Everyone was puzzled when they saw Zhao Zongrong bringing Chu Jianghe in, because several of these leaders knew Chu Jianghe and knew that he was the boss of a construction team. Pen % fun % Pavilion www.biquge.info

Although this trial operation is not official, after all, the electrification transformation has not yet been completed, and only the internal combustion engine can be used for traction, but even so, under normal circumstances, only people from railway units can participate, and outsiders are not qualified at all.

Zhao Zongrong didn't explain, and the others didn't ask, obviously, since Zhao Zongrong brought Chu Jianghe to participate in this trial operation, he must have his reasons.

Zhao Zongrong introduced some of the members present to Chu Jianghe, and the lowest was also at the department level, with more than a dozen people.

Among these members, there are the heads of the chief engineer's office, office, safety supervision office, railway transportation department, vehicle department, public works office, electrical affairs office, locomotive maintenance office and other departments of the Shenzhen Branch.

After being introduced, Chu Jianghe knew that Zhao Zongrong's purpose for bringing him here was to make an exception for himself to participate in the trial operation of the railway.

After knowing this result, Chu Jianghe was still a little surprised, in his previous life, Chu Jianghe did participate in the trial operation of the railway unit, but it was during the construction of the high-speed railway, and he participated as the chief designer of the design institute, and the treatment was equivalent to that of the director of the road bureau.

Now his identity is just a construction team owner, plus the identity of two patent owners, he can actually participate in the trial operation of the railway unit.

However, thinking that the electrification transformation has not yet been completed, although this operation is a trial operation, it is not formal at all, perhaps it is precisely because of this that Zhao Zongrong dared to make an exception, after all, among the leaders present, he held the highest position, and even Huang Changan, director of the Chutan Railway Bureau, did not participate.

At 9:15, under the leadership of the person in charge of the station, everyone passed through the VIP channel and went directly to the platform, at this moment, on the No. 1 platform, a freight train was parked, and on the platform, there were some service personnel at the station.

This freight train is not the same as the ordinary, first of all, the traction of the carriage is not an ordinary freight train captain, in the impression of Chu Jianghe, before the transformation of the Shentan Railway, the railway freight train pulled up to 50 carriages, which is already very good, not that the line is not good, but the traction power is affected, implicated in the lack of power, which directly affects the number of traction carriages.

In addition, even if the train can be pulled and pulled, the speed cannot keep up, which is also a problem, because there is a limit on the speed of the train on the railway, and it is impossible for only one train to pass on a line in one day, and if the speed is too slow, it is likely to affect the running of the next train.

Secondly, Chu Jianghe found that the front of this freight train is not the same, the general freight train, only the locomotive, followed by all the freight carriages, and the platform parked in addition to the diesel locomotive, there is also a green leather car, which is obviously specially used to sit people, specially added.

The most surprising thing for Chu Jianghe was the locomotive, only to see the front of the locomotive, written Dongfeng 4B, laymen are not familiar with the nose of this model, but Chu Jianghe is very clear.

Since 1958, China has manufactured diesel locomotives, and three types of locomotives such as Dongfeng type have been put into mass production at the earliest, and after 1969, 15 new models such as Dongfeng 4 have been mass-produced.

Compared with the first generation of diesel locomotives, there are significant improvements in power, structure, diesel engine thermal power and transmission efficiency.

In Chujianghe's memory, the speed of the Dongfeng 11 passenger locomotive has reached 160km/h, but this is already close to 2000.

In the next ten years, the carriages mainly used to pull passenger and freight trains on the main railway line include Dongfeng 4B, Dongfeng 4D, and Dongfeng 11!

The emergence of Dongfeng 4B locomotive means that the speed of China's railway has entered a new level, which is also equivalent to a turning point in the speed of domestic railway operation!

Dongfeng 4B internal combustion engine, used in the passenger car production year in 1973-1975, truck in 1969-1986, from the appearance and structure of the front of the car, this head, obviously just produced, all aspects of performance, in the country is the best.

Dongfeng 4B internal combustion engine, the maximum application probability of diesel engine is 2430kw, the speed of traction trucks can reach 100km/h, and the running speed of passenger cars can reach 120km/h.

Obviously, Zhao Zongrong put this new nose here, or he wanted to challenge the speed of 120km/h, otherwise, he would not have halved the truck compartment.

There is only one purpose, to reduce the load on the internal combustion engine and increase the speed of the train.

"Dongfeng 4B internal combustion engine!" Chu Jianghe looked at the nose and said.

"Is Jiang He familiar with this aspect as well?" Zhao Zongrong asked casually on the side.

"I'm not familiar with it, but when I take the train, I often encounter the locomotive that starts with the east wind, and I'm just curious. Chu Jianghe said with a smile.

Now is not the time to pretend to be B, once the head is the way, people still doubt themselves, after all, in the eyes of the people present, Chu Jianghe is just a person outside the system, even if it is a person inside the system, not the leader in charge of this part, and he does not know much about the internal combustion engine model.

Under the arrangement of the station staff, Chu Jianghe followed everyone to the carriage behind the front of the car, inside the carriage, Chu Jianghe's familiar green wagon, and the windows could also be opened.

For this trial operation, the Shenzhen City Operations Department specially arranged a deputy department to contact another person in charge of the green car in front of the front of the car, what ideas and instructions Zhao Zongrong has, directly through the walkie-talkie, contact the members in front, and let the train driver respond.

Today's diesel locomotives are not like electric locomotives, and the running speed of electric locomotives is completely adjusted by the station, and even the acceleration and deceleration can be controlled by the station. But diesel locomotives are different because diesel locomotives use diesel fuel and need a train driver to control the speed of the train.

"Jianghe, you sit here. After getting on the train, because Zhao Zongrong was in the first carriage, he found a window position in the middle of the left side, and after sitting down, he pointed to the seat next to him and looked at the Chujiang River who was queuing up to get on the bus behind.

A leader of the Shenzhen City Branch, who was originally going to sit beside Zhao Zongrong, stopped and sat down opposite Zhao Zongrong.

Everyone in the carriage, when Zhao Zongrong finished speaking, almost all looked at Chu Jianghe, revealing doubts.

When Zhao Zongrong took Chu Jianghe into the VIP passage just now, although Zhao Zongrong introduced Chu Jianghe to everyone, everyone didn't care, thinking that Chu Jianghe came to visit and study through Zhao Zongrong's relationship, after all, Chu Jianghe's age was there.

The members in the carriage, except for Chu Jianghe, the youngest are also over thirty-two years old, and they are still a minority, most of them are over forty, and a few are still in their fifties.

From Zhao Zongrong's words, the talents in the carriage realized that Chu Jianghe's identity today was not ordinary, and a few people who knew that Chu Jianghe was the leader of the construction team couldn't help but look at Chu Jianghe twice, not knowing what they were thinking.

Facing everyone's attention, Chu Jianghe smiled slightly, and in a passage that everyone got out of, he came directly to the seat beside Zhao Zongrong and sat down.

At the same time, the other leaders of the Shenzhen Branch also found a seat and sat down, and everyone started talking from time to time, and Chu Jianghe kept listening.

At 9:25, Chu Jianghe heard the message from the walkie-talkie, the train was about to start, and at the same time, the door of the carriage was also closed at this moment.

"You can all guess how fast the train can reach in this trial operation, and explain the reasons. At this moment, Zhao Zongrong suddenly spoke.

Hearing Zhao Zongrong say this, everyone seemed very interested, because this problem, when they knew about today's trial operation, it was circulated within the Road Bureau, speculation, and different opinions.

"At least 80km/h!" said an elderly man across from Zhao Zongrong.

In the introduction just now, Chu Jianghe knew that the other party was the leader of the chief engineer's office, named Zhang Haipeng, and he originally wanted to sit next to Zhao Zongrong just now, but finally gave up his seat to Chu Jianghe because of Zhao Zongrong's words.

After Zhang Haipeng finished speaking, he continued: "Although the internal combustion model has been replaced with Dongfeng 4B, the traction power is enough, but after all, half of the freight carriage is still pulled, and the carriage is still loaded with some goods, although the sleeper replacement work in the Shenzhen section has been completed, in my opinion, the restriction is too great, and it is very good to reach 80km/h." ”

Prior to this, the freight train of the Shentan Railway traveled at a speed of 45km/h-55km/h, but now Zhang Haipeng has increased this speed by 70%, which can be said to be quite conservative.

As the leader of the chief engineer's office, he has mastered the technology of the railway, and everything is based on technology, which is why he dares to say this. The reason why the freight car is still pulling some goods is also the result of everyone's discussion, the reason is very simple, I am afraid that the train will go too fast and cause derailment.

When Chu Jianghe heard this idea, he just smiled and didn't say much.

"I think it should be able to reach 100km/h, the average speed of the previous train can reach 50km/h, now there is only half of the freight car, and there is not much cargo in the car, and the traction of the locomotive has also been enhanced, and it should not be a problem to go up to 100. A leader of the maintenance section said at this time.

In the Chutan Railway Bureau, there have long been rumors that after the electrification transformation, this line will challenge the speed of 160km/h under the traction of electricity, so in his opinion, this trial operation, reaching a speed of 120km/h, should not be a problem.

In the end, except for Chu Jianghe and Zhao Zongrong, everyone else finished speaking, and most of the people's guesses about the speed of this trial operation did not exceed 100km/h, which is quite conservative.

"Jiang He, what is your opinion?" Zhao Zongrong finally asked Chu Jiang Dao.

At this moment, the train has started and slowly exits the station.

Chu Jianghe was slightly stunned, he pondered for a moment before he spoke: "Zhao Ju, in fact, I don't know much about railway matters, especially the speed of train running, but in my opinion, the latest internal combustion car head has been replaced, and the sleeper replacement work in the Shenshi area of the Shentan Railway has been completed, and the maximum speed reaches 120km/h, it should not be a big problem." ”

"Impossible, young man, do you know what conditions need to be met for a train to run at a speed of 120km/h?" Zhang Haipeng immediately retorted.

As the leader of the chief engineer's office, he has the right to speak in this area, after all, he graduated from this major.

In the face of Zhang Haipeng's rebuttal, Chu Jianghe was not angry, but smiled and said: "Mr. Zhang, what conditions should be met to reach the driving speed of 120km/h, I really don't know, but Zhao Ju didn't say let us guess, my idea is very simple, after the electrification transformation, if the speed wants to enter 160km/h, before changing the 60 rails, if you can't even reach 120km/h, I don't think this test section can be done!"

PS: Everyone recommends the ticket to go, thank you.
