Chapter 2412: Express train

These two technologies were both proposed by Qin Guan before. The high-speed railway is not only related to the development of the motherland’s transportation industry, but also related to the issue of future military deployment during the war. Therefore, Qin Guan found a prototype of the high-speed railway from the cemetery and gave it to CSR and CNR for joint research. The most important thing is the traveling system, which is the high-speed gears and bearings inside. Once this is done, everything else is easy. Up.
As for the technology of the anti-stealth machine, it is even more critical. It is the key to the new three fights and three defenses. Now that these two technologies have made major breakthroughs, how can Qin Guan not be excited?
"Okay, I have to see these two aspects, Xiucai, you can arrange for me." Qin Guan said.
Xiucai's work efficiency is quite high, and Qin Guan came to CSR in the afternoon.
CSR is mainly engaged in urban trams. Of course, it has more technical reserves for electric locomotives. When Qin Guan came to the factory of CSR, he saw several beautiful new urban rails being assembled. The tram, however, didn't care about these Qin Guan, accompanied by the person in charge, went straight to the prototype high-speed railway.
"Lao Li, Lao Li!" The person in charge shouted from a distance, "Look, who is here?"
Hearing the sound, Lao Li came out of the sample car. He was wearing work clothes with some oil stains on it. When he saw Qin Guan, his face was immediately full of joy: "Mr Qin!"
Lao Li was full of admiration for President Qin. When President Qin proposed to build high-speed railways, Lao Li was cynic, because Lao Li was familiar with the technology of high-speed railways. A small bearing and gear could not be made by himself. Yes, this is determined by the most basic industry. It is definitely not an exaggeration to say that the island countries have advanced industries.
However, President Qin decided to start, and he also said that the manufacture of gears was handed over to the northern heavy truck factory. Lao Li did not take this into account. However, when the northern heavy truck factory will process the gear according to the design drawings When the gears were handed over to them, they were all surprised from ear to ear, the error was completely within the required range, and the strength of the materials used was sufficient! At this time, they learned that the country has developed quite rapidly in the past few years and that the country already has this kind of industrial foundation.
Now that there are such things, what else to say? Do it! They delved into prototype cars, understood the technology, and on this basis, imitated the locomotive in front of them.
"Oh, sorry." Lao Li came up and wanted to shake hands with Qin Guan, but when he reached out, he realized that his hands were full of greasy dirt. He quickly retracted and wiped his clothes twice before stretching out again. Coming out, I shook hands with Qin Guan: "Mr. Qin, it is nice to meet you."
In fact, even if he wiped twice from his clothes, the oil stains on his hands could not be wiped off. However, Qin Guan did not refuse. It was the hands of the working people who worked hard for the prosperity of the motherland. hand!
"Come on, President Qin, take a look at our locomotive." The person in charge was also very proud of him, and instructed Qin Guan the vehicle in front of him: "We entrust the processing of many parts of this car to aviation companies."
The previous train did not require too high processing technology, but now it is different. If you want the train to run at a speed of more than 300 kilometers per hour, there must be aerodynamic requirements. This high-speed train is People call it a bullet head because its front is streamlined and looks like a bullet.
CSR does not yet have this kind of processing technology, so it turned to aviation companies for help. For example, the shape of the front of its car, for example, the curved windshield in front, can only be processed by aviation companies. come out.
This streamlined front, looks really beautiful!
"If you want to achieve high speeds, you need advanced power." Lao Li on the side is already an important scientific and technological person in the development of this kind of train. He introduced to Qin Guan: "As we said before, the train runs fast. It all depends on the headband. However, for this kind of high-speed train, only the front of the car is not enough. The wheels under the car are also powered, so that the speed can continue to increase. Now our group is only experimental. There is one head and three sections. The power car is composed of three cars without power."
The train is very long. This kind of train with only six cars can only be a trivial small train. Like the freight train, there are dozens or even hundreds of cars running on the track. At the time, it was like a long centipede.
Although the train is not long, its speed is enough for people to be proud of. It can reach a top speed of 300 kilometers!
"Our most advanced power system is completely manufactured by ourselves. None of the parts on it are imported from foreign countries." Lao Li continued: "During the test, our power system has also withstood the test, and there was no oil leakage or leakage. Phenomena such as cracks."
While talking, Qin Guan had already entered the carriage.
At this time, the train has just been developed. The interior of the carriage is empty, and seats have not been arranged. Even in the carriage in front of you, the floor has been disassembled, revealing the motor and other mechanisms below. Just now, Lao Li works here.
"The power equipment here is still undergoing final debugging. After the debugging is completed, the experiment can be done. However, we have a new problem." Old Li said to Qin Guan: "We don't have a suitable railway for it to run."
Railway is the main artery of the national economy, and railway transportation is quite busy. At present, many railways in China are actually overloaded. Freight and passenger transportation are used together, which brings great problems to dispatching.
It must first of all ensure the punctuality of passenger transportation. Therefore, many freight trains stop on the platform and wait for dispatch before they depart.
Now the train has gone through a speed increase, and the maximum speed has reached about 150 kilometers. However, there is still a big gap with the current high-speed train. Where can this high-speed train be tested?
If it is to test a train on an ordinary railroad track, a channel must be specially opened for it, and this channel should not be too short. After all, it takes time to speed up and slow down.
In this way, it will have a great impact on the existing railway transportation. If it is not tested, this technology will not be mature.
Railway transportation is the main artery of the national economy. It is impossible to stop transportation for a kind of train, right? If the operation is stopped for a few minutes, the loss can not be borne.
Now, after they have trial-produced prototype cars, there are such difficulties waiting for them.
