranging from a few hundred to thousands, and a few have more than a dozen experiences.

Ye Qingchen's. Before becoming the third envoy, he also served as a local official, and he traveled to many places

Ox carts and carriages, and even horses and donkeys, he has experienced it, but this time, it is a little strange, how to say it, it is stable, it is too stable, and it almost does not feel the bumps, maybe in a small part of the time, there will be a feeling of fast and slow, but after acceleration, after a smooth, there is no more, it has always been very stable, and the stability is a little surprising.

If he didn't look at the scenery outside the window, he even thought that this one was not moving.

This is the advantage of the train that it is smooth, because the speed is not very high, there is no sound of rail collision, and even the noise is a little smaller.

The early trains were also like this, at most 20-30 kilometers per hour, even if there was wind resistance, and where the dog would go, basically, nothing would be lost.

This process lasted for about an hour, and the scenery was smooth and somewhat terrifying, and the scenery of rapid retreat was in the countryside, and there was no particularly familiar place, and they couldn't tell where they had come.

Just silently calculated, or acquaintances, discuss a few words with each other, where is it?

Zhao Xin knew it in his heart, and Ye Qingchen was about the same, because he had learned about the experimental speed of the train before, which could almost reach more than 100 miles per hour, but without a watch, he didn't know how much time had passed.

The watch, in fact, has appeared, but Zhao Xin hesitated, whether to push or not, the watch is the principle of the clock, it was called astronomy in ancient times, astronomy This thing has a different meaning in ancient times, Si Tianjian is responsible for the emperor, and he will judge the auspicious according to the celestial image, and there will definitely be problems with rash intervention.

But watches are only used in the Ding Navy, and even the outflow is restricted, just like Zhao Xin, in the Ding Navy, you can carry it with you, but out of the Ding Navy, you can not carry it, so you don't carry it.

However, in the era when there was no watch timekeeping, there will be some people with special talents, for example, they have some unique methods of judging time, which may not be all accurate, but can also be roughly estimated.

Alright, half an hour! An official who is proficient in this way said affirmatively.

"Where can I get in half an hour?" A young official of the Sixth Ministry said a little frivolously, looking at his official uniform, it should be on the sixth grade, and at this age, he is either in a high position in the imperial examination, or he has a deep background.

Among the carriages where many Zaifu are present, I am afraid that the latter is the majority who dare to speak.

"It shouldn't be far, right?" The official who judged before said with a little uncertainty.

"Where do you think the boss is going now?" Zhao Xin suddenly became interested and asked softly.

"This ......" Ye Qingchen hesitated slightly, if it was calculated according to half an hour, according to the speed of the previous train experiment, it would be at least about 50 miles, but is this possible?

During the experiment, it was completely unobstructed, and it was an empty car, with so many people occupying, could it be the same?

As soon as Zhao Xin saw Ye Qingchen's expression, he knew what Ye Qingchen thought in his heart, heavy cars and light cars, they are definitely different, but it also depends on what heavy cars and light cars are.

In the end, when the train was put into use, it was changed, the weight of the carriage was reduced a lot, and now the average per carriage is just more than 100 people, the Northern Song Dynasty of this era, there are really not many fat people, in this case, a person is at most fifty or sixty kilograms, more than 100 people, that is, five or six tons, this is heavier than the empty car, but it cannot be called a heavy car, and the adjusted train will be smoother, and the speed is obviously a little faster.

"I guess it's almost time for Chen Liu?" Zhao Xin said calmly.

Ye Qingchen's expression was stunned, Chen Liu was not far away, but it was not close, it was so soon.

It seems to confirm Zhao Xin's statement, and the speed of the car began to decrease at this time.

Unlike the lowering of a high-speed car, which is slow and even requires the brakes to be pulled, this car, as soon as the horse's speed begins to drop, the speed of the car drops significantly.

At first, only Ye Qingchen and Zhao Xin noticed, and then, almost everyone noticed that the speed of the car was decreasing.

Some officials were very strange, and even blurted out what happened, if the horse couldn't run, Ye Qingchen was stunned, didn't he really arrive in Chenliu Town.

Between Bianliang and Yingtianfu, there is a total of 300 miles of railway line, six stations have been set up, out of Bianliang, the first is Chenliu, this place is not far from Gyeonggi, but it is not close, even if it is some errand officers of Kaifeng Prefecture, if you want to send some letters to Chenliu Town, you also need to hurry up for half an hour to arrive.

The fast horse of a single horse, sitting in the train, such a smooth chatter and tea, is also half an hour, and it will arrive, can this be the same, comfort is a completely different choice.

In the past, when the official and the old man traveled, they all took an ox cart, from Bianliang to Chenliu, I am afraid that it would not take a day.

The speed of the train decreased significantly, Ye Qingchen looked out the window, because the speed decreased, the scenery outside the window began to gradually become clear, it seemed to be farmland, but with the gradual slowdown of the speed, some houses appeared in front of him, he was stunned, because the scenery in front of him made him very familiar, isn't this Chen Liuzhen?

Rubbing his eyes, it seemed that everything in front of him was like an illusion, but this town, which was managed more by the Third Division, had been to it at least ten times, and he was very clear about these houses, and even the tallest building in the town, Chen Xuexue Temple, he also mentioned it.

Because of the reduction in the speed of the train, many officials also turned their attention to the outside, at first, there was no attention, isn't it just the destruction of farmland and villages, these are not difficult to see in Gyeonggi, and even those broken houses, they are nothing, aren't they just a bunch of materials together?

But looking at it, some officials looked at those houses very familiarly, after all, the speed of the car is getting slower and slower, and they can be seen more clearly.

Chen Liu is very close to Bianliang, and among these Beijing officials, there are many who have been to Chen Liu, and even some of them have been here a lot.

It's not a small lively town, which is not uncommon here in Gyeonggi, but Chenliu is a relatively special place because it has a huge school temple.

When the school temple appeared in front of them, a young official shouted out in a lost voice: "Isn't this to Chenliu!" ”

"Chen Liu, it's impossible, it can't be so fast!"

Chenliu is a town in Gyeonggi, and because of its proximity to Tokyo, it is also quite prosperous, but it is more than 70 miles away from Bianliang, which is too fast, right?

"That's the temple of learning, it's very tall and unique, I can be sure that there is no such temple in Gyeonggi anywhere else!" An official who was familiar with Chen Liu said loudly.

It's not a confirmation of one or two people, as long as you have been to Chenliu, you know that this is a big landmark.

But because of the certainty, everyone was dumbfounded, this is too fast, 70 miles, this is only half an hour, this speed is the speed of a fast horse, but they didn't feel the bump at all, it was like sitting at home for a while, and then they arrived.

Is it an illusion, this is what most people think, in the middle, Ye Qingchen stood up, walked quickly to the door, and was about to get off the train, but was blocked by the train service staff, and after asking, he knew that this was indeed Chenliu Station, the first station from Tokyo to the west, but the time spent here was only 250 breaths, and half of it had just passed.

Stop, this Ye Qingchen knows, the main purpose is to change horses, of course, if it is put into operation, there will be some others, for example, some passengers who get on and off the train, these will use this time, generally about 250 breaths, and when they arrive at Yingtianfu, there should be more, because it is the terminal station.

There are still some doubts in his heart, but Ye Qingchen doesn't care, anyway, the train is still leaving, if you have any questions, wait until Ying Tianfu arrives.

After Ye Qingchen sat on the seat, because of the answer with the conductor just now, he didn't deliberately lower his voice, they all heard it, it was sure that it was Chen Liu, the only trace of doubt left before was completely gone, it was really beyond their imagination, and there was a buzz in the carriage, and everyone couldn't help but discuss why it was so fast.

Of course, some people have raised a question, it won't be true, a few hours, or even faster, to be able to reach Ying Tianfu.

It was just a joke before, but after 70 miles in half an hour, then more than 2 hours, at most 3 hours, to Yingtianfu, it's not a big deal, right?
