"Oh, let's talk about your previous test." Huo Gang said with a smile. He was very interested in this.

"Yes, we are more like technical verification of the first generation of steam trains, which is to amplify the steam engine we use in daily life and put it on. However, after we amplify, we found that although the amplified steam engine actually provides increased power, the increase in the amount of power is simply insignificant, as the weight of the steam engine itself increases," Lu Feng said immediately.

"Later we thought of the pressure you mentioned, that is, in a closed environment, the higher the temperature of the steam and the greater the pressure, the higher the temperature it can provide, the greater the power the steam engine can provide, but the structural components and sealing performance requirements are very high."

"If it weren't for the rivet method you proposed and the related sealing method, it would be difficult for us to make this." Lu Feng said seriously, "Our first steam train could only pull things as heavy as two carriages, and the speed was not fast."

"We operated the second and third generation steam engines according to what you mentioned in high temperature and high pressure steam, and optimized the internal structure of the steam engine. Its power has been greatly improved, and it can pull the weight of up to twenty carriages."

"But that... it overturned later." Lu Feng scratched his head, then smiled embarrassedly and said: "The main reason is that we have problems with the design of the bottom wheels, and the center of gravity is unreasonable, which leads to the driving straight line, but because of a little bit of unbalanced weight, it overturned directly."

"Their power was temporarily enough at that time. We tested it more than a dozen times before we found a more suitable method to balance the wheels."

"It was not until the fourth generation of steam train that we successfully ran it smoothly, but the rails at that time were only 3 kilometers and the length was not enough, so we couldn't test its speed, so we could only test its stability." Lu Feng quickly introduced to Huo Gang.

Although he only reduced it briefly, Huo Gang could hear that they must have encountered many difficulties in this process, but these problems can be overcome one by one. Obviously, this is already very amazing.

"Now we are using the fifth generation. For the time being, we have added 10 cars behind it today. If these cars are full, they are about 50 carriages." Lu Feng introduced Huo Gang to the steam train in front of him.

Huo Gang nodded. He had seen the 10 cars pulled behind the back of the car. These cars were not big, at least not like all cars in later generations were standard length cars. This is not urgent for the time being, because the era of this thing is developing, and the size of the car is verified based on the technology of the train's chassis and wheels.

It is obviously not possible to be too big or too small. Huo Gang has no data on this thing. He doesn't know how long the car was in later generations. It was about ten meters long for a car, but this data is not accurate. Even if he knows it, it doesn't make sense. Whether the chassis can withstand it is the most important thing.

The bearings and sealing of the wheels are also very important. Huo Gang doesn't know how their wheels are developed, so he will not give a specific data and let Lu Feng and the others test them personally.

At present, the length of these cars is only about 4 meters long. The width of the track is 1,600 mm, which is 1.6 meters, and the width is about doubled, which is only about 3 meters. This is what Huo Gang tested carefully.

However, these cars are not very tall, so they don’t pull a lot of things. If you conduct a post-load bearing test, it should be OK.

"Well, it's good, let's go and try it." Huo Gang pointed directly at the carriage and said, because the part behind the coal-pulled carriage behind the locomotive was used for carrying people, so Huo Gang lifted his legs and walked up.

"Chief, no, this thing has not been tested and the safety cannot be guaranteed." Lu Feng and the others were immediately shocked and spoke quickly.

"It doesn't matter, someone always needs to ride the first time, and I believe you have also tested it before, and this is probably the first time you won't drive too fast." Huo Gang said with a smile.

The others looked at each other and immediately hesitated, but Huo Gang did not give them a chance to hesitate, but instead lifted his legs and walked in.

When they saw Huo Gang entering, everyone else soon followed him, including Huo Zheng and other guards. "You can start right away when you are ready." Huo Gang said.

"Yes!" Lu Feng took a deep breath and walked directly forward through an aisle next to him. This aisle was designed on the outside of the coal-pulling carriage, and you can go directly from the manned carriage to the front front of the carriage.

There were already several soldiers waiting there on the front of the car. In fact, the train had already started to burn, otherwise it would take a long time to preheat alone.

Now that he heard Huo Gang's words, Lu Feng went to command himself.

There are not many people in this carriage, but there are also many. Now there are at least 30 people standing here. Apart from the ten guards, the remaining people include Huo Zheng, Annuo, Yang Wu, and Sun Er and other technicians, as well as Mingyue, Shi Wannian, Bosa, Longtuqizhi, Liang Shuo and others.

The reason why these people came together was that in addition to giving them more knowledge, they wanted to give them a warning, especially the three people, Shi Wannian, Bosa, and Longtuqi Branch. The Longtuqi Branch had just joined. Although the entire Yanqi Kingdom had already obeyed Huo Gang very much, mainly because the people at the bottom were very obedient.

As for the original nobles on the surface, Huo Gang just confiscated the assets in the treasury of Yanqi, and their private assets were not moved at all.

However, the news from some unknown place was left behind, their assets such as gold, silver, houses, etc. were left behind, but the land, cattle, sheep and other assets were voluntarily handed over.

Huo Gang gave them face to them because they were so aware of their identities and gave them certain shares from the Dahan textile business.

Huo Gang didn't tell them the amount of this share, because the state-owned textile business of the Han Dynasty was established from the beginning, to put it bluntly, it was to redistribute property to these surrendered families and nobles, including the former nobles of the Tongluo tribe, etc.

However, the profits of the textile shop are too high. They were given 1% in the early stage, and the latter was an extremely terrifying number, so Huo Gang did not give a specific number, but would directly pay them dividends every year.

This number will not be fixed for the time being, but after the end of this year, they will probably be given a suitable proportion and then the appropriate shares will be fixed directly, because this year is the year of explosion, and the profits of textile shops can almost be calculated.

Although it will definitely increase in the future, it will increase. Since you surrender and surrender for no reason, it is reasonable to give them some money.

Compared to Huo Gang's understanding of the entire train, Long Tuqizhi and others did not understand at all. They looked like a huge steel monster like steam engines. Although they were shocked that the great man could create such a huge steel monster, they had already seen a lot of such things.

I have seen many steel parts that are larger than this since I came to Industrial City. Compared with these, buildings such as reinforced concrete are even more shocking, so they accept them quickly.

But for them, the train was completely unaware of it.

So, when they all got into this carriage, they saw Huo Gang sitting down, and everyone naturally sat down. Shi Wannian hesitated for a moment and asked directly: "Chief, what is this train? Is this long train a car?"

Shi Wannian's question made everyone else see it, such as Huo Zheng, Mingyue and others, all looked curious. Although they knew more, Huo Gang never told them.

To be precise, many people who came today actually don’t know what the train means, and even Annuo doesn’t know it. It can be imagined that although Yang Wu was born from Annuo’s subordinate, he still can keep confidential work.

"The train is the main means of transportation for our next generation. It is the same as a carriage, but it can transport more things at once and faster. The most important thing is that it is a machine and does not require rest." Huo Gang did not hide it, but explained it to them simply.

"Chief, do you think this steel lump will move?!" Long Tuqizhi almost raised his eyes. Although the others were so exaggerated, everyone was a little confused. Will this thing move?! Are you afraid that you are not teasing me?!

They just saw it outside. I'm afraid this thing is not ten thousand pounds or even heavier. Can you make such steel lumps by yourself?!

"Of course, what am I lying to you? Tell Lu Feng, and you'll start when you're ready." Huo Gang had already heard a sound of deflation coming from the front.

This sound is used by the steam train to control the intake valve and the exhaust valve, because the steam engine enters the two gas storage chambers from steam, then pushes the piston to move, and then moves the piston from reciprocating linear motion through the connecting rod to turn into circular motion.

In this process, which gas storage chamber first intakes air means whether the last wheel of the steam engine rotates forward or reverses. This is very important, which means that the steam engine can install a locomotive in each of the front parking spaces, so that the train can run at both ends.
