But since he had made a steam power machine himself, Zhao Long was more confident in making a steam locomotive.

There are hundreds of people in the village, and they have fully utilized the advantages of having a large population and a large number of firewood and high flames. In just one day, the railway project has made a lot of progress!

On the other side, Gongzi Gao, Jianglu and others immediately mobilized their troops after returning to Xianyang.

"Order Xianyang Camp to send 20,000 cavalry to rush to Taiyuan County and immediately get the carbonite!"

The young master Gao Ling said, "In addition, tell the county magistrate of Taiyuan County to immediately recruit another 50,000 garrison soldiers and transport charcoal to Xianyang! It should be fast and too many. This is an urgent military situation, and you must not be slackened in the slightest. Those who violate the order shall

Severe punishment!”

"promise!"

Twenty thousand cavalrymen took the order and set off immediately under the command of Jiang Lu and sent it to Taiyuan County.

Starting from the official road, this team can make the coming and going smoother and save a lot of time.

In a flash, a few days passed, and the first batch of cavalry finally transported the coals and transported them outside the mountain.

Prince Gao and Jiang Lu took people on horses and cloth bags and sent them to the mountains for transportation.

The project in the mountains has been almost completed after these days.

Of course, the reason why it is so fast is that there are many people and the other is that the requirements are low!

No matter what, as long as the requirements are low, it will be done quickly!

As long as you want to complete it quickly, lower the requirements.

This has been almost the case throughout history!

There are many advantages of low requirements, such as saving time and saving money.

Of course, the result often may be that bullets cannot be saved.

"Old Zhao, let's see where our shop is?"

Zhao Long brought his men to the forefront of the project and asked when he saw Ying Zheng.

"Sir, are you here?"

Ying Zheng knew this, "It was all arranged according to the teacher's arrangement, and it was almost the same as the one in front."

The route drawn by Zhao Long is, first of all, the distance is not very long, and of course, it cannot be endless, because it cannot be flat from the bottom of the mountain. It would be nice to choose some roads that are as flat as possible to pave the roadbed.

If it could be smooth along the way, then we could have stepped out a way long ago.

Secondly, it’s a problem of low requirements. If you hit the roadbed slightly, the mountains are full of hard soil.

Then lay gravel and sleepers.

When the rails are transported in batches, each of them is fastened with screws, and the simple finished product will come.

Of course, the key is that this car is not the existence of the cargo that is so heavy for so many people in later generations. The situation he weighs will not be so much, and the time will not be so intensive.

So, it is enough to make the foundation like this.

Of course, what the person you sits in or what the leader asks for will not be the same.

Moreover, when Zhao Long was designing, he also adhered to one principle, that is, energy conservation.

Of course, it is not energy-saving from bottom to top, but it is OK when it comes to top to bottom.

After all, the distance is short, and the rails can be regarded as sliders and slide down all the way.

In this way, a lot of coal raw materials can be saved.

"Indeed, the progress is quite fast, and the work is good. My steam locomotive is almost ready."

Zhao Long looked down and saw that after all, this thing is actually a ring buckle device, with little profound science and technology, so the requirements are not very high at all.

Ying Zheng’s arrangement is still OK.

"Oh? Is that right? Ying Zheng said immediately after hearing this. Since he was almost ready, why not give it a try?"

"Okay, it's over, so you can try it. The real train also needs to be tested, but our locomotive is a bit shabby."

Zhao Long scratched his head and smiled.

That's right, the cold is indeed a bit cold. It's impossible to be considered a real train. It's a steam engine at the head, and it doesn't even cover it, just a piece of wooden carriage.

At the end of the wooden carriage, seven or eight seats were left, that's all.

As for the wheels below, there are no tires or rails at all, but several lubricated connections and fixed bearings are made.

You said this is a train?

It is better to say it is the original steam engine sightseeing car in the park, and it may even become a roller coaster.

Of course, this was already a revolutionary progress for the Qin Dynasty.

His car is not good enough, and the tracks are not good enough, but he is the only one.

And it is the only one that can operate.

"Okay, let's try it."

Zhao Long looked at Zhang Han beside Ying Zheng and said, "Old Zhang, go with me?"

"I?"

After hearing this, Zhang Han felt a little moved, but he looked at Ying Zheng, "Village Chief..."

"If you want to go, just go."

Ying Zheng immediately smiled and said, "Sir, I value you very much, this is a good thing."

"promise."

After receiving Ying Zheng's permission, Zhang Han nodded and took the order.

"Sir, what is a gear shift?"

Following Zhao Long, Zhang Han asked curiously.

"Dragging gears, didn't our motorcycles also have gears before? However, this and that are both very similar and different."

Zhao Long smiled and said, "The starting of this train requires gear shifting. At first, wait until the cylinder is hot enough, and then close the gate and let the steam power drive the train through the device. This is gear shifting.

”

"Oh? But that's the case?"

Zhang Han smiled and said, "Then you have to see!"

Following Zhao Long, Zhang Han returned to the mountain.

"Let's go, I'll take you to get familiar with it."

"good."

The two walked over, Zhao Long sat on the first place, and Zhang Han sat aside, which was basically the same as the co-pilot's position.

The water tank had already heated up, and the fire soon became much bigger when the windshield was removed.

Zhao Long designed the boiler of this steam locomotive relatively large.

Because of this, the situation of adding coal in the middle can be saved.

The real train must be filled with coal all the time in the middle, because the distance is long and the load is load-bearing.

However, the journey of this train is very close, and there is no need to add coal once for several round trips.

Therefore, it is enough to design an air outlet to control the size of the fire.

"I'm sure, this thing is the starting gate, and the two next to it are gears."

Zhao Long smiled and said, "This gear is actually the air outlet. When the high gear is in the air outlet, all the air outlets of the boiler are opened. Generally, we only need to turn on the mid-range, saving money."

"good……"

Zhang Han listened while carefully watching Zhao Long's operation.

"Come on, start!"

rub!

Once the gear is hung, the train carrying the entire steam locomotive group is slowly started.

puff, puff, puff...

From slow to fast.

"Hi, it really tastes like that in the movie..."

Zhao Long smiled and teased Zhang Han, "I didn't expect that my buddy has come to help the poor but to invent it. Speaking of which, our Zhaojia Village is also special enough."

"This? Hehe..."
Chapter completed!
