The train driver in the courtyard

Nothing was gained.

Li Aiguo walked carefully on the broken pieces of the thermos and checked the inside of the carriage carefully, but found nothing.

The structural damage inside the car body only occurred after the collision, which was obviously not the root cause of the accident.

When he walked out of the car, Engineers Zhang and Chen had already completed the inspection of another car.

"Driver Li, we found nothing. We even checked the bottom of the car.

Aside from some axles that were broken in the impact, there was nothing unusual on the floor of the car.”

"Let's check it again to make sure we didn't miss anything. Also, we need to check the rails as well," said Li Aiguo.

The two carriages mounted on the K16 train are old carriages from before the liberation, with a relatively simple structure.

Several people checked again, but still found nothing abnormal.

Generally speaking, the main cause of train overturning is the wheel part.

Although the wheel structures of these two carriages were damaged in the collision.
But after careful measurement with tools, Zhang Gong came to a surprising conclusion:

Even if the wheels are damaged, the stability of the car body can still be maintained and it is impossible to cause the train to overturn.

Although the rails in the derailed section are decades old and have worn out from long-term rolling, they still meet driving standards and cannot be the cause of the accident.

The investigation came to a standstill right at the beginning, and the atmosphere at the scene was as depressing as a huge rock pressing on everyone's heart.

A member of the investigation team walked up to Deputy Section Chief Zhang and whispered a few words to him, who immediately perked up.

He strode forward, with his big round belly, and said loudly: "Since there is no problem with the car body, but the train has derailed, the problem must be with the train driver."

"Mr. Zhang, Mr. Chen, thank you for your hard work. Please sign the document. You are busy with work. I will send someone to take you back."

Deputy Section Chief Zhang's intentions were obvious, and everyone present knew it.
He wanted to put all the blame on the train driver.

But the problem is that there is no problem with the carriages and tracks now.

The accident really happened, so it seems that the only person at fault is the train driver.

The flight attendants and police officers at the scene looked at each other, speechless for a moment.

Zhou Huaiyi was a little unwilling, and stepped forward and said: "Chief Zhang, this matter concerns the future of a train driver. Should we check it again?"

Deputy Section Chief Zhang glanced at him and said, "Old Zhou, because of this train accident, the Beijing-Harbin line has been interrupted for several hours.

This has seriously affected the transportation of materials.

Do you also want to deliberately sabotage the overall economic development like driver Huang did?"

As he spoke, he deliberately emphasized his tone, "Or, were you also involved in Driver Huang's action of sabotaging the train?"

After saying that, he turned his head and looked around at the flight attendants and police officers around him. His meaning was obvious: anyone who pleads for Huang Jing now is Huang Jing's accomplice.

I have to say that Deputy Section Chief Zhang's move was indeed very cunning.

This divisive tactic put Zhou Huaiyi, the flight attendants and police officers in a dilemma.

They really couldn't bear to see Driver Huang being wrongly accused, but how could they bear it if this big hat was put on them?

Zhou Huaiyi, the flight attendants, and the police could only turn their attention to Li Aiguo.
In their minds, the only person who could deal with Deputy Section Chief Zhang at this moment was this role model of the Qianmen Locomotive Depot.

However, what they didn't expect was.

Li Aiguo did not step forward to argue with Deputy Section Chief Zhang as they expected.

Instead, he carried the inspection hammer and walked straight to the rear of car number 14.

He seemed unaware of the tense situation and his eyes were fixed on the rear of the car.

Deputy Section Chief Zhang was also waiting for Li Aiguo to "fight back."

Seeing this, he was startled and quickly waved to the rescue team leader Liu Qingsong:

"Captain Liu, in order to ensure smooth railway transportation.

I now order you to immediately move these two carriages apart and repair the tracks urgently."

"But Driver Li, he..." Liu Qingsong was a little embarrassed.

Deputy Section Chief Zhang's face darkened: "Captain Liu, the cause of the accident has been investigated, and the car body is normal.

Even if it is transferred, it will not affect the investigation."

He was about to use the name of the investigation team to pressure Liu Qingsong, when Li Aiguo's voice came from a distance: "Everything is indeed normal on the car.

But sometimes, being too normal is a problem in itself.”

The sound was not loud, but it attracted everyone's attention.

Deputy Section Chief Zhang looked up and saw Li Aiguo squatting at the bottom of the car again.

"Driver Li, there is nothing wrong with the wagon. The problem is with the train driver, right? You can't ignore the facts just to protect your apprentice."

Deputy Section Chief Zhang felt that Li Aiguo was deliberately making trouble. "As a role model of our Qianmen Locomotive Depot, you have to do what a role model should do."

Li Aiguo ignored him and called Zhang and Chen, pointing at the brake pads under the car: "Lao Zhang, Lao Chen, what do you think?"

Engineer Zhang and Engineer Chen squatted beside Li Aiguo, looking at the huge brake shoe and frowned.

"Driver Li, the brake shoes seem to be in good condition."

Engineer Chen stood up and knocked the brake shoe with a hammer.
“Yes, it is in braking state now, you see, it is driven by compressed air.

The brake shoes hold the wheels very tightly, and they can travel at least 20,000 kilometers before they need to be repaired. "

The statements of Engineer Zhang and Engineer Chen seemed to confirm Deputy Section Chief Zhang's point of view.
Deputy Section Chief Zhang felt relieved immediately. He snorted coldly and said, "Driver Li, if you continue to make trouble, I will report your actions to the bureau."

Li Aiguo ignored him and continued, "Now let me ask you, did the train driver brake before or after the accident?"

"Isn't this simple? Why would the driver brake when there was no accident? The braking action must have occurred during..."

Mr. Chen didn't take it seriously at first and was about to blurt out.
But after thinking it over carefully, he swallowed back the words that were about to come out of his mouth, and stared at the brake shoe, unable to move his eyes away.

"Impossible, how is this possible?" Engineer Chen muttered to himself.

At this time, the flight attendants, train police, and even comrades from the Shanhaiguan Police Station also gathered around.

Although they didn't know exactly what was happening, they could feel that things seemed to be taking a turn for the better.

Zhou Huaiyi couldn't wait to ask: "Mr. Chen, what's going on? Please explain it clearly."

Mr. Chen was still immersed in extreme shock at this time and was speechless for a while.

Engineer Zhang was the first to react. He took a deep breath and pointed at the brake shoe and said, "Before the accident, the train driver could not have pulled down the emergency brake valve, which means the brake shoe could not have closed."

"After the accident, didn't driver Huang pull the emergency brake valve?" Zhou Huaiyi asked with a frown.

Engineer Zhang pointed to the connection between the car body and the carriage and said, "We just checked and found that the brake line connecting the front of the train and the carriage was broken in the accident.
Even if the train driver pulls down the emergency brake valve, the compressed air cannot reach the brake shoes through the brake pipes, and the brake shoes cannot press against the wheels to brake. "

Zhang Gong used a lot of professional terms in his explanation.
However, these people on the scene have worked on the railway for many years. Even if they are not maintenance workers, they all have common sense and understand the principles of train brakes.

They understood it instantly and excitement appeared on their faces.

"So, the cause of the accident was the sudden braking of the train?"

"Then this accident has nothing to do with driver Huang."

"Only an experienced driver like Driver Li can see it. If it were someone else, they would have moved the car body away by now."

Deputy Section Chief Zhang is the deputy section chief of the Safety Section.

At this moment, he understood the key point, and his face gradually became gloomy, like a dark cloud covering him, and gradually became darker.

What a good opportunity, is it just going to be wasted?
No. There is still a chance!

Deputy Section Chief Zhang rolled his eyes and said in a cold voice: "The brake line is indeed broken now.

But how can you be sure that the brake line was broken at the moment of the accident?

It was not that it was broken due to misalignment when the train overturned after the accident.

If it was broken after the accident, it would be normal for the brake shoe to close."

These words were extremely difficult to understand, and Deputy Section Chief Zhang blushed as he spoke.

After he finished speaking, he was still breathing heavily, and his fat body rose and fell violently with his breathing.

The onlookers heard his words, thought about them carefully, and the smiles on their faces froze instantly.

After all, the situation that Deputy Section Chief Zhang described is indeed possible.

In this way, it seems that the injustice against Driver Huang cannot be cleared.

Deputy Section Chief Zhang started to show off again, but this time he puffed out his chest and glanced at Li Aiguo sideways, like a proud rooster.

It’s just that this big rooster is too fat.

When the rooster is fat, it's time to slaughter it!
Li Aiguo looked at Deputy Section Chief Zhang and asked calmly, "Did you become the Deputy Section Chief of the Security Section through a backdoor?"

"what?!"

Deputy Section Chief Zhang was excited, but was shocked by these sudden words. For a moment, he even forgot to fight back immediately.

After waiting for him to react, he jumped up and pointed at Li Aiguo's nose and said, "Driver Li, you are going too far! You are slandering the leader."

"slander?"

Li Aiguo laughed twice, pointed to the connection between the car body and the carriage and asked: "The train pulls the following car with the help of the Zhan coupler. The Zhan coupler is made of high-strength and tensile-resistant alloy steel and can pull dozens of tons of cargo.

The brake lines are made of steel pipes and flexible hoses connected together with fittings.

The now strong James coupler was torn apart at the moment of the accident.

You actually stated that the brake line broke after the accident.

To come to this ridiculous conclusion, you must either be a fool or know nothing about train structure.

I don't think you are a fool, so you can only be the latter.

A person who knows nothing about train structure can actually become the deputy chief of the railway bureau’s safety department.

I suspect you took the back door, is that a problem?"

What is a lore shot?

That’s it!

At this point, Deputy Section Chief Zhang had to either admit that he was a fool or admit that he had used a backdoor.

No matter which one you choose, it will be extremely shameful.

This damn Li Aiguo, just because of my momentary negligence, he caught me with something and he still refused to let me go...

Deputy Section Chief Zhang smiled awkwardly but was speechless.

At this time, Deputy Head Ma of the investigation team realized that the situation was not good, and hurried out to smooth things over: "Head Wang's point of view is indeed problematic.

It is now certain that the train accident was caused by the sudden closing of the brake shoe and had nothing to do with the driver of the K16 train, Comrade Huang Jing. "The deputy leader of the investigation team, Ma, is an old man in his fifties, whose real name is Ma Dele.

He has a very good personality and smiles without even opening his mouth when he sees someone. This time he came to the bureau to work with Deputy Section Chief Zhang in order to prevent Deputy Section Chief Zhang from being too forceful.

But before coming, Deputy Section Chief Zhang had communicated with Ma Dele in advance that he would conduct a thorough investigation of the accident this time.

Ma Dele has worked in the General Administration for several years and has been in charge of security work, so he naturally knows what strictness means.

So when he arrived at the scene, Ma Dele remained as an "invisible man".

Even though he saw Deputy Section Chief Zhang confronting the K16 crew, he did not intervene.

But this time things were different.

Deputy Section Chief Zhang has now been completely defeated.

If he is allowed to act recklessly again, Ma Dele, the deputy team leader, will also be criticized when he returns.

As the deputy head of the investigation team, Ma Dele's opinion is equivalent to the result of the investigation team.

The onlookers all breathed a sigh of relief and cheers suddenly broke out at the scene.

Li Aiguo stared at Deputy Section Chief Zhang calmly: "Team Leader Zhang, since the accident has nothing to do with the train driver, shouldn't you let him go now?"

Deputy Section Chief Zhang had just been scolded, and now he was furious. He gritted his teeth and said, "Whether to release him or not, and when to release him, is a matter for our investigation team, not yours."

Ma Dele interrupted again: "Team Leader Zhang, Driver Li is right. Since we arrested the wrong person, we should release him immediately.

Besides, Driver Huang is the train driver on duty, she may know something, and having her here will also help with the accident investigation."

Several members of the investigation team also nodded and agreed with Deputy Team Leader Ma's opinion.

The railway system is a huge unit, so large that it has hundreds of thousands of people;
At the same time, it is a very small unit, and a maintenance worker can contact the director through five levels of interpersonal relationships.

It is an unwritten rule that it is best not to offend others easily unless you are absolutely sure that you can suppress them.

By arresting Huang Jing this time, the investigation team has taken a considerable risk.

Now that it has been found out that the matter has nothing to do with Huang Jing, they don't want to continue messing around with Deputy Section Chief Zhang.

When Deputy Section Chief Zhang saw that his subordinates had "betrayed" him, he almost fainted from anger.

There is also the old man Ma Dele, who usually has no presence in the Security Department.

He just raised his hand during the meeting, but at this critical moment, he dared to stab him in the back.

If there was time, Deputy Section Chief Zhang would definitely have a good talk with Ma Dele.

But now with so many people watching, he could only nod and agree.

"Let them go."

At this time, Huang Jing was chatting with the two comrades from Shanhaiguan Police Station in the carriage.

Huang Jing was startled when she saw Deputy Head Ma of the investigation team come in and stood up quickly.

The two police officers also stood up and stood in front of Huang Jing, saying, "Director Su has instructed that no one is allowed to interrogate Driver Huang without his company."

Deputy Team Leader Ma smiled and said, "Comrade, you misunderstood. Now the matter has been investigated clearly. The accident has nothing to do with driver Huang. We came here to inform you."

"Really?"

Huang Jing was surprised and happy, although she had always believed that she was innocent.

But I didn't expect that in just over an hour, I was cleared of suspicion. This was really incredible.

"It was driver Li who found the real cause of the accident."

Deputy Team Leader Ma gave a brief introduction to the situation.

Looking at Huang Jing, he smiled and said, "Driver Huang, it was indeed our mistake to arrest you this time.

But we are doing this for work, and we hope you can understand."

At this moment, Huang Jing was so happy as to have been reborn that she had no time to listen to anyone else. She turned around and quickly ran out of the rescue train.

It's sunny outside.

However, under the same bright sunshine, Engineers Chen and Zhang, as well as comrades from the accident investigation team, were squatting behind the carriage, all with frowns on their faces.

They smoked one cigarette after another, and cigarette butts were scattered all over the ground.

Li Aiguo walked around the carriage with his hands behind his back.

Huang Jing ran over quickly and was about to share her joy with Li Aiguo and the crew members, but when she saw this scene, she stopped immediately.

She saw Captain Zhou squatting there, so she approached him cautiously and asked in a low voice, "Captain, what happened?"

"Driver Huang is here. Congratulations on clearing your name." Time was urgent, so Captain Zhou did not bother to exchange pleasantries and just explained the current situation.

After determining that the train accident was caused by the sudden braking of the 14th carriage, the accident investigation fell into an embarrassing situation.

Because the car's braking system will not start automatically, if the train driver did not release the emergency brake in advance, then someone must have activated the manual brake at the back of the car.

However, the handbrake of the manual brake is only responsible for braking after parking, and does not consider the convenience of operation.

The handbrake disc is located at the rear of the car, close to the roof. It is impossible for anyone to apply the brakes while the train is moving.

Hand brake of an old freight car.

As a train driver, Huang Jing naturally knew the location of the handbrake disc and couldn't help but frowning.

Deputy Section Chief Zhang had also recovered from his earlier embarrassment.

Mr. Zhang and his colleagues looked confused and seemed to be racking their brains to no avail.

He suddenly perked up and said loudly, "Maybe it's a mechanical failure?

The train driver failed to detect the problem in time before driving, which led to the accident."

Engineer Zhang wanted to refute Deputy Section Chief Zhang, but he didn't have the confidence.

After all, they couldn't explain why the car suddenly braked.

If it were before liberation, some people would probably be wondering if the railway tracks had bad feng shui.

A female ghost in red emerged from the mass grave nearby, and it was said that the train accident was caused by the female ghost in red.

But the comrades who are able to work on the railways now are all firm fighters for materialism and naturally will not have such unreliable ideas.

The scene fell into silence.

Deputy Section Chief Zhang started to brag again, looked at Deputy Team Leader Ma and said, "If the train accident was caused by a defect.

According to the regulations, we should talk to the train manufacturer or the steam locomotive developers. "

When Deputy Team Leader Ma heard this, cold sweat began to appear on his forehead.

This old Zhang is getting bolder and bolder.

If it is really a train defect problem, it will involve the Railway Research Institute and Datong Locomotive Works.

Problems of this level are far beyond the scope of their bureau-level investigation team.

He did not respond to Deputy Section Chief Zhang. He pondered for a while and said, "Since we can't find the problem now, can we lift the car body first..."

Before he could finish his words, Deputy Team Leader Ma saw Li Aiguo suddenly turn around and walk towards the rear of the K16 train.

He quickly swallowed the rest of his words.

Engineer Zhang, Engineer Chen and the other flight attendants noticed Li Aiguo's actions.

Although they didn't know the reason, they all followed behind.

"Did this guy really find out the cause of the accident? How is this possible?"

Deputy Section Chief Zhang's face suddenly changed. He looked at the mass grave in the distance, hesitated for a moment, and followed.

When he reached the rear of the car and saw Li Aiguo stopped, Zhang Gong couldn't help but ask, "Driver Li, did you find anything?"

Li Aiguo pointed to the windshield at the rear of the train and said, "Do you think there is a possibility that the passengers in the 13th carriage climbed onto the train through the windshield and turned the handbrake disc?"

In those days, green carriages were the most advanced carriages, and there was an old-fashioned carriage called a "windshield coach".

The connection between the carriages of the "coach with windshield" is open.

There is an open platform connecting the two carriages, surrounded by protective iron railings.

There is a door in the middle of the front and rear of the bus body for passing through, and a foldable aisle steel plate is laid on the body coupler.

People can walk from one passenger car to the next car behind by stepping on the aisle steel plate at the connection (this type of passenger car was still in use in the 80s and 90s).

The windshield of the thirteenth carriage is located at the same end as the handbrake disc of the freight car.

In other words, as long as someone opens the car door and comes to the windshield, they can easily climb onto the car body and turn the handbrake disc.

Once the handbrake disc is twisted to the limit, the wheels of the following vehicle will suddenly lock, making a rollover accident very likely to occur.

Looking at the windshield, the expressions of everyone at the scene changed.

Deputy Section Chief Zhang's face turned pale at this moment, and he blurted out: "Impossible, who would do such a ridiculous thing.

Driver Li, you can't just find an excuse to shirk your responsibility."

The assistant driver of K16 responded: "Captain, this is not right.

As the old saying goes, if the forest is big, there will be all kinds of birds.

I placed my lunch box on the flower bed platform at the station the day before yesterday.

I took a look yesterday morning and saw that some bastard had peed in there."

"As for lunch boxes, you can just wash them and reuse them." Zhou Huaiyi said with a little sympathy.

The co-driver said darkly, "The point is that I thought it was beer."

Zhou Huaiyi: “.”

Li Aiguo: "."

Fifty-six people at the scene: "."

The co-driver of K16 came forward to share his experience.

At this time, Deputy Section Chief Zhang had no way to deny the possibility that someone was deliberately making trouble.

But he had another solution.

Deputy Section Chief Zhang looked at Li Aiguo and asked, "Driver Li, now that you have found the reason.

Then can we also catch the guy who did this?"

Li Aiguo put his hands behind his back and said with a smile: "Don't tell me, we have indeed found a suspect now."
