"Eldest nephew, you say, should you put the steam engine on the train?" The uncles are in a hurry.

This steam engine is used on a lathe, and it has reached the level of practicality, but why doesn't the eldest nephew press it on the train?

"Uncles, I'm more anxious than you, but, this steam engine, do you see its power is enough, I tell you, its power is seriously insufficient, and now even the lathe has not reached the maximum input, you don't see, this lathe is slightly larger, it will be suffocated, so it still has room for improvement, besides, this is just a test model, not a practical model, and even said, this thing can only be placed in a museum, or he can be used in the coal mine."

Yes, it is used in coal mines, due to the arrival of Yang Heng, some coal mines have entered the time of deep digging in advance, so that the underground water level is relatively large, so there are many people to seek Yang Heng's help, that is, if the coal mine does not pump water out, it will not be able to continue to work, if the output of coal is delayed because of this matter, then the order of the building materials factory is delayed, they are not responsible.

This, it's not that they threaten Yang Heng, it's really this thing that happened, and in this era, no one can really solve the pumping problem of this large amount of water.

So, Yang Heng remembered that this steam engine, when he remembered the initial research in history in his previous life, was designed for coal mine pumping, so okay, just restore it to its original function, it is enough to pump water, and it also saves a lot of components.

In this way, as Datang's mining business, with the support of Yang Heng's skills. Another big step forward. Every coal mine. There are several steam engines, and even Yang Heng has produced a supporting underground rail mine car system for them, so that one by one the underground coal mines have begun to form.

This can be regarded as the first improvement of the steam engine, not to change the advanced, but to the original, especially as a steam engine. It doesn't even need 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 steam engine gold that the steam engine has earned him.

Due to the deep digging of the coal mine, Yang Heng also gave some knowledge about safety, one is the support in the coal mine, which does not need Yang Heng's special guidance. Another is ventilation, which is to prevent the hazards of some gases. All the hazards, Yang Heng has compiled a booklet, called Coal Mine Safety Precautions, which is given away for free, but if they comply with it or not, Yang Heng will not know the way, and Yang Heng does not want to know the road, accidents, and safety precautions, which are often made up after the death of the sheep, what, force them to implement.

This is a bit funny, why do you force it, what do you use to supervise, first, you don't have harmful gas detection equipment, second, you have extra people to supervise, what, let the imperial court supervise, if the imperial court can supervise it, then Li Er's emperor is really good.

So, after a few accidents, as coal mine owners, they also really realized the importance of Yang Heng's booklet, not that they cherished human life, but that this accident actually caused the entire coal mine to collapse, if you continue to mine, you will invest a lot of money to continue mining, but if you don't invest money, the agreement is still there, and you will also have to lose a lot of money.

I had an accident, and a lot of people died, so I won't complete the agreement, this is a joke, we remind you, every time you sell you a steam engine, I'll give you a booklet, you say no, then who signed it.

That, for the sake of wealth, they must also abide by some regulations, if they don't comply, then they will waste a lot of wealth, so a forced helpless thing is so complied with, human life, human life in this era is really worthless, even Li Er does not support the death and injury caused by an accident, punish these coal mine owners, Yang Heng, although he is not used to it, but he can't change it, he can only value human life in his own home.

But fortunately, whether it is for wealth or for human life, after a few accidents, there are also a few stewards who were directly executed by the master's family, and there will be a lot fewer accidents in the future, some accidents, which are really unavoidable, even if it is Yang Heng's previous life, there are some accidents that will happen unexpectedly, this is a real accident, this, it cannot be avoided.

"Xuewen, it's been so long, why are you still using a horse to pull this car, didn't you build a steam engine, and it seems that you have sold a lot of steam engines to coal mines, you don't want to delay the affairs of the emperor just to make money." Li Er once again came to the horse-drawn train.

Now, this line has been built for nearly 80 miles, so that there are more people who come to travel on it, and even more passenger transport projects, and the number of sections as trains has also increased to four, that is, the horses pulling the carriage have also increased a lot, however, this has reached the limit, if the distance is lengthened, the number of sections increases, it is unlikely.

"Your Majesty, this is not a single thing, as a coal mine, if there is less coal, our steel production will be less, less steel, and the manufacture of this rail will not be able to keep up, so this is a series of things, and it can even be said that it is a sharpening knife and cutting wood. Besides, after we sold so many steam engines, the skills of the steam engines became more and more mature, and some of the workers were trained to a very high level. ”

"Cheng, let's do this in your way, I don't know much about techniques, but I warn you, you must not delay the affairs of the emperor, because of the matter of building the academy, I have delayed it for you for half a year, this should be enough, right?"

"Enough, enough, this time next year, your majesty will be able to sit on the train driven by power, that is, the real train, your majesty has not felt, this time to take the car, it is much better than the last time, you must know the road, this is the third generation of the carriage system, whether it is the brake, or the chassis, or the quality of the carriage, there has been a great improvement, and the sound insulation is also a lot better, your majesty has not paid attention, today did not hear the sound next door, or, I will open the door to listen to your majesty."

Sure enough, as soon as I opened the door of the box, I heard the noise outside, some laughing, some shouting, and even drinking.

"Well, yes, your change is not small, it won't be changed specifically for me." "I'm sorry, Your Majesty, this shout is really not for the change you made, the people who want to sit in these boxes are some high-level people, and even below the fourth grade, we will not let them in, and as ordinary people, there is naturally that big carriage to sit people, there are more than 100 seats in it, however, the attendance rate is really not very full, although the price is very low, but there are still not many seats."

This ordinary seat, Yang Heng is really not used to make money, but to ask for a copper plate every ten miles, but that's it, there are not many people to sit, and most of the people who sit are some businessmen, because it is a light car, so there are restrictions on the luggage carried by people who sit in the car, and it is also charged, and even, when you get on the car, you need to weigh it, so it is mainly to control the load capacity of a carriage, Yang Heng is afraid that the chassis of the car will be crushed, this horse-drawn car is like this, one needs a light chassis, and another needs to be light. When the steam engine is officially used, these chassis will be phased out again.

…………

"Everyone, our drawings have been changed again, I hope you must study it carefully, make it carefully, I have made a promise to His Majesty, in the second half of next year, we must let the steam engine be loaded on the train, so that the train will really become a train, and the horse-drawn train will be eliminated, do you have confidence." "Yes, with the owner's drawings, we can't make them well, so are we still human, and the treatment given to us by the owner is also good."

As a result, the second upgrade plan of the steam engine was officially implemented, and this improvement was considered to be a preparation for the car, but it was not the initial model of the car, that is, this was still a test product. (To be continued......)
