Seeing Liu Feng in middle age again, Chu Jianghe found that compared with the high-ranking and powerful Liu Feng in his previous life, Liu Feng at this time seemed very introverted and not so arrogant, perhaps because of his position or experience. Pen ~ fun ~ pavilion www.biquge.info

Even now Liu Feng himself can't believe that in the next ten years, he will reach the highest level of the Ministry of Railways, and he will be able to guide the railway system and display his ambitions!

As soon as Chu Jianghe and Liu Feng met, they chatted about speculation, in fact, Chu Jianghe did it intentionally, after all, Liu Feng was also an acquaintance he saw after he was reborn.

"Jiang He, in your opinion, if the speed of this trial operation enters 160km/h, can this speed be promoted in all aspects in China?" The two followed behind the large army, Liu Feng asked unhurriedly, looking very cordial.

"Bureau Liu, what do you think?" Chu Jianghe was stunned for a moment, and did not answer immediately, but asked with a smile.

"To be honest, I don't know much about railway design and research, and I don't have much right to speak, in my opinion, since you can produce a patent for a new type of concrete sleeper and elastic bar fastener, you are obviously more familiar with the railway than me. Liu Feng said without hesitation.

In fact, this is also the case, Liu Feng doesn't understand anything about professional knowledge in railways, he doesn't even care about these things, when he came to power as the boss of the Ministry of Railways, what he showed was not how strong his technical ability was, but courage, indomitable courage.

For example, he asked that a railway with a speed of 160km/h must be built within two years, Liu Feng will not care what difficulties exist in your design and construction, how many difficulties there are, he only gives this order, where it does not work, he will throw money, this is Liu Feng's style.

It is precisely because of this courage that China has embarked on the generation of high-speed rail.

Chu Jianghe nodded slightly, and said: "To be honest, in my opinion, the trial operation of the Shentan Railway breaks the speed of 160km/h, the problem is not big, the key is whether this speed can be maintained, after all, the roadbed and bridge foundation of the Shentan Railway are relatively weak, not to mention that it is impossible to use 160km/h for a long time, even if the running speed of 120km/h is used for a long time, it is quite difficult." As for the national promotion, I think it is not yet time, how to deal with the roadbed, how to prevent the settlement of bridges and other problems, have not been solved, just like the national promotion of 160km/h, it is difficult. ”

"Yes, the foundation is not strong, this is the fatal wound of high-speed rail. Liu Feng nodded.

As for the design basis of the Shentan Railway, he obviously understands that before the electrification transformation, the average speed of operation was less than 45km/h, and after the transformation, it is quite difficult to enter the average speed of 120km/h.

Whether it is a bridge or a roadbed, in the face of doubling the operating speed, it cannot withstand the long-term dynamic load impact during the operation of the train.

The two walked and chatted and came to the third floor of the Chutan Railway Bureau, where there is a large conference room, the conference table is placed in the middle of the rectangle, except for the side of the door, the other three sides are placed two rows of stools, dozens of seats, even so, because there are too many people participating in the trial operation, Chu Jianghe and Liu Feng can only stand in the back, and the stools are not enough at all.

The content of the meeting is quite simple, that is, to arrange the matters of the trial operation, and at the same time explain the safety and itinerary arrangements of the trial operation.

The meeting lasted for about half an hour, and at 9:15, everyone had already arrived on the platform of Chutan Railway Station.

At this time, on platform 1, a passenger train was parked, which was full of twelve green leather cars, which was a standard passenger train in 86.

The locomotive is still Dongfeng, but it has been replaced by an electric locomotive, and it is no longer a diesel locomotive.

Outside each carriage, the conductor stood neatly and waited for everyone to board the train, and the conductor waited at the second carriage.

Under the leadership of the service staff at Chutan Station, Minister Luo and others walked into the No. 2 carriage, a total of 16 leaders were arranged in the No. 2 carriage, and the other members were arranged in the No. 1 and No. 3 carriages respectively.

Chu Jianghe and Liu Feng were arranged in the No. 3 car, and in this car, most of them were the deputy directors of the external bureaus and railway employees who came to learn from their experience, as well as some members of the Chutan municipal government, as many as 40 people.

"Jianghe, let's sit here. After getting in the car, Liu Feng said to the Chu River.

The green hard sitting of the same color made Chu Jianghe feel familiar and unfamiliar, Liu Feng sat by the window, Chu Jianghe was in the aisle, because there were enough seats, no one else sat down on the opposite side, and everyone sat relatively scattered.

In order to entertain these people, the Chutan Bureau specially arranged for Wang Quanning, deputy director of the bureau, and Zhang Biao, director of a chief engineer's office, to hold walkie-talkies in their hands to explain to everyone.

At 9:30, the train officially began to run, departing from Chutan Station.

As the train moved, everyone stopped talking and felt the feeling brought by the running of the train, and the train was obviously speeding up when the train left the signal light at the far end of Chutan Station.

"Leaders and colleagues, the train has now left Chutan Station, and I will give you a brief introduction to the entire operation process. At this time, I saw Zhang Biao stand up, stand in the middle of the carriage, and speak.

Everyone withdrew their gaze from the window and looked at him.

"The trial operation, in terms of speed, will be divided into four parts, out of Chutan station, the running speed of the train, will accelerate to 60km/h, at this speed after running for three minutes, after adjusting the operating parameters of the train, will accelerate again, directly into 100km/h, after reaching this speed, the train will maintain this speed at a constant speed, until entering the longest straight section of the Shentan Railway, the train will begin to accelerate in the second half of the gentle curve section, will be in this straight section, challenge 160km/ When there are still three kilometers away from the straight section, the train will begin to slow down, keeping the running speed not less than 100km/h, and entering the deep pool section to start, the speed will run between 100km/h and 140km/h, even if it is a curved section, the running speed will not be less than 100km/h. Zhang Biao explained.

Hearing Zhang Biao's explanation, many people in the carriage showed a hint of surprise.

Although I have long heard that the trial operation will challenge the driving speed of 160km/h, it can be affirmed by Zhang Xing, which is inevitably a little surprising, after all, in China, so far, the running speed of the railway has not exceeded the 160km/h hurdle.

Once the breakthrough is made, it will undoubtedly be a milestone for the domestic railway.

In addition to the top speed that surprised everyone, Zhang Biao also had a sentence that also surprised everyone present.

That is the whole running speed, not less than 100km/h, this speed in 1986, is already very high, you know, in the three major trunk lines in China, the average speed is only 85km/h, which is equivalent to the trial operation, not only to break the highest running speed, even the highest average speed of the whole process, will also be broken.

Liu Feng glanced at Chu Jianghe, frowned slightly, and said, "Jianghe, do you think this railway can reach the speed he said?"

"Trial operation shouldn't be a problem. Chu Jianghe thought about it and said so.

Chu Jianghe did not say that it could continue to be maintained during the official operation, but that the trial operation could be achieved, after all, the errors and indicators of the Shentan Railway were the best in this trial operation, and in this case, it was completely possible to run one or two trips at this speed.

Once you maintain this speed for a long time, it is impossible.

Liu Feng was slightly stunned, nodded and said, "This is about the same, otherwise this line will be against the sky!"

Obviously, Liu Feng understood the meaning of Chu Jianghe's words.

Soon, the train accelerated to 60km/h, a speed that was no lower in 1986, and the trees on both sides of the carriage were rapidly retreating, indicating that the train was running fast.

About three minutes later, Chu Jianghe felt that the carriage was being pulled vigorously, and he knew that the train was about to speed up again.

As for the first three minutes, it is to allow the train to adapt to this speed.

"The next train is to accelerate to 100 km/h. Zhang Biao's voice came again.

Chu Jianghe found that Liu Feng grabbed the table in front of the chair with both hands, looked out the window, and felt the train accelerating.

At the same time, Chu Jianghe is also feeling the acceleration of the train, because in last month's trial operation, Chu Jianghe has tried once, knowing the basic situation of the line, as the train accelerates into the curved section, Chu Jianghe found that the swaying and vibration of the carriage is obviously not as violent as the last 100km/h, and even passed very gently.

Obviously, the use of 60 rails, coupled with the later adjustment of the line elevation and gauge, the line is more and more suitable for high-speed driving.

"Yes, it is indeed faster than the speed of our Zhengzhou Railway Bureau, and it is more stable!" Liu Feng suddenly sighed after nearly half of the curve.

"Bureau Liu, what do you say?" asked Chu Jianghe.

"In the Zhengzhou Road Bureau, there are also several passenger train speeds, tried the average speed of 100km/h, but they are all in a straight line, for the curved section, most of them are 70km/h, but even if it is 70km/h, its stability, in my opinion, is not as stable as the 100km/h operation of this train. Liu Feng said and continued: "Every time I pass through the curved section, the carriage swings quite seriously, and the vibration of the car body is relatively strong, but this trial operation, I paid special attention to this aspect of the problem, and found that this aspect of the situation is not serious." ”

Zhengzhou Railway Bureau and Chutan Railway Bureau have the same status, which is also the overall situation, plus several trunk lines pass through Wuhan, so in terms of running speed, it is relatively fast.

For Liu Feng, he can be regarded as having seen the world, but in the face of the trial operation of the Shentan Railway, he still lamented that the Zhengzhou Railway is not as good as this side in terms of running speed and the condition of the line.

"Maybe it's because the 60 rails fit in with the concrete sleepers and snap bar fasteners. Chu Jianghe said casually.

"I think so, and it's very likely. Liu Feng nodded.

When the train maintained a constant speed of 100km/h, Zhang Biao began to speak again, but Chu Jianghe didn't listen at all, he kept feeling some problems in the operation of the train.

"It's about to sprint to a speed of 160km/h below!" Zhang Biao said suddenly.

When everyone heard this, they only felt that the car body was pulled by a huge force, the train was accelerating, and everyone in the carriage obviously felt that the speed of the car was getting faster and faster.

Liu Feng grabbed the table with both hands and looked out the window, his face full of excitement.

"The speed of the car is already 150km/h!" Zhang Biao looked at a speedometer in his hand and said excitedly.

Obviously, if we continue to accelerate, we will break through 160km/h, even if we don't break through 160km/h, this trial operation has also broken the highest speed record in China!

“155km/h！”

“158km/h!“ Zhang Biao looked at the speedometer and shouted excitedly.

"160km/h!, success!"

呲呲呲~~~

At the moment when Zhang Biao called out successfully, the train suddenly braked, and Chu Jianghe felt like someone was pushing him behind his back, and his body fell forward quickly!

In the carriage, everyone was crooked and chaotic!
