The train driver in the courtyard

Chapter 323 Heading to Kailuan, Li Aiguo has a clear idea
Watched the unloading of the rollover car on site.

The leaders of the Railway Research Institute were shocked by the speed and safety of unloading.

The first trial transportation is also on the agenda.

Because the clean coal inventory at the Qianmen Locomotive Depot has been sufficient recently, there is no task of allocating coal.

Section Chief Xing of the Locomotive Maintenance Section had to apply temporarily to the Main Section to purchase a batch of unplanned clean coal.

Generally, this kind of unplanned purchase requires research before making a decision.

However, under the personal supervision of the old director of the institute and Liu Guozhang, the Qianmen Locomotive Depot received the deployment plan that morning.

The quantity of clean coal allocated this time is 2000 tons, the allocation point is Kailuan Coal Mine, and the allocation method is self-pickup.

The next day.

In the section chief's office.

Duan Chang Xing handed the deployment plan to Li Aiguo: "Comrade Patriot, this transportation task is very difficult. Do you want to reconsider it?"

Li Aiguo knew what Duan Chang Xing meant.

According to design standards, the load of a train is 60 tons.

The Qianjin train only carries 24 rail cars. If you want to transport 2000 tons of clean coal back, it will definitely have to be overloaded.

That's nothing.

As the saying goes, a train that is not overloaded is not a good train.

Overloading has been taken into consideration during the design and construction of the carriages.

The most critical issue is that from Beijing to Kailuan Coal Mine, one needs to pass through the Tangxu Railway on the Qiluan Line.

Tangxu Railway is the earliest independently built railway line in China.

It was built during the Westernization Movement. It starts from Eshan and ends at Xugezhuang, with a length of 9.3 kilometers.

At first, donkeys and horses were used to pull sports cars, and in the second year, locomotives were used to pull them.

In the subsequent time, with the expansion of Kailuan Coal Mine, the Tangxu Railway was gradually extended, starting from Qidaoqiao Station on the main line of Jinshan Railway and ending at Luanxian Station on the main line of Beijing-Harbin Railway.

The railway bed collapsed due to blind mining of underground coal by the Kaiping Mining Bureau (the predecessor of the Kailuan Mining Bureau).

In addition, the railway has a history of hundreds of years and is often run over by heavy-haul trains, so the line conditions are very poor and accidents often occur.

Li Aiguo understood Duan Chang Xing's concern, stood up and straightened his chest and said: "It is precisely because of the difficulty of the transportation task that it is even more important for me, the designer, to drive the car myself!"

"If there is danger and all the train operators retreat, how can our railway industry develop?"

Duan Chang Xing's eyes narrowed when he heard this.

He slowly stood up and saluted Li Aiguo.

"Comrade Patriot, I will arrange for a rescue train to be waiting at all times. If an accident occurs, don't act recklessly!"

Of course Li Aiguo would not act recklessly.

New technology does come with significant risks.

But the dump truck technology he brought out has been tested in later generations.

It's purely a dimensionality reduction blow.

Soldiers are very fast.

The locomotive depot quickly contacted the Kailuan Coal Mine and coordinated with the Eshan locomotive depot to conduct unified dispatching of trains along the line.

According to the dispatch schedule, Li Aiguo needs to leave in the afternoon.

He received the task and wanted to take a short rest in the staff dormitory.

After exiting the door of the section leader's office, he was hit by the cool breeze and slapped his forehead suddenly.

We are married and have a wife!
Li Aiguo got on his bicycle and hurriedly returned to the courtyard.

Chen Xueru was sitting in front of the sewing machine working hard. When she saw him coming in, her face was full of surprise: "Brother Patriot, aren't you going home for lunch?"

"We have a mission later."

Li Aiguo walked over, held her fair and tender little hand and said, "If this mission goes well, it may take two days."

"Two days, so long"

Chen Xueru's eyes dimmed instantly.

Finally, he bit his red lips and said, "Go ahead, I'll be waiting for you to come back at home."

Before she married Li Aiguo, she was prepared for her husband to travel frequently on business.

In fact, train drivers like Li Aiguo who run passenger lines can go home every day.

Every few days, there is also a day off.

That kind of long-distance freight line driver is often away from home for most of the month.

Chen Xueru is a contented girl. After realizing this, she immediately became happy.

"Just wait, I'm going to serve you dumplings. I heard Aunt Liu say, get the dumplings on the bus, and get the noodles off."

"What do you mean?"

Li Aiguo sat on a chair and looked at the pretty figure working in the kitchen.

"Eat dumplings when you get in the car and noodles when you get home. Only in this way will you have good luck." Chen Xueru turned her head and pursed her lips with a smile.

"."

Li Aiguo did not blame Miss Chen for this little feudal superstition.

After all, caring leads to chaos.

After eating dumplings and drinking dumpling soup, Li Aiguo looked at the big clock and saw that it had just reached twelve o'clock.

Follow this task schedule.

The train departs at 02:30 in the afternoon, and there are still two hours of free time.

After some calculation, the time is just enough.
Li Aiguo smiled, took his smooth wrist, and pulled out Miss Chen who was busy in the kitchen.

".I'm busy."

Miss Chen was stunned at first.

When he was pulled into the room, he finally understood. His cheeks flushed brightly. He stood up shyly and fell into the rough man's arms. He said with a smile on his face: "You, you have to drive the train later to say goodbye. Don’t be tired.”

"It's okay, our train driver is as strong as an old cow."

two hours later.

Li Aiguo, who felt refreshed, pedaled hard with his legs and quickly arrived at the battlefield of the locomotive depot.

Duan Chang Xing from the Locomotive Maintenance Section, Liu Guozhang from the Research Institute, Deputy Director Zhang with a donkey face, Liu Qingquan and Lao Zheng from the 131 crew were already waiting there.

There were many employees gathered around, including Yan Jiecheng.

Duan Chang Xing and the director of the freight workshop are doing ideological mobilization work for Liu Qingquan and Lao Zheng.

"You are all old comrades. You should be aware of the dangers of driving this time and the difficulty of the task. If anyone wants to back down, you can raise it now."

"Captain Duan, it's my honor to be able to cooperate with Driver Li in driving. Only cowards are afraid of me!"

"Even if I risk my life, I will transport the coal back."

Both of them clenched their fists tightly, looking like they were fighting for their lives.

Seeing Li Aiguo coming over, Duan Chang Xing waved to him: "Aiguo, I specially transferred your old partner here."

"Thank you, Chief Duan." Li Aiguo nodded gratefully.

If you team up with familiar comrades, the success rate of this mission will be higher.

Liu Guozhang called Li Aiguo over and introduced him to the people accompanying him this time.

Accompanying the vehicle is a testing team responsible for testing the technical data of the dump truck while it is driving.

The team leader was a researcher named Liu Mingshan, who was a close associate of Deputy Director Zhang of the Railway Research Institute.

Dong Gong serves as the deputy team leader, and the remaining three team members are all from the research team under Deputy Director Zhang.

"Patriot, I know Liu Mingshan fairly well. He is the kind of person who likes to stab people in the back. Be careful."

Liu Guozhang's tone was full of apology.

When selecting members of the testing team, Liu Guozhang also expressed different opinions to the old director.

Only in order to take the overall situation into consideration and to test the quality of the rollover car, the old director agreed to Deputy Director Zhang's proposal.

However, in order to balance both parties, it was agreed that Dong Gong would accompany him.

Li Aiguo understood Liu Guozhang's difficulties and said confidently: "Teacher, don't worry, I designed the things myself and I have a plan in mind!"

The two chatted for a while.

We’ve almost arrived at the starting point.

Director Zhang of the maintenance workshop personally led the maintenance workers to inspect the forward train inside and out.

"Driver Li, there is nothing wrong with the train. If something happens on the road, come back and kick my head like a ball." The old maintenance man said loudly, waving his hammer.

The dispatcher who had been waiting nearby handed over the dispatch form with both hands.

Li Aiguo was about to reach out to take the dispatch table when a loud voice came from beside him: "Brother Aiguo, you will definitely not have any problems driving this time."

Turn away.

I saw Yan Jiecheng waving a torn shirt stained with soot, jumping around in the crowd and shouting loudly.

Nima
Three black lines suddenly slid down Li Aiguo's forehead.

Before I even left the house, someone planted a flag.

Lao Zheng experienced what happened last time he went to Jincheng and was very sensitive to planting flags.

At that time, regardless of Duan Chang's presence, he rushed over and slapped Yan Jiecheng hard on the forehead.

"Boy, what nonsense are you talking about!"

Yan Jiecheng was slapped, but now he came to his senses and said quickly: "Master, I didn't mean it, I just did it"

"You kid, be less naughty in the future."

Lao Zheng had taught Yan Jiecheng how to shovel coal, so how could he not know what Yan Jiecheng was thinking, so he waved his hand and turned back to the train.

At this time, the departure time has arrived.

Liu Guozhang stepped forward: "Patriot, this time it's up to you."

"Don't worry, teacher!" Li Aiguo nodded heavily, and then took Liu Qingquan and Lao Zheng onto the locomotive.

Also accompanying him was a technical team composed of Liu Mingshan, Dong Gong and three researchers from the Fifth Research Group.

Including the three crew members, there were eight people.

Fortunately, the forward locomotive was equipped with a tender, and the technical team could sit on a small bench at the door of the tender.

After placing the comrades of the technical team, Li Aiguo followed the procedure, signed the book handed over by the dispatcher, and waved to the people below.

Then he yelled: "Burn the fire!"

"Burn the fire Lou!"

Lao Zheng, who had been waiting for a long time, stepped on the door of the furnace, picked up the coal shovel and sprinkled coal inside, and the flames in the furnace rose.

Li Aiguo stared closely at the air pressure gauge. After the pointer jumped, he loudly ordered: "Comrade co-driver, pay attention to the lookout!"

Liu Qingquan retracted his head from outside and reported: "Everything is normal at the front, comrade the driver."

Li Aiguo took a deep breath.

Slowly push the joystick, and the high-pressure steam in the boiler flows along the pipe into the steam room, pushing the steam piston, and the black train wheels begin to slide forward along the rails.

Woo woo

Eat like crazy, eat like crazy, eat like crazy
The train was like a beast descending the mountain, braving bursts of black smoke, running wildly along the black railway, and finally disappeared into the bright sunshine.

Everyone watched the train disappear before turning and leaving the battlefield.

"You kid, don't act smart in front of your leaders from now on."

The leader of the coal-carrying team waited for the leaders to leave, then stepped forward and took Yan Jiecheng's arm and lectured him.

Yan Jiecheng rubbed his forehead and muttered somewhat depressedly: "Li Aiguo and I live in the same compound. Is it wrong to care about him?"

Seeing Yan Jiecheng's harsh words, the team leader stopped talking to him and pointed to the coal in the bunker: "You work overtime today to load coal for train No. 21. You won't be allowed to leave until you finish loading."

Yan Jiecheng: "."

The distance from Beijing to Kailuan Coal Mine is only more than 200 kilometers, but the railway line is very complicated.

You need to enter the Jingshan section of the Jingha Line first, then transfer to the Tangxu Line at Qidaoqiao Bandao Station.

Then pass through Xugezhuang, Jijiatun (line station), Eshannan, Kaiping, Wali, Guye, Beijidian, Leizhuang, and finally arrive at Kailuan Coal Mine.

The train left the capital and ran along the railway line.

Because the forward train is the latest development and the equipment is relatively advanced in this era, it is very comfortable to operate.

Li Aiguo seemed to be on vacation.

The only people who were unhappy were the members of the fifth research team.

Under the guise of inspecting the trains, they required the trains to stop every ten kilometers and inspect them before they could run again.

This request may seem unreasonable, but in fact it makes no sense at all.

Li Aiguo, who is also a researcher, knows the vehicle inspection procedures and regulations well.

With the implementation of this new technology, even if the train is stopped for inspection, it only needs to be inspected every [-] kilometers or when passing through the switching station to ensure the safety of the train.

In the wilderness of these days, in addition to wild wolves, there were also people carrying hunting rifles.

It seems unsafe, but it is actually very dangerous.

As a train driver, Li Aiguo wanted to ensure the safety of the train, so of course he disagreed.

Those guys suddenly became anxious.

In particular, Liu Mingshan, the leader of the vehicle inspection team, rushed to Li Aiguo's side, waved his hands loudly, and shouted for Li Aiguo to stop immediately.

Otherwise, when he returns to the institute, he immediately complains to the Qianmen Locomotive Depot for not cooperating.

I guarantee that Li Patriot will be severely punished.

Old Dong was a little embarrassed when he saw this scene.

He is also on the vehicle inspection team.

If he tried to stop him at this time, Liu Mingshan would definitely report it to Deputy Director Zhang.

Deputy Director Zhang is a sinister guy.

Jie Shi will definitely use this as a reason to attack Liu Guozhang.

He could only cast apologetic eyes on Li Aiguo.

Li Aiguo is a train driver.

I have never seen such a scene before, and I can still be intimidated by a receptionist.

With just a wink, Lao Zheng rushed up with a coal shovel in hand.

The big coal shovel whirred in the small locomotive.

"Young man, you dare to play tricks with our train drivers, you are tired of living. My old man has been burning boilers for most of his life, but he has never burned a living person. Do you want to be the first?"

Don't tell me.Old Zheng already had a fierce look on his face, and now his face was covered in soot, with only two big bloodshot eyes like bells showing, making him look even more ferocious.

Liu Mingshan and the team members were restrained at that time.

Finally, I accepted the 'suggestion' to check the train again when stopping at the crossing station.

I was defeated in the first contest.

Liu Mingshan could only squat at the entrance of the water tanker with a few researchers and sulk.

Before departure this time, Deputy Director Zhang specifically talked to them.

Even though there were no clear instructions, a few people could understand that this meant finding fault with the situation.

These people were technicians in the old train inspection institute before liberation.

At that time, the requirements for inspectors were high and their wages were low. They only earned five yuan a month, but jobs were in short supply.

why.

Just because you can eat and get cards.

At that time, if you wanted to sell the equipment to the Engineering Department of the Railway Bureau, you had to obediently send it to these inspection personnel.

After liberation.

No one dares to send money anymore, and they can only drink from the northwest wind.

Fortunately, we were able to enter the research institute because of the lack of technical personnel.

It's just that as the country cultivates a large number of technical talents and more and more talents enter the research institutes, the status of these old people is getting lower and lower.

In particular, Liu Guozhang, a leader with strong roots and integrity, suddenly became the first deputy director, which aroused their vigilance.

That's why he launched an attack on Li Aiguo without hesitation as soon as he got in the car.

I just didn't expect that Li Aiguo would use unreasonable methods to deal with them.

This made Liu Mingshan, who had already made up a lot of excuses, confused.

You reason, but the other party doesn't listen!

Here, Li Aiguo felt at ease.

While chatting with Liu Qingquan and others, he was controlling the train.

"Old Liu, Old Dong, what you said just now under the train are true?"

"Of course!"

Liu Qingquan retracted his head and said loudly: "Even if the railway track in front is broken, as long as the locomotive department gives an order, I will dare to rush forward."

"Me too!" Lao Zheng echoed loudly.

Liu Mingshan squatted there and couldn't bear it anymore after hearing these words.

He said sarcastically: "You guys have no knowledge or culture, you are just rough guys, you are not yet in the organization, and your ideological consciousness is not high. You only pay lip service and are falsely positive.

If they were really in danger, they would probably escape faster than the other. "

"what are you"

Lao Zheng felt insulted, so he picked up the coal shovel and tried to hit him on the forehead.

But was stopped by Li Aiguo.

"Old Zheng, we must convince people with reason."

"Tell this university student researcher why our locomotive depot workers dare to fight for the locomotive depot."

Lao Zheng took back the coal shovel, spat at Liu Mingshan's feet, and said loudly: "Boy, please listen carefully.

Before liberation, I worked as a stoker in the locomotive depot. At that time, I was bullied and my wages were often withheld.

After liberation, the locomotive depot changed its color, and I truly felt like I had become the master.

Follow the regulations of the locomotive depot.

If I die, my daughter-in-law, my son, and my whole family can become formal workers and receive a large pension.

I am disabled, and the locomotive depot will pay for hospital fees and nursing fees to support me for the rest of my life.

They will also help my son arrange work.

What else do I have to be afraid of? "

boom.

The coal shovel was hammered into the iron plate at the bottom of the car.

Lao Zheng's eyes were fearless, his face was red, and he looked like he was ready to fight at any time.

Liu Mingshan stopped talking.

But he still doesn't understand.

Can you sacrifice yourself for the sake of your son, your wife, and the maintenance section?

These workers are really stupid.

After a small episode passed.

The atmosphere inside the train was solemn.

The monotonous sound of eating, eating, eating filled the air for half an hour.

Li Aiguo was planning the driving route in his mind, and Liu Qingquan's voice came to his ears: "Report to the driver, there is Qidaoqiao crossing station 500 meters ahead, prepare to stop and wait!"

Because trains are temporarily scheduled, they need to stop and wait for the trains in the section to clear before they can transfer to the section.

This is one of the reasons why temporary freight transport is more likely to cause accidents.

Li Aiguo sounded the whistle and slowly pushed the small valve, and the speed of the train gradually dropped.

At this time, the commander of Qidaoqiao Switching Station had already raised a red flag with both arms above his head and waved it sharply to both sides.

"Reporting to the driver, comrade, the switch station ahead has issued a stop signal, 200 meters away."

Calculating the speed silently in his mind, Li Aiguo dropped the speed immediately.

click
With a crisp sound of brakes, the long train stopped accurately in front of the stop line.

The old switchman saw that the black wheels were exactly aligned with the white lines. He was stunned and did not put down the flag in his hand.

It wasn't until Liu Qingquan shouted that he realized what he was doing.

He inserted the small flag into his work belt and ran over and said loudly: "Hey, your train driver's skills are not as good as they are! They are not like those damn train drivers at the Qianmen Locomotive Depot who always exceed the line by more than 200 meters every time they stop. I was so scared that my corrugated lid almost softened."

Because this parking will take at least half an hour.

Li Aiguo also came down from the side door to rest, spread his hands and said, "We are from the locomotive depot at the front door."

Old switchman: "."

He scratched his head and smiled awkwardly: "That's because their skills are too flawed."

Li Aiguo took out a cigarette from his pocket, handed it to the old switchman, and asked: "Uncle, how long do you need to park this time?"

In fact, Li Aiguo had already obtained the timetable before departure.

It's just that the plan doesn't change quickly. Accidents may happen at any time within the railway section, so the parking time is constantly adjusted.

"I estimate it will take three or four hours."

The old switchman is on duty at the switch station all year round, and it is rare to see a few living people.

After contacting Duan's dispatch room again, the conversation started.

He smoked a cigarette and pointed at the train: "Comrade driver, what are you pulling?"

"Go to Kailuan to load coal." Li Aiguo felt like a coal driver in later generations.

"Coal? Don't fool me." The old switchman said in a loud voice: "I have been guarding the switch here for seven or eight years, and I don't know anything about what's going on inside!"

Pointing to the railway line in the distance with his black and thin fingers, he said loudly: "This is the busiest railway line in the country. It can pass dozens of trains every day. In order for your train to pass, at least ten trains have to pull over. stop."

Seeing that the old switchman didn't believe it, Li Aiguo didn't want to explain more, but went to Xi Li'er next to him to release the water.

After shaking and twisting, when he turned around and came back, Dong Dong and the vehicle inspection team were recording various data.

"Old Dong, there's more..."

Li Aiguo couldn't remember the names of those people, he only knew that they were under Liu Mingshan's command, and waved to them: "And you guys, hurry up and release the water.

Later we have to drive continuously for three hours.

This is a new car. If anyone dares to pour water out of the window on the way, don't blame me for throwing him out. "

Dong Gong came from the grassroots level and was accustomed to applying fertilizer to crops in public.

He put away his notebook and strode to the fields where there was a roar.

The members of the fifth research group were all genuine college students before the liberation, and some of them had eaten foreign food, drank foreign wine and danced in foreign countries. They felt that Dong Gong's behavior was uncivilized.

Liu Mingshan looked at the old switchman: "Old man, is there a bathroom here?"

"What is a bathroom?"

Liu Mingshan: "."

Liu Qingquan also saw at this moment that Liu Mingshan was not in the same group as Dong Gong and Liu Guozhang.

The people nearby cheered: "If you use foreign words, it's just a pit."

"We are in the wilderness here, do we need that thing?" The old switchman threw the cigarette butt on the ground and pointed to the side: "Whatever!"

A few people are a little embarrassed.

They murmured for a while and decided to walk a little further to the back of the switchboard station hut.

"Hey, there are wild wolves here." The old switchman reminded.

Several people's faces suddenly turned pale and they all stopped.

Liu Mingshan said with a sneer: "Forget it, I won't go, we are not in a hurry anyway."

Li Aiguo smiled, lit a cigarette, took a deep breath, and looked contented.

Dong Gong came over and whispered: "Patriot, we don't need to argue with people like them."

"Old Dong, I'm not as generous as you." Li Aiguo spat out a cloud of white mist and said, "If anyone dares to offend us and doesn't get back on his terms, we won't have the right ideas."

Dong Gong didn't know whether to laugh or cry: "You are quite generous."

"Hey, we are workers, we are not afraid of anyone!"

Li Aiguo smiled, stood up, and returned to the train.

He leaned back on the steel chair and narrowed his eyes.

We may have to drive the train all night later, so we must take advantage of the temporary stops to get some extra sleep.

Liu Qingquan and Lao Zheng also drove frequently. They knew this and followed the example and lay down on the chairs.

I don't know how long it took.

"Driver Li, there was a call from the dispatch room just now. You can pass."

There was a shout outside the window.

The old switchman came out of the switch station, picked up the green flag behind him and waved it.

Li Aiguo rubbed his eyes and saw that the sky was getting dark. He used the trigger to turn on the locomotive lights on the locomotive, and then opened the locomotive standard lights on both sides of the body.

After finishing the preparations, I didn’t forget to say thank you to the old man.

Li Aiguo was just about to start the train when a few sticks of corn were stuffed outside the window.

"Sticky jade millet! I chopped it from the ground this morning! It's just finished, you guys have a try."

"Old man, thank you very much."

Li Aiguo was not polite, took the corn from the window, and put it on the stove to heat up.

The train started here, and Li Aiguo took out a pack of large air force from his pocket and threw it down: "Old man, please."

By this time the train had run far away, and it was no longer possible for the old switchman to throw the big air force onto it again.

I could only hold my cigarette and watch the train leave.

"This little driver is really a fastidious person."

The corn at this time is not fully mature yet, and the corn kernels are all green, so it can only be used for frying, not roasting.

The cooked corn tastes completely different from roasted corn.

There is less of a burnt aroma, but more of a natural fragrance.

There were only three corns in total. Two were given to Liu Qingquan and Lao Zheng. Li Aiguo broke the remaining corn in half and handed it to Lao Dong.

As for Liu Mingshan and the others, they could only watch with envy.

Smelling the fresh fragrance and hearing the continuous chirping sounds, several people quickly realized a problem.

They didn't bring lunch boxes.

"Driver Li, how shall we eat?" Liu Mingshan raised his wrist to look at his watch and said with a smile.

"Eating? Of course." Li Aiguo picked up a few lunch boxes from under the seat.

Just taking a look inside the canvas bag, Li Aiguo burst into laughter.

The bag was given to him by Duan Chang Xing before leaving.

There are a total of four beef kidney lunch boxes inside.

In other words, in addition to the private crew, there is also Dong Gong, but not Liu Mingshan and the others.

It seems that Duan Chang Xing is also a temperamental person.

"These are prepared by the locomotive depot canteen for us rough guys!" Li Aiguo placed the lunch box on the top of the stove to heat it.

The meal prepared by Duan Chang Xing was so sumptuous.

Crystal clear white rice, a golden fried egg, a chicken leg, and stir-fried radish and Chinese cabbage.

After a while, the entire driver's building was filled with a strong fragrance.

The scent was like a big hand reaching into Liu Mingshan's mouth, down his throat and into his stomach, grabbing his shriveled stomach and kneading it into a ball.Shaked hard again.

The incandescent light bulb hanging from the roof of the train swayed from side to side as the train vibrated.

The dim yellow light flickered, making Liu Mingshan's face flicker.

Liu Mingshan's lips trembled, and he could no longer put on airs. He smiled and said: "Driver Li, we forgot to bring our lunch boxes. Can you please..."

"No!" Li Aiguo said with a straight face and refused directly.

This time even the old Dong didn’t persuade me.

If the conflict between Li Aiguo and Liu Mingshan was just a dispute between Liu Guozhang and Deputy Director Zhang, it would be easy to resolve.

He knew that Li Aiguo's temperament was not the kind of person who would be unreasonable and unforgiving.

But Liu Mingshan just said something different, looking down on the workers in the locomotive depot.

This directly touched Li Aiguo's bottom line.

Old Dong knows.

This little train driver has always been proud of his status as a worker.
