Datang: God-level Choice

Qin Huaidao smiled and said

"As the saying goes, the troops and horses are not moved, and the food and grass go first. There is indeed some truth to it."

Li Ershen, who has many years of experience in leading troops into battle, nodded with emotion.

Laying down the prairie, there is a series of layouts before, it is not difficult for Datang

What's really difficult is the logistical problem of long-term rule

Needless to say, just starting from Chang'an City and heading to Congling Mountain is nearly [-] miles away. Even the cavalry will take more than a month to reach it.

And if it is replaced by infantry, this time will be added several times.

"Seven two twenty zero"

This is because Datang has already built the cement straight road to Suzhou and Shazhou, otherwise it would take two months for even cavalry to reach Congling.

And after the battle, the problem is how to develop the prairie, no better than Persia, which has a very good background. In fact, except for a small number of powerful people, the prairie is all poor herdsmen.

Whether it is arms, food or materials, it must rely on external output

This poses a great challenge to transport capacity

In particular, the prairie is also connected to the more distant Persia. If you want to really connect Persia and the Tang Dynasty, the cement road is still a bit reluctant.

Such a huge volume of material transactions can only be achieved by railways and trains

Compared with highways, railways not only have stronger carrying capacity and lower unit cost, but also the trafficability and continuity are far from what the highways can match.

A steam car normally pulls several thousand kilograms of cargo, while a freight train can easily pull hundreds of tons of cargo, which is not of the same level at all.

If you want to truly rule the entire prairie, as well as radiate to the more distant Persia and the future food country and East Rome, you must have a railway! Even in the 20th century, the length of the railway is an important indicator to measure the comprehensive strength of a country. The importance of railway

"When will this railway and train be completed?"

Li Eryi said with a moving expression on his face.

For Qin Huaidao's ability, he has long been very trusting, especially with steam engines and steam cars in front, it is reasonable to invent a more powerful train

As for rail transportation, as early as the Qin and Han Dynasties, there were rails specially designed for carriages to travel, and Li Er was no stranger to it.

The only question is when will it be finished?

"The locomotive has been tested almost

At present, the first one can be officially put into use, and the railway to Luoyang City is already under construction, and it is expected to be completed within a month.”

Qin Huaidao thought for a while.

With the economic development of the Tang Dynasty, Luoyang City has become one of the most prosperous cities in the whole Tang Dynasty, and the transportation from Luoyang to Chang'an City is still a bit unbearable even after the waterway has been repaired many times and two highways have been built. Therefore, the location of the first railway in Datang?It is of high strategic significance to reach Luoyang in Chang'an City

As long as the city of Chang'an and Luoyang are connected by railway, and relying on the convenient water transportation conditions of the Grand Canal, the entire transportation artery will be strengthened in an instant.

This contract touches the [-]-mile railway. For the Datang Research Institute and the Ministry of Industry, which have rich construction experience, the various preliminary preparations plus one month of construction time are enough.

And the railway to the prairie and Persia has already entered the agenda, and preliminary exploration work is underway

Once the railway is almost built, it will be the time when the prairie is officially incorporated into the Tang Dynasty.

"Very good, then I can take the train to Luoyang, and then set off from Luoyang to Mount Tai"

"As for the prairie, I can afford to wait for a year and a half. I'm not in a hurry, I'll be safe."

Li Er nodded with satisfaction.

It is always a good thing to have less casualties when it comes to fighting such a thing, especially the prairie that has been infiltrated by the Tang Dynasty.

Moreover, it is easy to destroy and difficult to build. Li Er also hopes to obtain a more complete grassland with the support of the people, and can remove the powerful and powerful people on the grassland by the way, so that the property of these powerful and powerful people can contribute more to the Tang Dynasty.

As the self-proclaimed No. [-] king of the Tang Dynasty, Li Er is also full of curiosity about all kinds of new things. The launching ceremony of the steam car made Qin Huaidao show that the steam train set sail for the first time, and Li Er naturally wanted to fight for it. first

Moreover, according to Qin Huaidao's introduction, a train is enough to carry hundreds of people, and the comfort level is much higher than that of a carriage. At that time, the entire team going to Fengchan in Mount Tai can be handled by a single train "no problem"

Qin Huaidao smiled slightly, Li Er voluntarily advertised for railways and trains, what could Qin Huaidao be dissatisfied with?

"By the way, what is the price of this railway"

After forcing Wang Li Eryang to be complacent for a while, he asked curiously.

Now, under the guidance of Qin Huaidao, Li Er and others have begun to have a preliminary economic awareness and are extremely sensitive to various data.

"It's about [-] million."

Qin Huaidao spreads his hands

"Ten million, seven hundred miles, almost fifteen thousand a mile, a thousand miles."

Li Er couldn't help but took a deep breath.

Such a high cost, even though the national treasury of the Tang Dynasty has been improved a lot thanks to Qin Huaidao's efforts, it is still a bit overwhelming.

"The cost of construction will inevitably be high for the first time. After that, it will be about [-] pieces per mile."

Qin Huaidao explained with a smile

"It's no wonder that my son-in-law is in a hurry to lay down the Japanese island. Without the subsidy for the gold and silver mines of the Japanese island, this railway, even my Tang Dynasty, can't be built for long."

Li Er smiled bitterly.
