Datang: Li Shimin begged me to rebel

The soldiers of the Sixteenth Guards of Chang'an started a new round of training. Together with the first batch of students of the Joint Command Academy, the recruitment of the second batch of students is temporarily suspended. The second batch of students will probably not be recruited until the 24th year of the Tang Dynasty.

After Li Ke arranged them, he didn't pay attention to this matter.

Because there is still a brand new thing waiting for Li Ke to verify it.

At the end of June in the 23rd year of Zhenguan in the Tang Dynasty, located in the west of the Weishui River in the west of Chang'an City, a building with a large area was officially hammered in the last nail. This nail was hammered in by Li Ke.

Well, the sense of ritual is still very important.

As Li Ke hammered the last nail, all the people on the scene began to applaud warmly, and many workers couldn't help cheering directly, because this road was finally completed after two years of work!

On the roadbed more than one meter above the ground, sleepers soaked in coal tar were laid on the gravel, and four slender rails stretched directly into the distance.

This is Datang's first fully completed railway!This is also the most primitive railway, and the technology used is estimated to be the technology of Li Ke's previous life in the 30s and [-]s, but it has been optimized and the construction process has been optimized.

Its service life may not be very long. If it is used frequently, there may be problems with its rails after more than ten years, and the rails, sleepers, etc. will need to be replaced at that time.

But it doesn't matter, Datang more than ten years later has enough new technology to replace the brand new railway sleepers.

And now, the building they are in is Chang'an West Railway Station, the first railway station in Datang. About three kilometers away from this railway station, there is a one-way railway connecting here, and there is the first railway station in Datang. Steam locomotive factory.

At this moment, Datang's first train has been prepared in the maintenance station of the railway station.

Its entire steam engine technology is already very advanced. Although it is still a coal-burning steam engine, many of its technologies are actually very advanced. After all, Li Ke has a complete technology tree here.

The steam trains in history have reached this point after a long period of development. After all, the improvement of some small parts inside may take several years, or even ten years.

Such as preheaters, smoke deflectors, obstacle removers, etc. With these relatively advanced designs, coupled with optimized manufacturing solutions, some difficult designs were eliminated, and this unique neat train was born. front.

It can reach a speed of 40 kilometers per hour under full load. This speed is not even comparable to the running speed of a war horse, but its endurance is much faster than that of a war horse.

And in the empty state, its top speed is not high, about 60 kilometers per hour. It's not that it can't run faster, but its wheels, bogies and other structures can't support it. out faster.

In fact, the safe speed it sets is 50 kilometers per hour.

The longest running time for a single water filling is about nine to ten hours. It is designed with a special water tank and a carriage for pulling coal.

And its highest mounted carriage is seven standard carriages, and the number of load personnel in each carriage is 200 people.

Of course, it is impossible for so many carriages to be used for pulling people, and it can only have five carriages for pulling people at most.That is, the maximum number of passengers is about 1000 people.

If it is pulling people, this train cannot be fully loaded, not counting the weight of the carriages, it can only be considered fully loaded when it is fully loaded and can pull about 400 tons of goods.

In fact, the potential of this steam engine is still huge. With the advancement of production assembly technology and materials, the maximum traction quality of this steam engine alone is estimated to be able to reach about 2000 tons.

If you want to improve further, you need to continue to upgrade your technology.

But this technology is enough for the current Datang.

"Have you tested it?" Li Ke looked at the craftsmen in front of him and asked. Almost all the craftsmen in the industrial zone rushed over this time. Although many of them have nothing to do with steam engines, they can gather almost all of the current Datang. A masterpiece of technology.

"Your Highness has been tested. From the production factory to here, we have tested it several times. Its operation is very stable, and this steam engine itself has been changed to a power output. It has been tested for a long time in some factories and iron ore factories. However, there is no problem with it!" Lu Daqiang said excitedly.

"It's just that we haven't tested from Chang'an Station to Chencang Station. The total length of this railway is about 176 kilometers. According to the average speed of this train at 50 kilometers per hour, we can get there in about three hours! In half a day we You can even walk back and forth!"

Li Ke nodded in satisfaction, then looked directly at Xu Song behind him and said, "Go, announce the good news, and tell my father, including all the officials in the three provinces, that those who can be in Chang'an City will arrive here tomorrow. Test a new mode of transportation!"

"Yes!" Xu Song was also a little excited. He didn't know how the giant steel dragon in front of him was made, and it ran so fast and could pull so many people.

200 people in one compartment?In Xu Song's view, such a carriage can easily accommodate 600 people. Even with five carriages, this means that an army of nearly 3000 people can be transported at the same time!

3000 people, one hundred miles per hour, more than 2000 miles a day!What is this concept?How many times faster than before?

That's too fast, and there's just too much cargo to pull.

Xu Song's actions were very fast. Several young eunuchs got on their horses and rushed towards Chang'an City at the fastest speed.

His Highness said it was the fastest speed, so they directly used the privileges His Majesty gave them.

Although it wasn't a rush of [-] miles, it went straight to Chang'an City in a rush of [-] miles.

The horseshoeed horses galloped on the road, while the knights on the horses kept shouting "King Qin Jizuo" loudly. Hearing the roars of the knights on the horses, the pedestrians on the road gave way to the main road. , in fact, the official road built by Datang, although currently under the promotion of Li Ke, the way of walking up and down the road is carried out.

But in the central part of the road, the people have never been allowed to walk freely, in order to prepare for these cavalry who pass the news.

When the cavalry rushed into the Taiji Palace, Li Shimin was a little stunned. Li Ke didn't leave Chang'an City, so what's the rush?Didn't he say that the construction of the road between Chang'an and Chencang is about to be completed?He went to observe the scene. This is...there is a result?

"Xuan." Li Shimin announced the person in immediately.

The eunuch who came in was selected by Chang Lin himself. Li Shimin had seen all these eunuchs before, so he recognized them.

"I would like to report to Your Majesty, His Royal Highness King Qin hastened to complete the construction of the new road between Chang'an and Chen Cang. His Highness suggests that His Majesty take all the courtiers in Chang'an to test the new transportation method at a location west of the Wei River tomorrow."

"His Highness also said that all princesses and princes can go to watch the ceremony."
