Chapter 538 Drought
"Okay, I'll go back and do some calculations. Thanks to you for giving me thousands of immortal talismans before, the Ministry of Industry has no shortage of manpower now. I can do what you said." Liu Zhimu was stimulated. It can be imagined that in the future, it will be very difficult. Over a long period of time, you will be "spending money like water".

What a big undertaking!

"All work must go hand in hand. Don't build the railway, and there will be no trains. Once the trains are built, no one will drive them, and no one will dispatch them. All aspects must be studied and prepared." Liu Xinqi reminded.

"Train! This is a good name. It's a car that can run when it's on fire. From now on, this type of steam locomotive will be called a train."

Liu Xinqi did not expect that Liu Zhimu would catch this name. Later generations have always called it a train. Even if it is an electric locomotive, it is still called a train, so he said it smoothly.

"What a name, Train, it sounds so domineering." A craftsman next to him praised.

"It sounds much better than a steam locomotive."

"Yeah, the train..."

"The train is back!"

While everyone was chatting, the steam locomotive ran around and returned to the starting point.

The craftsmen stepped forward and began to load the freight car.

The deconstruction of the truck compartment is very simple, it is a flat plate on several wheels, and there are guardrails around the flat plate.

"Would you like to go up and sit and run around?" Liu Zhimu invited.

"Okay, okay." Liu Xinang agreed directly, then ran towards the truck compartment and jumped into the compartment.

There were some horses placed on the carriage. Liu Xinqi did not sit down, but stood on the floor of the carriage with great interest.

Liu Xinqi and others also boarded the carriage.

Since the locomotive hadn't turned off, it quickly started moving again after adding some coal.

After a dozen breaths, the speed increased to 120 miles per hour ([-] kilometers per hour). Standing on the car, you can clearly feel the oncoming wind.

"It's so stable!" Liu Xin'ang praised.

The smoothness of this train is definitely not as smooth as the passenger trains of later generations, but it is much better than today's horse-drawn carriages.

Happiness is all about comparison.

"If this carriage is made closed, and some fixed chairs are placed inside, it can transport people. For long-distance travel, I think most people will choose to take the train instead of a passenger carriage." Gao Yuandao .

"This is a good idea. I only thought about transporting goods before, but I never considered transporting people. When you say this, it feels very feasible." Liu Zhimu was inspired.

"It's definitely feasible! Transporting people is lighter than transporting cargo. The carriages can be made longer and can pull more. Kitchens and toilets can be installed in the carriages, and even beds can be installed in some carriages." Liu Xinqi also reminded.

The "Design Notes" did not record it so clearly, but Gao Yuan reminded him.

"This is good. You can also make some small boxes and charge rich people a lot of money." Liu Zhimu said.

There was a slight hatred for rich people in his tone, and he didn't realize that he was now considered a rich man.

During the chat, the train circled the test site again, which was really fast.

When it was almost reaching the end, the locomotive in front began to brake and slow down, and the carriage behind it was carried by inertia at the connection with the locomotive in the middle.

The creaking sound of steel colliding could be heard, which was very harsh.

"Doesn't this carriage have brakes?" Liu Xinqi asked.

"No, the brakes need power. This carriage has no power." Liu Zhimu replied.

"Then have you ever considered that if a locomotive pulls twenty fully loaded freight cars, can a small locomotive be able to brake when the time comes to brake? Can the connection points between the carriages be sustained?" Liu Xinqi asked.

Liu Zhimu frowned after hearing this.

The teaching materials taught by Liu Xinqi clearly recorded inertia, acceleration and deceleration. After a simple calculation, Liu Zhimu found that if the carriage behind did not have its own independent brake, it was indeed unrealistic to rely solely on the locomotive in front to brake.

The locomotive is expected to be pushed off the track by the car behind. "What should we do? Do we need to equip each carriage with a steam engine or manual braking? This information transmission is also a problem and is not realistic." Liu Zhimu thought of two ideas, but he rejected them.

"Wind movement can be considered. The wind pressure is transmitted to the carriage behind through the pipe." Liu Xinqi then talked about some principles of wind movement.

Liu Xinqi himself did not know the specific structure and wind pressure suppression, and had never been exposed to it before.

I just know that there were pneumatic drills in later generations, and trains were braked through air ducts. The principle should be similar.

"According to this principle, the wind pressure in the entire duct system should be the same, so the same pressure can be controlled to all the wheels behind, which is the same braking force." Liu Zhimu tried to understand.

"That's right, this will not put too much pressure on the connecting rod in the middle." Liu Xinqi replied.

"Wonderful."

"According to this principle, if we use wind pressure power, we can install many machines on one pipeline at the same time." A craftsman drew inferences from one example.

"Wind pressure is weak after all." A craftsman said.

[Whether the wind pressure is weak or not depends on the tightness of the pipeline. 】Liu Xinqi thought in his heart without interrupting everyone's burst of inspiration.

"Weakness also has its uses. Not all manufacturing procedures require large power." Another craftsman added.

"It's not necessarily weak, right? We tested the explosive before, and the wind pressure generated by the explosion of the explosive was not weak."

...

Liu Zhimu and Gao Yuan looked at each other, wondering what was wrong with these people and why they suddenly became so excited.

"Let's go back." Liu Xinqi said.

The researchers are in a state of burst of inspiration, and it is best not to disturb them, otherwise they will not recognize their relatives.

"Ok."

The two of them followed Liu Xinqi out, while Liu Zhimu stayed behind without sending anything away.

……

On April [-], Xu Zhong came to Liu Xinqi's office with a solemn expression.

Usually this look means there is bad news.

"What's wrong?" Liu Xinqi asked.

"Diting made statistics and found that Jingdong East Road, Jingdong East Road and Hebei East Road have received very little rainfall since January this year. Last winter, there were only a few light snowfalls. The same is true for other roads in Hebei." Xu Zhonghui reported .

"Oh?" Liu Xinqi was confused: "Why didn't I hear the relevant report from the Government Affairs Council?"

"The Government Affairs Council has noticed it and is organizing people to help themselves, digging wells, diverting water from rivers, etc. However, their data is not as timely as ours," Xu Zhong replied.

Just as he was talking, Luo Cheng walked in from the door.

"Is it convenient?" Luo Cheng asked when he saw Xu Zhong in the office.

"Convenient." Liu Xinqi nodded and motioned for Luo Cheng to come in.

"I want to report something important to you." Luo Cheng held a stack of information in his hand.

"Drought?" Liu Xinqi asked.

"Yes, you know it all." Luo Cheng looked at Xu Zhong, Liu Xinqi should have known it from him.

Xu Zhong turned out to be the housekeeper of the Luo family. Luo Cheng knew Xu Zhong and knew that he was in charge of the intelligence agency of the Xinghan League.

"Just found out." Liu Xinqi picked up the report and looked through it.
