Because no one has experienced how a steam train starts, everyone sat quietly to welcome the start of the train.
Everyone only heard one voice.
"Start the steam engine! Close the clutch!"
Everyone sitting in the first carriage heard the sound of adding coal.
Then I saw Li Min operating in the cab.
In front of him was a pile of cold machines, then he pulled the valve and moved another switch.
It feels very powerful! It’s really a layman’s way of watching the fun, but an expert’s way of looking at it! Everyone can only watch the fun!
This operation is incomprehensible to people, and people who don't understand think he is crazy.
What are you doing there?
In fact, these operations are necessary.
Unlike riding a horse, where you can control it left or right by simply pulling the reins, a train is more complicated. It takes a while just to start.
Li Shimin stood up, looked at Li Min's movements in front of him, and fell into deep thought.
Taking advantage of this opportunity, he suddenly asked: "What is a steam engine and how does it work? I don't understand it very well!"
Li Yun explained: "A steam engine is actually a coal-fired steam boiler. The combustion of coal turns water into high-pressure and high-temperature steam. These steams have great energy and can ride some heavy objects. When the steam is sprayed on the engine cylinder
When it is connected, it will push the piston, and the piston will drive the machine to run. If it is connected to the train, it can make the wheels move forward."
Li Yun's words made everyone stunned.
Although I don’t understand what’s going on, I can only assume that it’s very powerful.
It turns out there are so many wonderful things here.
Compared to trams, steam locomotives have more incredible things!
It can last for a long time without external power supply, as long as there is coal and water!
Regarding steam, everyone was shocked to find out that it can also have this function.
Why didn't I think of it before?
I have to admire how awesome Li Min’s brain is!
Li Yun then introduced others.
And suddenly there was a loud noise.
Woo woo woo...
The whistle sounds.
Everyone was frightened.
With such a loud sound, the interior of the carriage began to become chaotic.
All the concubines wanted to go down, but only Concubine Yang and Empress Changsun protected Li Shimin, for fear that someone would do harm to him.
At the same time, the people outside were also frightened.
They have never heard such a sound.
This kind of behavior was noticed by Li Min who was in the back. He wanted to laugh but didn't dare to.
Especially Li Shimin's expression, he looked a little frightened.
That's very funny.
"Your Majesty, be careful!"
Queen Changsun said.
Obviously, they overreacted.
I thought someone was going to harm Li Shimin!
Not only that, the generals in the rear car couldn't sit still anymore, and they also wanted to rush to the front.
Everyone's confusion lasted only a short time.
It wasn't until the train started moving that the whistle became quieter.
Only then did everyone relax a little.
At the same time, Li Yun came forward to explain:
"Don't panic, everyone, that's the sound of a steam whistle. You can understand it as the sound of boiling water! This whistle sound is also a signal sound. Different meanings can be judged by the sound. The whistle sound just now is the sound of starting, and the long sound
Short sounds and spaces between them all represent different meanings."
After what Li Yun said, everyone finally understood.
It turns out that there are so many doorways in this train.
How did Li Min come up with these things?
Genius! What a genius!
There is no one in the world who is more talented than Li Min!
Shengtang Group has given them too many shocks since its establishment.
What's more, what's more
Sounds started coming from under the car!
Then the train started to speed up slowly.
Moved, moved.
There is such a saying in everyone's mind.
The train is really moving.
At the same time, Li Shimin was shocked to death.
You know, just now he saw a lot of cement behind him, but he didn't expect that the train just pulled them away.
In the future, we can really build a railway to Taizhou, which would be a great thing.
In fact, this steam train is still rudimentary, and the future electric trains will be awesome and can reach speeds of hundreds of kilometers per hour.
But Li Min can't create it now. After all, it is a profound thing.
Looking at the slowly moving scenery around them, everyone looked very excited.
Concubine Yang said: "This train is much more comfortable to ride on than a carriage. There are no bumps! It's just smooth! It's really shocking."
Everyone was surprised by how smooth the train was. Although it was not as good as an electric car, it was not far behind.
Li Min's behavior made the train advance a thousand years.
Let the entire Tang Dynasty people enjoy the convenience brought by this means of transportation in advance.
It also made Li Shimin's thinking become more in-depth.
At the same time, his status will be elevated again.
From then on, he was the only one in the Tang Dynasty. Anyone could be killed. Only he had to live on. His existence would make the Tang Dynasty stronger.
The train was still a little slow at first, and everyone was puzzled, but they didn’t ask why!
The people outside shouted excitedly.
Someone started running after the train!
What's more, what's more
As the train continued to speed up, the scenery continued to recede.
Everyone's novelty energy came back again.
They were lying by the window, looking at the distant scenery, looking particularly comfortable.
The life of a wealthy family is just like this.
In the roar of the train, the speed gradually increased, and the speed became faster and faster.
The common people are gradually unable to keep up!
Look at the people outside!
Li Shimin said: "I think the speed of the train can be compared to the speed of horses!"
Li Yun said: "Father, the speed of the train completely crushes the speed of the horses!"
"What? Crush?"
"Yes, crushing, because the speed of the horse cannot remain constant, but the train can, and it is faster!"
Queen Changsun asked: "When will the power of the train be exhausted?"
Li Yun pointed to the coal and said: "As long as it and the water are constant, the train can keep running!"
Everyone found it incredible.
"There are many mines near Chang'an for this coal. I will order people to mine it when the time comes!"
Li Shimin said.
This is what he can do.
Because energy is the source of driving.
Without energy, there is nothing.
At this time, Li Min's voice came from the loudspeaker.
"Everyone, please note that the train will travel on the railway for half a stick of incense. Please cherish the time on the road and take a look at the surrounding scenery!"
Everyone was shocked again. It turned out that this train was so advanced.
There is something like a speaker on top of it.
Does that mean that as long as you are in the cab, you can inform everyone of relevant matters?
As the train was running, someone pushed a cart with many fruits on it every once in a while.
Ask everyone if you want to eat.
This kind of service makes everyone very comfortable.
