The train is still in the curve, but it is constantly accelerating, and this time the speed increase is significantly faster than the previous three times. Pen, fun, and www.biquge.info

On the last section of the easing curve, everyone clearly felt that with the increase in speed, the vibration and swaying of the car body increased violently, and the sound of clanging was louder, making people feel that the car was about to roll over in the next moment.

Chu Jianghe grabbed the table with both hands, his face was as usual, his eyes jumped, and he felt the impact of the train during the journey.

Everyone in the carriage grabbed something fixed and said nothing.

"The speed is 110 km/h, and it immediately enters the straight line. Inside the walkie-talkie, the voice of the person in charge of the front of the car came again.

Hearing this, everyone's tense nerves finally breathed a sigh of relief, once the curved section passed, running 120km/h in a straight line, everyone was still acceptable.

"The speed is 111 km/h, and it enters the straight section area, and the length of the straight section ahead is twelve kilometers. At this time, the voice came from the walkie-talkie again.

When he heard that he had entered the straight section, Chu Jianghe also relaxed, in fact, the distance traveled by the train, he had been silently thinking in his heart, and he calculated the part of the curve where the train traveled according to the time and length of the curve when the train entered the curve.

The reason why Zhao Zongrong was allowed to accelerate just now was mainly because Chu Jianghe judged that there would be no big problem if he accelerated on this curve according to the driving situation of the first half of the curve, and he just suggested that Zhao Zongrong accelerate so resolutely.

Unexpectedly, Zhao Zongrong finally acquiesced to his words and asked the train driver to drive at full speed and move forward at great speed!

At this moment, although the train is still accelerating, everyone's spirit is not as nervous as just now.

"It's passed!" At the moment when the train passed the curve, Li Duanchang said excitedly.

"Although this is a bold approach, it has made us realize that we can run 110 km/h on curved sections, and now it seems that running 120 km/h on curved sections should not be a problem. Sun Duanzi of the train service section also spoke.

Zhao Zongrong glanced at Chu Jianghe, showing a faint smile, for what Chu Jianghe just said, Zhao Zongrong didn't know the bottom in his heart, but he felt that Chu Jianghe was full of confidence, so he did it, but he didn't expect it to be really successful.

"Jianghe, the train will immediately speed up to 120km/h, will the next step be to keep driving at a constant speed, or continue to accelerate?" asked Li Duanchang about the Chujiang River.

After Chu Jianghe's two suggestions just now, everyone found that according to Chu Jianghe's words, the train was not only safe and sound, but also exceeded the expected speed.

As soon as Li Duan asked, everyone present looked at Chu Jianghe, even Zhang Haipeng did not stand up to speak, but waited for Chu Jianghe to speak.

In the carriage, a strange phenomenon occurred, the upper leaders of the Shenzhen Branch of the Chutan Railway Bureau, as experts in the railway system, actually asked for the opinion of a 'layman'.

Obviously, in everyone's hearts, they have realized that the reason why Chu Jianghe dared to let Zhao Zongrong speed up must have his reasons, but he didn't say it.

Looking at everyone's expectant expressions, Chu Jianghe smiled slightly and said, "Leaders, how do I know this, you are all railway experts, and what speed the train will run next, but Zhao Ju has the final say." ”

"Get out, you kid give me an honest face, give you a chance to be a leader today, you say speed up, you say keep 120km/h, just keep this speed!" Zhao Zongrong glared at the corner of his mouth with a smile, and the atmosphere was harmonious.

As soon as these words came out, everyone around looked at Chu Jianghe with strange eyes, Zhao Zongrong's words looked like a joke, but everyone didn't take this as a joke, because the speed of driving is related to many aspects, and there may even be accidents!

Zhao Zongrong actually believed in Chu Jianghe so much, there must be his reasons, or rather, Zhao Zongrong had confidence in Chu Jianghe, otherwise, he would not have listened to Chu Jianghe's advice several times just now to increase the speed.

Looking at everyone's expectant eyes, Chu Jianghe said solemnly: "Zhao Ju, if you believe me, increase the speed to 130km/h, I'm afraid that the traction will not work!"

For the Dongfeng 4B diesel locomotive, let this freight train, run to 130km/h, has used up ninety percent of the horsepower, although full horsepower, can make the speed of the train increase again, but the room for improvement is also limited, plus Chu Jianghe to the Dongfeng 4B internal combustion engine full horsepower traction, in the end there will be any drawbacks do not understand, so it is conservatively recommended to increase the speed to 130Km/h.

Before the big speed, like this kind of diesel locomotive, can play eighty percent of the horsepower, it is very good, plus the Ministry of Railways is very strict in speed control, the railway speed has not been put on the agenda, so that the speed of the train, has been below 120km/h, several major trunk lines, and even perennial maintenance at 50Km/h-70km/h.

Another factor is because of the rails, now the line of the deep city section is only replaced with wooden sleepers, replaced with concrete sleepers and elastic fasteners, 50 rails have not been replaced with 60 rails, due to the problem of supporting rails and sleepers, it also has a certain impact on the running of the train.

Therefore, Chu Jianghe did not recommend a higher speed.

As soon as Chu Jianghe said, Zhao Zongrong nodded slightly, and hurriedly sent out an order for people to pass it to the driver who drove the train.

Soon, the speed increased to 120km/h, and the speed of the train was still improving, compared to the speed of 120km/h, the speed of the train increased again, which did not make everyone in the carriage feel any discomfort.

"The train is traveling at 130km/h, and there are still eight kilometers ahead, entering the curve!" said again from the intercom.

"Good!"

Hearing this voice, Zhao Zongrong roared and said excitedly.

The speed of 130km/h, although it is not the first train in China, provides a solid foundation for the completion of electrification and whether the speed can reach 160km/h.

You know, the first big speed, the highest speed in China, is only 140km/h, and it is a passenger train, that was in 97 years, if it were not for the country at that time in order to stimulate domestic demand, as well as the needs of all aspects, the railway speed, I am afraid it will have to retreat.

The things that Zhao Zongrong is doing now are equivalent to speeding up the domestic railway, which is a full eleven years ahead of schedule!

This is definitely a great credit, even if the transformation is completed, the maximum speed of the train can not reach 160km/h, but it is only increased to 150km/h, and the average speed is maintained at 120km/h.

"Zhao Ju, slow down, the front is about to enter the curve area, I suggest reducing the speed to 80km/h. Facing the excited Zhao Zongrong, Chu Jianghe suggested.

The reason why it is recommended to reduce the speed to 80Km/h is mainly because, the radius of the curve in front is only 600m, the speed is too high, Chu Jianghe is worried about problems, and moreover, after this curve, the longest straight section, the longest is only a few kilometers, and there is no condition to run 120km/h again, rather than this, it is better to reduce the speed, after all, the maximum speed of the train has reached 130km/h.

"Okay, start to reduce the speed now, try to control the speed within 80km/h before entering the next curve, and then slowly decrease!" Facing Chu Jianghe's words, Zhao Zongrong did not hesitate at all, and issued an order.

Because the maximum speed has reached 130km/h, the goal has been achieved, and it doesn't matter how fast you run next, not to mention that you are about to enter the Chutan area, and the speed of driving will drop when the time comes.

Soon, the train traveled rapidly, passing through the Shentan Railway Shenshi area, and when entering the Chutan area, the speed had dropped to less than 50Km/h, compared with the speed of the Shencheng section, the train was significantly reduced.

Now that everyone looks at the speed of the train, they can't help but feel that the car is moving like a snail.

"Zhao Ju, it seems that the use of concrete sleepers and elastic bar fasteners has a great effect on the speed of the train. Li Duanchang sighed.

After this trial operation, everyone can be said to have experienced it firsthand, the train is passing through the concrete sleeper area and the wooden sleeper area, and the speed is completely one heaven and one earth.

"Yes, I am now eager to complete the electrification transformation as soon as possible, so that my old bones can also feel the speed of 160km/h, and now in China, except for airplanes, there should be no such fast cars, right?" Zhao Zongrong smiled.

At this moment, he felt more and more that it was a wise choice to adopt Chu Jianghe's opinion at that time to replace the sleepers of the Shentan Railway with new concrete sleepers and elastic bar fasteners.

Once this experiment is successful, it will play a vital role in Zhao Zongrong's future career.

"Probably not, the fastest car I have ever felt 100km/h, it is already very fast, I feel like I have to fly. Sun Duanzi shook his head and said.

"No, it seems that the train is safe. Li Duan said.

Everyone, you and I said a word, and the conversation was very pleasant, because the train had entered the Chutan area, there was no trial operation, and they were all running at a normal speed, and everyone no longer paid attention to the speed of the train.

During the conversation, everyone obviously attached a lot of importance to Chu Jianghe's words, and many people even suspected that Chu Jianghe was a railway expert specially invited by Zhao Zongrong!

"Mr. Zhang, after arriving in Chutan City, we must get the data of the train out and study it carefully, although the maximum speed has entered 130km/h, we can not be proud, because this is just the beginning, there is a longer road in the future, we need to explore step by step. Based on this experience and data, we should find out the factors that affect the speed of the train, and then reduce the impact of these factors on the train as much as possible, and finally achieve the safety of the train operation. After all, the safety of the train affects the lives of thousands of families, and there must be no sloppiness!" Zhao Zongrong looked at Zhang Haipeng and said solemnly.

"Yes, Zhao Ju!" Zhang Haipeng said with a serious face.

Zhang Haipeng just stood up to refute Chu Jianghe, Li Duanchang and others, also from the perspective of security, after all, he is the person in charge of technology, and he seriously disapproves of Chu Jianghe's casual words. After driving, there is no major problem with safety, and Zhang Haipeng has no reason to refute, but chooses to learn and summarize with an open mind!

The train traveled slowly, and finally, the train entered the No. 1 platform of Chutan Station, at this time, on the platform, Huang Changan, director of the Chutan Railway Bureau, and others actually stood on the platform to greet everyone!
