Chapter 153 Discussion Tell Train
He did not deny Wang Luo's statement because he was engaged in research in the mechanical industry and should have some understanding of trains in various countries.

“Hello, sir. Of course I know what 350 kilometers means. Even now, no one in the world can imagine that a train can run so fast. But just because someone didn’t expect it doesn’t mean it can’t be realized in the future. You see, the earliest train was a steam train. Stephenson even raced against a horse-drawn carriage. When he invented the train, he didn’t expect that it would eventually replace the horse-drawn carriage.

Later on, diesel locomotives came into being, which defeated steam locomotives. In recent years, the most popular train in the world is electric locomotives, right? "

The professor opposite nodded, agreeing with what Wang Luo said.

"But electric trains are not the end. I feel that there should be two types of trains in the next step. One is the high-speed EMU passenger train, and the other, which I think is the final version, should be the maglev train. If these two types of trains appear, 350 kilometers per hour will not be a problem at all, and even 500 kilometers or 600 kilometers per hour will not be a problem!"

As soon as Wang Luo finished speaking, he caused an uproar among the people around him. Damn it, 350 kilometers is already boasting, why did you come up with an even more impressive number, 500 kilometers, 600 kilometers, what are you thinking, kid?

"I didn't expect you to know so much. No country in the world has started research on maglev trains yet. But the prototype of the high-speed EMU passenger train you mentioned appeared in the late 19th and early 20th centuries. At that time, Germany, France, Britain and other European countries began to test high-speed trains. However, due to technical and conditional limitations, the speed of these tests did not exceed 200 kilometers, and no country has put them into operation yet. Your ideas are very forward-looking!"

The old professor gave Wang Luo a thumbs up and praised him.

Everyone remember that high-speed rail is not a maglev train. The track of a maglev train is different from that of a high-speed rail. A maglev train is suspended when in operation, while a high-speed rail is a wheel-rail technology and can be connected to an ordinary railway with the same track gauge. High-speed rail uses a wheel-rail mode, can be connected to existing railways, and is cheaper. The difference between a maglev train and a high-speed rail lies in the processing of electricity.

Maglev trains are vehicles that use electromagnetic force to suspend the vehicle body on the track and drive the vehicle by electromagnetic force. High-speed rail is a wheel-rail system of transportation. Passenger dedicated lines are built and EMUs are run on them. The biggest feature of maglev trains is that there is no friction resistance that cannot be eliminated by the wheel-rail system. Only air resistance remains. The operating speed can exceed 400 km/h. The maximum operating speed of high-speed railways is 481.2km/h, and the test speed is 574.8 km/h.

High-speed rail is a transformer that connects 1500V high voltage electricity to pantographs and pantograph electric trains, with a speed of 360 kilometers per hour. Maglev trains are powered by magnetism and have a speed of 600 kilometers per hour. Moreover, maglev trains have three carriages in a train, while high-speed trains have six carriages in a train, so there is a qualitative difference between maglev trains and high-speed trains.

"Old sir, isn't my brother bragging?"

When Sha Zhu saw the old professor giving Wang Luo a thumbs up, he asked him curiously.

“I’m not bragging. What he said is theoretically feasible, but it is limited by the current industrial development. If the current development trend of the world’s industry continues, people may see what he said come true in the next 50 years.

Comrade, you know so much, can you tell me about your idea of ​​high-speed EMU passenger train? Maglev train is too far away, but this high-speed EMU has a prototype. "

The old professor became interested and asked about Wang Luo.

"There's nothing much to say about this. The kind of train we're riding on should be called a trailer, with a locomotive pulling the carriages behind it. The reason why a high-speed train is called a train is because its carriages are also powered by themselves, that is, each carriage has an electric drive device. With this device combined with the wires on its head, it can run quickly. If you want a faster speed, add a few more trains to carry more. If you want a slower speed, then bring fewer trains and more trailers. The principle is that simple. The key is that electricity must be guaranteed, and there must be a special braking system, operation management system, specific operation routes, etc. As long as these are researched and equipped, the realization of the train is not a problem at all!"

Although Wang Luo did not understand the specific details of the EMU, he still knew the basic principles like this. This was a common thing in later generations, and even elementary school students knew about it. After all, this was the flagship industry of the Dragon Kingdom in later generations, so he expressed his ideas.

I even asked the professor for a pen and paper, drew a picture of a bullet train, and gave it to him.

"Amazing, amazing, amazing, you know so much at such a young age, it's really amazing. What's your name, which school do you go to, what's your major, are you interested in applying to our school?"

After seeing the pictures drawn by Wang Luo, the old professor praised them repeatedly and asked about Wang Luo's academic performance.

"My name is Wang Luo. I just took the high school entrance exam this year. I applied to an accounting school. I plan to work as an accountant in the future. As for what I said, it's just theory and superficial understanding!"

"Oh, what a pity, what a pity! Why didn't you take the high school entrance exam? Once you're in high school, you can take the college entrance exam. If you're admitted to our school, or even better, our department, I'll personally guide you and let you understand the charm of mechanics!"

"I'm not interested in this. I'm just a salted fish, I don't want to move, I'll just let the sun bask in my water. I think accounting is a good job."

Wang Luo smiled and shook his head.

"How can you have such an idea, kid? The future country needs your participation, and the future industry also needs your participation. How can you just sit there and do nothing? This is not okay, it's not advisable!"

The old professor disagreed with Wang Luo's point of view on the spot. This was an era when everyone was striving for national construction, but Wang Luo said that he was a lazy fish. He felt that this was not good.

"There is no distinction between high and low jobs. I can contribute to the country as an accountant, and I think it is the most suitable job for me. Otherwise, without us accountants, how can the country's economy develop and how can data be compiled? Without us, wouldn't all walks of life be in chaos?"

"Yes, you are right. I took it for granted. When I see a good talent, I always unconsciously want to bring him to our school and department. Little do I know that other industries in the country also need professional talents. However, I am optimistic about your understanding of machinery. If you are interested in machinery in the future, you are welcome to come to Beijing Institute of Technology to find me. My name is Zhao Bingran. You will know it when you ask around at Beijing Institute of Technology!"
