"Big nephew, do you think you should load the steam engine onto the train?" The uncles were anxious.

This steam engine has been used on the lathe and has reached a practical level, but why didn’t my eldest nephew put it on the train?

"Uncles, I'm more anxious than you, but, do you think this steam engine has enough power? I tell you that its power is seriously insufficient. Now the lathe has not reached the maximum input. You haven't seen it. If the lathe is slightly larger, it will be held back. So, there are still some improvements. Besides, this is just a test model and is not a practical model. Even this thing can only be placed in a museum or used in a coal mine."

Yes, it is used in coal mines. Due to Yang Heng's arrival, some coal mines entered the deep digging in advance, so the underground water level was relatively large. So many people came to seek Yang Heng's help, that is, if the coal mine did not pump water out, they would not be able to continue to start construction. If the coal production was delayed due to this matter and the orders of building materials factories were delayed, they would be irresponsible.

This is not because they threatened Yang Heng, but because this thing really happened. Moreover, in this era, no one can solve the problem of pumping water with large amounts of water.

So, Yang Heng remembered that when he first studied this steam engine in his previous life, it was designed for coal mine water pumping. So, it was restored and restored to its original function. It was enough to use it to pump water, and it also saved a lot of components.

In this way, with the technical support of Yang Heng, the mining industry of Datang made a big step forward. Each coal mine had several steam engines. Yang Heng even produced a supporting underground rail mine truck system for them, so one by one, the coal mines that penetrated underground began to form one by one.

This is the first improvement of the steam engine. It is not to change it into the advanced, but to the original. Especially as a steam engine, it does not even require a particularly high pressure, as long as it can pump water, so the production of the boiler can also be simplified a lot. Therefore, since Yang Heng developed the steam engine, this is the first barrel of gold from the steam engine that the steam engine earned him.

Due to the deep digging of coal mines, Yang Heng also gave some knowledge about safety, one was the support in the coal mine. This did not require special guidance from Yang Heng, and the other was ventilation. This was to prevent some gas hazards and all hazards. Yang Heng compiled a booklet called Coal Mine Safety Precautions, which is free to give. However, if they abide by it, Yang Heng didn't know, and Yang Heng didn't want to know that accidents and safety precautions are often repaired after the sheep is lost, and they are forced to enforce it.

This is a bit funny. Why do you force it and what to use to supervise it? First, you don’t have harmful gas detection equipment. Second, you have extra people to supervise it. What, let the court supervise it. If the court can supervise it, then Li Er’s emperor will be really easy to do.

So, after several accidents, as coal mine owners, they truly realized the importance of Yang Heng's booklet. It was not that they cherished human lives, but that this accident actually caused the entire coal mine to collapse. If they continue to mine, they would invest a lot of money to continue mining. However, if they do not invest money, the agreement is still there and they will also have to pay a lot of money. Why do you say that?

I had an accident and many people died, so I didn’t complete the agreement. This is a joke. We remind you whether it is not. Every time I sell you a steam engine, I will give you a booklet. If you say no, then who signed the signing for this signing?

That, for the sake of wealth, they must abide by some regulations. If they do not comply, they will waste a lot of wealth. So, a matter that was forced to be followed wasted. Human life, human life in this era is really worthless. Even Li Er does not support the casualties caused by accidents and punish these coal mine owners. Although Yang Heng was not used to it, he could not change it and could only pay attention to human life in his own home.

Fortunately, whether it is for wealth or human life, after several accidents, several managers were executed by the master's family. In the future, there were a lot of accidents. Some accidents were really unavoidable. Even in Yang Heng's previous life, some accidents would happen unexpectedly. This is a real accident, and this cannot be avoided.

"After studying literature, why have you been using a horse to pull this cart? Didn't you build a steam engine? Also, it seems that you have sold a lot of steam engines to coal mines. Don't delay the affairs of the Supreme Emperor just to make money." Li Er came to the horse-drawn train again.

Now, this route has been built for nearly 80 miles, so there are more people coming to travel, and even more passenger transport projects. The number of trains has increased to four, and even more horses pulling cars has increased a lot. However, this has reached the limit. If the distance is longer and the number of sections is increased, it will be unlikely.

"Your Majesty, this is not a single thing. As a coal mine, if there is less coal, our steel production will be less. If there is less steel, the manufacturing of the rails will not be able to keep up. Therefore, this is a series of things, and it can even be said that sharpening a knife will not delay the chopping of wood. Besides, after we sold so many steam engines, the technology of this steam engine has become more and more mature, and some workers have also trained to a very high level."

"Sure, let's do this in your way. I don't know much about technology. However, I warn you not to delay the matter of the Supreme Emperor. Because of the matter of building academy, I have delayed you for half a year. This should be enough, right?"

"Enough, enough. At this time next year, Your Majesty will be able to take the train driven by power, that is, the real train. Did Your Majesty feel that this time it is much better than the last time? You know, this is the third-generation car system. Whether it is the brake, chassis, or the quality of the car, it has been greatly improved, and the sound insulation is much better. Did Your Majesty pay attention, and I didn't hear the sound next door today. Otherwise, I will open the door and listen to it."

Sure enough, as soon as I opened the door of the box, I heard noisy sounds outside, some were joking, some were shouting, and even some were drinking.

"Well, that's right. Your change is not small. It's not just for me." "Sorry, Your Majesty, this is not the change you made for Your Majesty. When the people who want to sit in these private rooms are all high-level people, and we won't let them in even those who are below the fourth rank. As ordinary people, there are naturally a large carriage to sit in, and there are more than a hundred seats inside. However, the occupancy rate is really not very full. Although the price is very low, there are still not many seats."

Yang Heng really used this ordinary seat to make money, but he wanted a copper plate every ten miles. But that's it, not many people sat there. Most of the people were merchants. Because it was a light car, there were restrictions on the luggage carried by the people who were riding the car, and it was charged. Even if you needed to weigh it when getting on the car, it was mainly to control the load capacity of a car. Yang Heng was afraid that the chassis of the car would be crushed. This was the case with the horse-drawn car. One needed a light chassis and the other needed a light load. When the steam engine was officially used, these chassis would be eliminated again.

…………

"Everyone, our drawings have been changed again. I hope you will study them carefully and make them carefully. I have promised His Majesty that in the second half of next year, the steam engine must be loaded onto the train, so that the train will be truly turned into a train, and eliminated the horse-drawn train. Do you have any confidence?" "Yes, with the drawings of the boss, if we can't make them well, then are we still humans? And the treatment given to us by the boss is also good."

Therefore, the second upgrade plan for the steam engine was officially implemented. This improvement was considered to be a preparation for getting on the car, but it was not the initial model for getting on the car, which means that this is still a test product.
