There is nothing difficult in the world, I am afraid that those who are determined will have one day to overcome any major difficulties. With Yang Cong's unremitting efforts, the problem of steam locomotive steering and wheel linkage has finally been solved, and at this time, half a year has passed.

This progress cannot be said to be fast or slow.

If you want to say it quickly, Yang Cong just copied it. It was not considered a redesign at all. It took half a year and it was really a bit long.

To be slow, this thing is not very difficult. In addition, Yang Cong is not a professional designer, so it is good to be able to complete it within half a year.

Next is the manufacturing and overall assembly of the carriage. Yang Cong and Wang Xuanyi jointly installed four sets of steam engines about one foot to ensure the output force.

These jobs do not have much technical content, and they are just an assembly process. In less than a month, samples of the first steam locomotive were released.

That morning, it was still after the Dou Mao, and Yang Cong took his disciples excitedly to the railway around Yuyuantan.

At this time, people were gathered next to the steam locomotive, including three layers inside and three layers outside, including disciples from the School of Physics, students who came here to see the fun, and people nearby rushed to see the fun. In total, there were probably thousands of people.

These people can be said to be recruited by Yang Cong, because he issued a notice early that an important test would be conducted this morning, and all disciples from the School of Physics must be present to observe.

When the disciples of the School of Physics knew, their relatives and friends knew, and when their relatives and friends knew, many other related people knew. In addition, Yang Cong did not stipulate that others were not allowed to come and watch, so the sides of the railway were naturally surrounded by people.

This guy, this steam locomotive is really spectacular, ten feet long, ten feet tall, and ten feet wide. It is like a city wall. Nowadays, who has seen such a big car, and who would be bored to build such a big car?

Moreover, in order to please Jiajing, Yang Cong specially ordered people to make the front of the car look like a faucet. The longan is the cab, the dragon nose is the chimney, and the entire carriage is covered with golden copper scales. Just looking at the appearance, it can make people feel excited and magnificent.

The people who watched the fun were talking with relish, and the students of the School of Physics couldn't help but whisper there. As soon as Yang Cong arrived, the buzzing discussion suddenly stopped, and everyone looked at him with respect, and that look was not pretending.

At this moment, Yang Cong's reputation is not a big deal. Although he does not have the name of a sage, he has been praised as a sage.

The sage-like figures are coming, but everyone is still standing still!

Yang Cong was already used to this scene. He smiled and bowed his hand to signal a circle, then strode through the passage that the crowd automatically gave out, came to Wang Xuan, and said a little excitedly: "Sir, are you all ready?"

Wang Xuan said excitedly: "Everything is ready, the firewood is lit, the water inside has been boiling for a while, and it is probably going to be turned on long ago."

Upon hearing this, Yang Cong couldn't help rubbing his hands and said tremblingly: "Okay, I'll go up and try it."

After saying that, he was going to walk towards the motorcycle's ladder.

Seeing this, Wang Xuan hurriedly grabbed him and advised: "Qingfeng, it's dangerous. No one has opened this thing. What if something goes wrong? Didn't you say that many experiments are dangerous and may cause death? Or do I go, you're here to watch."

Yang Cong shook his head repeatedly and said, "How can that be done? You haven't opened it before. I have a constitution in my mind. Do you have it?"

this!

When Wang Xuan heard this, he couldn't help but speak. He thought for a while, but shook his head and said, "No, Qingfeng, you are our backbone. What should we do if something happens to you?"

Seeing this, Yang Cong couldn't help but laugh and said, "Hahahaha, what's wrong with this? At worst, I'll drive slowly. Are you still afraid that something will happen to it? If something happens, it's also the thing it hits."

Upon hearing this, Wang Xuan could only say helplessly: "Okay, I'll go with you."

After saying that, he followed Yang Cong and was about to walk towards the ladder.

Seeing this, Zhang Juzheng and other disciples couldn't help but shout, "Mr., I'll go too, and I'll go with you too."

Yang Cong waved his hand and said, "Okay, you guys just watch it down there. There are so many people in the carriage."

Indeed, the carriage at this moment is actually a locomotive, with boilers, copper pipes, steam engines, spare firewood and clean water. There are not many places in the carriage that is ten feet long, and it would be good to squeeze in about ten people.

After Yang Cong got into the car, he took the initiative to sit in the main driver's position, which is the left longan, while Wang Xuan could only sit at the right longan to accompany him.

At this time, the water in the boiler had already boiled, and green smoke had already popped up from the two dragon noses. Yang Cong calmed down his excitement and shouted: "Hound the whistle, ready to drive."

Upon hearing this, Wang Xuan, a disciple, quickly opened the valve of the whistle.

"Woo woo woo woo woo."

A majestic and distant whistle sounded, and the people watching the fun around were stunned.

This whistle was also "designed" by Yang Cong. Although whistle flutes and other things are common these days, no one has seen anything like the whistle that makes a huge whistle sound when it is opened.

Is this sound the legendary dragon roar?

Before the crowds watching the fun could be realized, the steam locomotive in the shape of a faucet was slowly starting up amid the howling sound.

At the beginning, Yang Cong didn't dare to drive too fast. He just opened the valves of two sets of steam engines. The thrust was a little small. The steam locomotive was really "climbing" on the rails, which was slower than the average person's walking speed.

However, this is already magical enough, because such a big guy, no one pushes or pulls, can actually move on his own. If it weren't for the past, who would believe it if he said it.

When the crowds watching the fun around thought that the "Fire Dragon Car" was at this speed, Yang Cong suddenly gritted his teeth and opened the valves of the other two sets of steam engines.

This guy is amazing. The steam locomotive suddenly accelerated like a medicine. Moreover, the speed is getting faster and faster. At the beginning, people can still follow the jogging slowly, but people can't keep up even if they run hard behind them.

That speed is like a galloping horse.

On the steam locomotive, Wang Xuan looked at the flying scenery on both sides and couldn't help but said nervously: "Qingfeng, hurry up, close those two sets of valves, this is too fast."

Fast?

Maybe it's a little bit.

However, this speed is much slower than that of trains in later generations.

Besides, the railway around Yuyuantan is a circular track at this time. No matter how fast it is, it will never start. It will only circle around Yuyuantan.

Yang Cong said calmly: "This speed is not too fast, but it is indeed a bit too fast when turning and entering the station. It seems too slow to open only two sets of steam engines. This is indeed a problem."

After saying that, he turned off the valves of the two sets of steam engines and sat there to ponder.

At this time, they designed two-sided drives, that is, two sets of steam engines drive the wheels on both sides at the same time, so they drive two sets at the same time each time, and it is not impossible to change to drive together, but the mechanical structure is more complicated.

After thinking about it, he decided to adjust the air pressure so that it would come faster.

Thinking of this, he pointed to the steam valve and said, "Sir, we have to improve this thing. We cannot open it all at once, and we must close it all at once. Threads must be added, slowly opened or closed it slowly to adjust the steam pressure. In this way, the speed of the entire steam locomotive can be controlled at will."
