Siheyuan: Starting from a Truck Driver

Li Aiguo learned in the past few days that Lao Mao was the leader of the investigation team. His real identity, background and unit were not disclosed. The team of only four members was of a very high level. The fact that they participated in the rescue also included the investigation operation, which made Li Aiguo begin to speculate that the cave collapse might not be an accident.

As he thought about these questions, his nerves began to tense up. The content about physical discomfort suggested that he might need to go to the hospital for treatment, which might affect the release of the next chapter, the author joked.

Then, early in the morning of a new day, the rescue train left the Turpan Locomotive Depot in the soft morning light and traveled on the newly laid railway line.

All kinds of tools needed for building railways were scattered around. Wooden sleepers, steel sleepers, fasteners, line poles and anti-climbing devices, hammers, pickaxes, shovels and other objects were neatly arranged on both sides of the rails. In a wasteland not far away, camping tents were lined up. Just two nights ago, the Engineering Corps received an urgent instruction from the superiors.

In consideration of their hard work, the superiors arranged a day off for them so that the team could fully recover their energy. However, there was a condition - they had to clean up the debris on the tracks before the day off, and someone would inspect the results afterwards.

Railway soldiers rarely enjoy such a holiday. After breakfast, they plan to go to the county town 50 kilometers away to buy daily necessities such as toothbrushes and toothpaste. When the roar of the train sounded in the distance, they all came out with their bowls in hand to watch the excitement. The line has not been opened yet, so how can there be a train coming? Is this so-called rest to "make room" for it? Who are the people on the train?

The railway soldiers looked puzzled and doubtful. As the train entered the mountain road, the scene became more thought-provoking. The valley was rugged and the rails meandered between the peaks. In the past, hauling more than a dozen carriages was already a struggle, and the driver Li Aiguo had to shovel coal with his master Zheng.

However, at this moment, the locomotive only carried 7 carriages, and it was like a marathon runner who had taken off his weight, releasing his whole body and mind to gallop through the mountains. "Attention, there are signal lights ahead that have not been fully installed. We are about to enter the curve area." Quan retracted his gaze from the window and reported the information to the co-pilot cabin.

After hearing the report, Li Aiguo pulled the hand brake and the train slowed down. The construction progress in the curved area was not as smooth as before. After driving for a while, Li Aiguo noticed that the body of the train was shaking a little. It might be caused by the cracks caused by the welding connection and the loosening of the steel sleepers, which caused the position of the rails to change. If the inspection was carried out before the use, such problems would definitely be discovered and repaired in time.

Cao Wenshu, who was supposed to go to change shifts, had doubts in his heart. He came to the cab and asked with concern: "Is there anything wrong with Aiguo?" Li Aiguo replied: "I don't think it's a big problem. The shaking is still within the tolerance range of the car body."

As soon as he finished speaking, there was a loud noise - the train shook violently and tilted sideways. Cao Wenshu didn't have time to think about it, and his head hit the window hard. Fortunately, he reacted quickly and quickly shrank his body to avoid this head-on competition with the glass.

Experienced driver Cao Wenshu understood that the violent vibration was caused by a loose screw falling off when the wheel was running at high speed, causing part of the rail to shift. The originally smooth and straight rail suddenly bulged out, and the high-speed wheels hit the bulge, causing the entire train to tremble violently. Cao Wenshu squatted on the ground, his face pale, and beads of sweat rolled down his forehead.

As the shaking became more and more severe, the train gradually approached its limit - the edge of derailment. If it derailed during the rush, the driver's cab would be crushed even on the ground, not to mention that at this moment, it was on the mountainside, surrounded by jagged rocks on both sides.

Liu Qingquan and Master Zheng looked ashen, with fear in their eyes. In the cab, except for Li Aiguo and Lao Mao, no one else could remain calm.

Stopping fiddling with the radio, the old cat let out a long sigh, then turned to look at the stove. The firelight reflected in his pupils, as if a bright red faith was leaping in them.

Li Aiguo's expression did not change at all. He analyzed the danger point amid the violent jolt and the whistle of the train - two centimeters, just two centimeters of track height difference. The bulge of the track appeared.

At this time, the train had turned right, and the danger of the right wheel hanging in the air was even more imminent. In order to save it, he shouted: "Old Zheng, burn it!" "Provide power at all costs!"

This roar made everyone in the cab suddenly wake up, and they rushed to the boiler. Lao Zheng suddenly opened the furnace cover, waved the big iron shovel, and added coal frantically without any scruples. Quan jumped out of his seat, picked up the spare shovel to help, and Cao Wenzhi and Lao Mao followed closely behind, even without a spoon to shovel the coal, they just picked it up with their bare hands.

Although they did not understand the purpose of this action, facing the critical moment of life and death, if they did not take action, they would be sitting and waiting for death. Buckets of coal were added to the stove, and the raging fire climbed to an unprecedented height, black smoke filled the air, and the speedometer suddenly increased.

The front of the car tilted more and more, and the huge rocks on both sides could be touched by sticking out the window. The hideous lines seemed to be within reach. "No, it's not fast enough, it needs to be faster!" Li Aiguo's eyes were fixed on the speedometer, and his fingers were firmly gripping the front and rear brake valves.

Cao Wenzhi was stunned. The train was traveling at nearly 80 kilometers per hour. Braking suddenly at such a high speed could easily cause the train to derail due to the force of the carriages. They knew that any stopping action would be fatal under heavy loads.

Did Li Aiguo really overlook this? Just as Cao Wenzhi was about to question him, the train shook even more violently, and Quan lost control and was thrown to the side, hitting his head on the boiler, with blood dripping down.

Cao Wenzhi gave a helpless smile. Anyway, the train was already on the verge of losing control. What would happen if it derailed again?

In an instant, his thoughts turned, and he picked up the coal shovel from Liu Qingquan's hand and stuffed coal into the furnace regardless of everything.

"Ninety plus, already over a hundred."

Li Aiguo accurately estimated the train's speed, load, roll angle and the degree to which the wheels were off-center, and slammed the brake valve at the front of the train.

The brake air duct quickly transfers compressed air to each auxiliary air cylinder, applying pressure to the brake shoes, forcing the brake wheels of the carriage to slow down. The friction between the rails and the wheels is intense, sparks fly, and the roar is piercing.

The speeding car following behind was driven by inertia and slammed into the front of the car in front.

After the violent impact, the carriage actually began to tilt upwards.

Can you stop just by braking?

This could not prevent the train from overturning, and Cao Wenzhi had just put his mind at ease.

Suddenly, Li Aiguo released the brakes at the front of the train and opened the door of the carriage.

The air supply braking force of the car body and head is different, it relies on exhaust braking.

The huge gate quickly releases the pressure, and the reset push rod in the auxiliary air cylinder acts on the brake shoe, causing it to tightly clamp the wheel.

At this moment, Li Aiguo pulled the brake valve on the front of the car again.

The violent deceleration of the carriage just after landing had a noticeable effect, and the front of the train slid slightly due to the traction.

Due to inconsistent braking force, the train's tilt angle actually decreased.

Just like a rope, it will deviate from its original equilibrium state under the action of double forces.

Could it be that Li Aiguo was trying to get the entire train back on track by controlling the braking force distribution between the locomotive and the carriages? Cao Wenzhi was so shocked that he couldn't help but gasp.

As an old boilerman with a million kilometers of driving mileage, he knew all these possibilities, but he had never imagined using them in this way.

The timing is very precise and difficult. If there is a slight mistake, the whole car will be difficult to control and the people and the car may be destroyed.

Therefore, it is clearly emphasized in the driving manual that drivers are strictly prohibited from using the main brake and the auxiliary brake alternately.

However, Li Aiguo actually adopted an illegal method to try to reverse this dangerous situation.

Realizing this, Cao Wenzhi immediately tried his best to move coal and fill it into the furnace.

Liu Qingquan, Master Zheng and Laomao were not clear about the operating principle of Li Aiguo, but they clearly felt that the inclination of the car had eased a lot.

Seeing hope, they shoveled coal with greater force, trying to give the train extra power as much as possible to help Li Aiguo share the pressure.

With Li Aiguo's precise operations again and again, the train's tendency to overturn gradually improved.

...The rabbit fell to the ground because he missed a watermelon.

It’s not suitable to eat watermelon on rainy days, so take this as a warning!

I am exhausted today.

I have to go to the hospital for an IV drip later.

This chapter ends.

Wait a moment.

Surrounded by mountains,

A train was running on the rugged and narrow railway tracks, emitting black smoke intermittently.

The roar of the train disturbed the tranquility of the valley.

Birds spread their wings and soar into the sky.

The lumberjacks at Daxing Forestry Station were just about to start work when they were suddenly attracted by the sounds coming one after another and turned their heads to look over there.

The car body was tilted, sparks flew from the friction between the wheels and the rails, and it seemed like it was about to crash into the steep cliffs next to it.

Everyone was shocked by the scene before them.

The calloused hands loosened the axe they were holding, and it fell to the stone ground with a clang.

“Why isn’t the road open yet?”

"Nonsense! What is this for!"

“It’s going to flip over!”

"There's a phone here. Call our brothers on the railway and inform them. The medical staff at the hospital must also come as soon as possible."

"Get ready, everyone, take the ropes, we are going down to rescue people."

"We'll do our best and save as many people as possible."

The leader of the logging team was a strong man who gave orders quickly and everyone took action immediately, picking up their equipment and preparing to slide down the steep slope to rescue.

At this moment, another scream rang out.

"Team Leader Liao, calm down. It seems like the train is back on track."

"What? How is this possible!"

The captain looked up, his mouth open in disbelief.

The train was like a living machine. Knowing the danger of derailment, it gradually returned to its original position.

"how so……"

His voice trembled, and the rope he was holding tightly sagged. The rope tied around his waist fell quietly into the valley, making a rustling sound.

Inside the car,
