The train driver in the courtyard

Chapter 529: An inconspicuous screw

Chapter 529 An inconspicuous screw
Yang Yi doesn't care about Wang Mudan's future, let alone marry Wang Mudan.

It's just that if Wang Mudan is fired, he can only return to Sentie.

Wang Peony can be said to be a charming peony flower, and Yang Yi was naturally reluctant to let it go.

Wang Mudan said angrily: "It's Li Aiguo. He is the captain of our study class. Zhou Mingyi informed me today."

Wang Mudan repeated Zhou Mingyi's words and said through gritted teeth: "That Li Aiguo is a bandit. When we were in Daheigou, Liu Xiaodong just smoked in front of him, and he pushed back unreasonably. "

Wang Mudan is a very open-minded woman, and she has never been afraid to talk about her old acquaintances.

Yang Yi is good at this, so he also knows about Liu Xiaodong.

Yang Yi was full of sympathy for this fellow man.

If Liu Xiaodong hadn't done that, he probably wouldn't be together with Wang Mudan now.

"I'm asking you, what should I do?"

Seeing that Yang Yi kept smoking without saying a word, Wang Mudan pulled his arm anxiously and said coquettishly.

"I've given everything to you, you can't just sit back and watch."

"It's Li Aiguo again! This guy is deliberately trying to get in trouble with me."

Yang Yi gritted his teeth and took two long puffs of cigarette.

"It's just that now I'm just a train driver, and Li Aiguo has a very good relationship with Mr. Duan, so this matter is really difficult to handle."

"It's hard to handle? When you carried me to the train and asked me to fiddle with the gear lever, why didn't you think it was hard to handle!"

Wang Mudan's whole body exploded when she heard this. She jumped off the bed naked, without even putting on her clothes. She pointed at Yang Yi's nose and said: "Yang Yi, I tell you, I am not one of those little girls who are beaten by you." After eating and wiping it all, I can only shed tears.

If you dare to stand by and let me be sent back to Sentie, I will never forgive you. "

Seeing that she was really angry, Yang Yi quickly sat up, took her into his arms, and pulled the quilt to cover her.

"Mudan, don't worry, little Li Aiguo is no match for me. I am the best train driver in the Qianmen locomotive depot."

"You really have a way?" Wang Mudan pretended not to believe it.

Yang Yi raised a sneer at the corner of his mouth and said: "As a train driver, it is very easy to cause problems with the train!"

"You are going to tamper with the train brakes."

Although Wang Mudan is not a train driver, she also knows a lot about trains.

Especially after the locomotives in the front locomotive depot were prepared, they were all parked at the station.

There was no one guarding the station at night, so no one would notice him even if he tampered with it.

Instead of feeling scared, she became excited and leaned on Yang Yi's face and took a sip.

"I just know that you are capable. It is best to destroy all the brakes so that when Li Aiguo drives tomorrow, he will be unable to stop the train and run off the track.

There are at least two thousand passengers on a passenger train. Even if half of them die by then, Li Aiguo will have to take a bullet. "

Yang Yi seemed to have no psychological burden for killing more than a thousand people, so he put out the cigarette butt and threw it to the ground.

"You are so stupid."

Being teased out of anger, Yang Yi turned over and pressed her under him.

"The train driver must check the condition of the locomotive before every trip. The brakes are the first thing to check, as they are easily exposed."

"Then what are you going to do?"

"Let me taste it and tell you."

"Disgusting~"

A burst of dissolute laughter floated out from the crack of the window, which seemed particularly harsh in this silent night.

The bright moon hanging in the sky was covered by a group of dark clouds, and the capital fell into darkness.

Three o'clock in the morning.

The super machine that had been noisy all day in the capital finally slowed down.

Schools, factories. These parts fell into silence.

The locomotive depot, which operates important components 24 hours a day, also became quiet at this time.

Only occasionally can one hear the whistle of a freight train coming in for maintenance.

Passenger locomotives that have undergone simple maintenance and repairs are parked at the station, like sleeping giants, waiting for the arrival of dawn.

In the warm night breeze, everything seemed so quiet and peaceful.

Sudden.

A figure suddenly appeared beside the track in the distance, walking towards this side quietly.

This person seems to be familiar with the situation in the station.

The tracks in the station were intricate and full of tunnels. He could reach the station only by the hazy moonlight.

The figure shuttled between the locomotives for a while. Seeing that no one was nearby, he immediately picked up the flashlight from his arms and shined it on the serial number of the locomotive.

After searching for seven or eight motorcycles in a row, I still couldn't find the target. The figure seemed to be a little impatient, and the speed also increased a bit.

"Found it, this is the front of train 131."

The bright flashlight beam shone on the serial number, and a sneer appeared on the figure's lips.

He turned off the flashlight, looked around, saw no one around, and quickly ducked under the car.

After a while.

The dark figure climbed out from under the car, and walked outside with his hands behind his back as if nothing had happened.

"Hey, why don't you go to bed so late?"

A voice came from behind, and the white paper light bulb hanging on the station buzzed twice, giving off a flickering light.

Yang Yi's whole body suddenly stiffened and his throat raised to his throat.

Waves of warm wind blew by, but it made him shiver involuntarily, and his heart was filled with fear and uneasiness.

The footsteps in the darkness were like drumsticks beating on his heart, waking him up.

He quickly put the wrench into his trouser pocket, turned around, and saw a young man standing opposite.

The young man was wearing a railway uniform instead of a security department uniform, and he felt relieved.

"You are the correspondent. What is your name?"

"Master Yang, my name is Yan Jiecheng. You have forgotten that I helped you arrange accommodation when you came to the locomotive depot."

Yan Jiecheng took a flashlight and shined it on his face.

That not-so-handsome face looked a bit scary in the dark, especially the small eyes that were inherited from the third uncle. They were blinking, which was even more scary.

Yang Yi, who had just breathed a sigh of relief, was startled. He waved his hand and said, "Yes, yes, yes, temporary worker Yan Jiecheng, the little errand boy in the locomotive depot."

Yan Jiecheng is now a regular employee, and he is often responsible for delivering Duan Li's notices. Anyone who sees him has to call him Officer Yan.

This guy is a temporary worker and an errand boy.

Yan Jiecheng almost lost his temper in anger.

"Driver Yang, it's so late, why are you hanging around?" Yan Jiecheng asked, suppressing his anger.

Yang Yi snorted coldly and said: "Who are you? Do you care? It's you who stayed up late at night. Are you planning to steal something?"

Yang Yi didn't look at Yan Jiecheng with colored eyes. All the workers in the locomotive depot these days were thieves.

Of course, in the eyes of those workers, the locomotive depot is their own home. Is taking their own things called stealing?

"I'm different from ordinary workers!"

Yan Jiecheng also knew this statement, and explained angrily: "I took the initiative to work overtime tonight, which is a sign of positive thinking. If you dare to frame me, be careful, I will take you to the security department."

"Okay, who knows what you are going to do!"

Yang Yi originally slapped a hat on Yan Jiecheng because of his guilty conscience. Seeing that Yan Jiecheng took the bait, he turned around and left humming a ditty with his hands behind his back.

The reason why Yan Jiecheng greeted Yang Yi was because he wanted to build a relationship, but unexpectedly, he was punished and was so angry that he spat and smeared on the ground.

"It is simply wishful thinking for someone like you to want to compete with your patriotic brothers!"

After cursing a few words, Yan Jiecheng gathered his mood and returned to the courtyard happily.

Recently, his relationship with the girl named Yu Li has warmed up a lot, and maybe they will get married in a while.

Early the next morning.

Because he had a driving duty, Li Aiguo got up from bed early as usual.

Chen Xueru had already prepared breakfast at this time.

Two large white noodle steamed buns, seven scrambled eggs and an extra-large omelette.

"It's too luxurious to eat so much so early in the morning."

Li Aiguo washed his face and sat at the table.

Chen Xueru brought up a bowl of stick noodle porridge with a smile and placed it in front of him.

"You can have enough energy only if you eat enough. I heard from Zhao Gang's family that a woman's ovulation lasts for several days, so you can still have a lot of energy at night."

What does it mean to be like a wolf and a tiger? This is it!

Li Aiguo has also seen the world.

But I have never thought that Chen Xueru, a simple girl, would talk about these things as if she were speaking ordinary words.

In fact, I feel relieved when I think about it.

Giving birth to children is a sacred thing, there is nothing to be ashamed of.

It's just that this looks down on Li Aiguo. Even if we only eat black corn, we can still farm for seven or eight days.

But this omelette is so delicious.

Seven eggs were swallowed into the stomach, and two white flour steamed buns were eaten.

Eat and drink enough and feel full of energy.

Li Aiguo put down the empty plate, picked up a towel to wipe his mouth, picked up a canvas bag, and pushed his bicycle out of the house.

At this time, the courtyard was very lively.

The second uncle chased Liu Guangfu with a stick.

Liu Guangfu was often chased and beaten, and he was tempered.

Now the two short legs were rubbing together, as flexible as a monkey, and disappeared in the blink of an eye.

"Are you beating the children again, second uncle?" Li Aiguo greeted loudly with a smile.

"Isn't it just idle time? Uh."

Liu Haizhong was panting from exhaustion. Seeing that he couldn't catch up, he stopped and pointed angrily into the distance.

"This little brat is getting more and more outrageous. I just gave him a few words of scolding. Guess what, he added some ingredients to my wine jar while I was asleep!"

"Additional ingredients?"

"That's the one you know."

Li Aiguo blurted out: "Child urine?"

Liu Haizhong blushed slightly and nodded.

"Huh, it's such a trivial matter, why do you need to be so angry? Second uncle, children's urine is a traditional Chinese medicine. It is cool in nature, salty in taste, and has the effect of nourishing yin and reducing fire!" Li Aiguo said seriously.

“It does taste a bit salty”

Liu Haizhong seemed to realize something. He quickly adjusted his collar, frowned and said, "Aiguo, you didn't lie to me, did you?"

"You can go to the community hospital and ask Dr. Xiao Ding." "That's not necessary, I still can't trust you."

Liu Haizhong was suddenly overjoyed and whispered: "Since boy's urine is Chinese medicine, then the jar of wine is medicinal wine, and there is no need to pour it out."

"Patriot, thank you."

Liu Haizhong was delighted with a pot of medicinal wine and quickly ran home.

From a long distance, he shouted at the top of his lungs: "Old woman, that urine wine is medicinal wine and a good thing. Don't throw it away."

Li Aiguo looked at his excited back with a smile on his lips.

This time, a pot of old wine was saved in the bangs. It seems that we have done a good thing again.

It seems that he can change his name to the good man Li Aiguo in the future.

The good man Li Aiguo greeted his neighbors all the way to the front yard.

"Yan Jiecheng, go to work." Li Aiguo shouted towards Yan's house.

Recently, Yan Jie became a convenient person to talk to Yu Li and moved back home from the locomotive depot dormitory.

Because he didn't have a bicycle, Li Aiguo took him with him every time he went to work.

After a while, Yan Jiecheng yawned and walked out of the room.

"It's so early, patriotic brothers."

His face was obviously haggard, and his eyes were sunken into their sockets, dry and dull.

A pair of dark circles can make you go to the zoo and pretend to be a giant panda.

"Did you work overtime again last night?" Li Aiguo pushed on his bicycle and walked out of the compound.

Yan Jiecheng sat in the back seat and smiled awkwardly: "Yes, I have been under a lot of financial pressure recently."

Although Yan Jiecheng is now a formal employee, he does not have a fixed position. He is regarded as a handyman in the locomotive maintenance section and does not receive job allowances.

The work is easier, but the income is more than half less than when I was a coal bearer.

But he had to pay full living expenses every month and save money to go to the park with Yu Li. Money was really tight.

Although there is no overtime pay for working overtime in a section, the monthly allowance is 2 yuan higher than that of ordinary workers.

Li Aiguo also knew about this situation, told him to pay attention to his health, got on his bicycle and drove towards the locomotive depot.

Halfway there, Yan Jiecheng sat in the back seat and whispered: "Patriotic brother, the new Yang Yi is going to compete with you for the lead, so you have to be careful."

"Why did you mention this all of a sudden?"

"I met Yang Yi at the station last night when I was getting off work. I originally wanted to chat with him, but the good guy showed off his skills in the big car, but he was criticized."

"Yeah."

Li Aiguo didn't pay attention, and the two of them chatted all the way to the Qianmen Locomotive Depot.

It was time to go to work, and the locomotives on the station were getting ready to set off.

Streams of steam emerged from the black roof of the car, majestic, and the whistle roared. Against the background of the blue sky, it looked like a bustling oil painting.

A steam locomotive passed by Li Aiguo. The complex connecting rod structure under the car revealed the unique beauty of machinery, which was fascinating.

Li Aiguo has watched it countless times, and he still can't help but stop every time.

It wasn't until Huang Jing came over with a canvas bag and asked him to go to the meeting that she straightened up.

After the morning meeting, it means that an ordinary and busy day begins again.

Li Aiguo, Cao Wenzhi, and Lao Zheng came to the venue chatting.

Team leader Wang, who was in charge of maintenance in the maintenance workshop, had already been waiting aside and handed over the maintenance order.

"Driver Li, everything was normal with the locomotive yesterday, so it didn't go into the maintenance workshop. Now the coal and water have been added and it's ready to go at any time."

He picked up the list, looked at it twice, and handed it back.

Li Aiguo turned to look at Huang Jing.

"Go down and check it out."

The weather is hot now, and the bottom of the car is not ventilated. It is not a good idea to get out of the car to check.

Some people may think that this is abusing the apprentice.

But when some driver students nearby saw this scene, they all cast envious glances at Huang Jing.

Train drivers are responsible for the lives of thousands of passengers.

Learning to drive a train is a serious and long process.

Some of these trainees have been stokers for a year or two and have never touched any train parts except the furnace.

They are eager for Huang Jing to gain the trust of the train driver.

Huang Jing did not expect that Li Aiguo would hand over the task to her today.

Nodding excitedly, he slipped under the train.

Huang Jing followed Li Aiguo's instructions yesterday and checked whether the springs were bent and whether the vehicle underframe was cracked, broken, or bent out of shape.

She also picked up an inspection hammer and pounded everywhere to make sure nothing was abnormal. Huang Jing took out her notebook from her jacket pocket and began to check the red paint on the screws one by one.

At this time, Li Aiguo lit a cigarette, squatted on the platform and started smoking comfortably.

"Driver Li, Huang Jing has just gotten into the car, and you asked her to start working. Are you too anxious?"

Lao Zheng looked at Huang Jing struggling to crawl under the car, and he couldn't bear it, and reminded him with a smile.

Li Aiguo said: "This girl has the talent to be a train driver."

"She is a lesbian after all." Liu Qingquan also felt that Li Aiguo was too impatient.

Li Aiguo said: "On the train, there are only two types of train drivers, one is the excellent train driver, and the other is the coward train driver. There are no female drivers."

Hearing this, Lao Zheng and Liu Qingquan were immediately speechless.

After all, accidents don’t happen just because you are a female driver.

Similarly, if a female driver makes a mistake, the train will not derail just because of her gender.

Equality between men and women cannot just be paid lip service to.

A few people were chatting when a voice came from under the car.

"Master, this screw seems to be a little loose. Would you like me to tighten it now?"

Hearing the crisp sound, Li Aiguo frowned and put the cigarette butt on the ground and stamped it out.

He had checked all these screws yesterday, and there were no signs of looseness at all.

The locomotive was parked all night, how could something go wrong?
Huang Jing saw Li Aiguo get down, picked up the flashlight and shined it under the cylinder.

The screw is hidden inside, surrounded by exhaust pipes, and can only be seen clearly with the help of a flashlight.

I saw that the paint surface on the screws was pitted and the screw caps almost fell off.

It can be expected that with just a few more bumps, the entire screw will fall off the component.

It's just such an important screw. Li Aiguo personally checked it yesterday. Why is this happening?
"Master, this screw is covered with paint. It looks very important. What is it used for? Let me screw it in first."

Huang Jing saw something wrong with Li Aiguo's expression, so she stopped smiling and picked up the wrench to tighten the screws.

Li Aiguo stretched out his hand to stop her.

"There's something wrong with this screw, don't tighten it yet."

Li Aiguo pointed to the pole fixed by screws and explained: "This pole is connected to the drain valve in the driver's building. Once the screws fall off, the drainage will not respond."

Hearing this, Huang Jing's expression suddenly changed. The car was already very hot, but she couldn't help but shudder.

As a trainee driver, although Huang Jing cannot learn to drive a train for the time being, she still knows everything about the important matters of a train driver.

People often see fast-moving steam locomotives. In addition to the white smoke coming from the boiler at the front of the locomotive, sometimes the bottom of the cylinder in front of the locomotive's moving wheel will "chichichichichi" rhythmically spray small jets of steam horizontally from time to time.

Especially when reversing, going down a long slope, or slowing down, this exhaust sound appears more frequently.

This is actually the train draining water, and the train driver is pushing the drain valve to release the water condensation in the cylinder.

Now that there is a problem with the drain valve, it will definitely be dangerous while driving.

Huang Jing is a smart girl, and she instantly realized that the screw was somehow loose.

"Master, is it possible that someone deliberately loosened the screws?"

"It is indeed possible."

Li Aiguo was a man who cherished his life. Seeing this situation, he immediately told Huang Jing not to touch the screw.

He got out of the car. Liu Qingquan and Lao Zheng had been waiting for a long time.

"Driver Li, haven't you finished the inspection? It's almost time to leave."

Li Aiguo's face was serious: "Please call Master Cao over."

"Aren't you always responsible for maintenance?"

Liu Qingquan still wanted to say a few words, but when he saw Li Aiguo's expression, he realized something was wrong and hurriedly ran towards the coal warehouse next to him.

Cao Wenzhi and a few old friends were bragging there. After all, with an apprentice like Li Aiguo, he no longer had to worry about driving.

Seeing Liu Qingquan running over, he asked a few questions and then rushed over with two other comrades from the driver team.

"Patriot, I heard that there was an accident on the train? It can't be possible. There was no maintenance last night. If it's just a minor problem, we can just hold on."

Cao Wenzhi was a little anxious at this time. After all, the driving time was coming soon, and he might miss the finish line.

"The problem is not big, the key is that it is very strange and there may be sequelae."

Li Aiguo signaled Cao Wen to get under the car, pointed to the screw cap and told him his suspicions.

Cao Wenzhi, an old train driver, broke into a cold sweat on his forehead.

"This matter is serious. We need to notify the workshop and Duanli immediately."

Cao Wenzhi realized the seriousness of the problem and stopped driving. He sent someone to call workshop director Liu and team leader Wang, who was responsible for the maintenance work, to the platform.

After Director Liu checked the screws, he frowned and said, "Master Cao, the screws are loose now. Can't we just tighten them? Is there any need to waste time here?"

Cao Wenzhi sighed and said, "If it were that simple, Patriot wouldn't have informed me."

Seeing that Director Liu still didn't understand, he emphasized his tone and said: "

The drain valve is an important safety device in the locomotive.

In a steam train, the high-temperature and high-pressure steam in the cylinder drives the piston (piston) to move, which is transmitted to the driving wheels, thereby pushing the locomotive and driving the train forward.

Theoretically, there will be no water condensation in the cylinder, but in practice, high-pressure steam will also condense into water during the work process.

Especially when the train is idling or decelerating, the frequency of movement of the train decreases, and the water condensation gas will sink along the cylinder and occupy the space at the bottom of the cylinder.

The cylinder of a steam locomotive is actually a pressure vessel, and the water condensation gas occupies the space. As the engine reciprocates work, the air pressure in the cylinder will gradually increase.

Timely removal of cylinder condensate is a mandatory requirement in steam locomotive operating procedures.

If the condensate water is not drained away in time according to the operating procedures and high-pressure steam is input forcefully, the condensate water in the well-sealed cylinder will have nowhere to go.

The water condensation gas will produce a water hammer effect under the continuous forceful push of Qingtao.

Even the high-strength and high-temperature-resistant cylinder cover cannot withstand the huge impact.

In the worst case, the cylinder head may be broken, and in the worst case, the entire front of the car may be blown up!

Now it can be determined that this screw was unscrewed by someone, and the other person's purpose was only to cause trouble for driving.

How can you be sure that the other party only moved this screw and did not do other tricks in the steam engine?

In case the other party hid a detonator in the tender truck and put the explosive package under the truck.
Once the train is loaded with passengers, don’t you understand what will happen in the end? "
