After more than a year and nearly two years of research and development, the latest trains developed by the University can already use three cylinders of steam engines to pull ten cars, and the speed has reached. When the car is empty, it is twenty-eight kilometers per hour, and when it is full, it is eleven kilometers per hour. Mobile terminals

However, despite this, this latest generation of trains still has a big disadvantage. It is that coal and water addition facilities must be installed along the railway, and a lot of time is spent on the way to add coal and water to the locomotives.

Later, at Li Yan's suggestion, the researchers used three to four locomotives as the power of a train one to two in front and one to two in the back. In this way, not only can the train come and go freely, save the trouble of turning around, but also pull and push, which can increase the power so that it can carry more cars, and then use more carriages to load coal and water. In this way, the train can run faster and run longer. In addition, this design has another advantage, that is, even if there is a problem with a locomotive, it will not delay the use of the train.

On this basis, some supply points are set up along the road.

This allows the big train to be put into use.

Compared with the immaturity of the train, Li Yan, a professional talent who knows about steelmaking, the large railway tracks are still very advanced, and are not much different from the railway tracks in later generations.

So, seeing that the train was barely put into use, Li Yan immediately ordered: Build the railway!

According to Li Yan's original intention, he first built a railway directly from Tokyo Bianliang City to Yanjing.

However

As soon as Li Yan's idea came out, it was immediately opposed by countless people.

Someone said: "Train is a skill, how can we get deeply trapped in it?"

Some people say: "Building a railway will cause me to lose my obstacles, harm my fields and hinder my Feng Shui, so I must not repair it!"

Some people also said: "Building a railway will waste people's money and waste national strength, which is tantamount to Emperor Yang of Sui's construction of the Grand Canal, which may bring great disasters!"

etc……

In short, many people stubbornly prevent Li Yan from building the railway.

Li Yan was too lazy to take a look at these people, and he regretted that the rectification movement ended too early!

But then again, there are some objective and realistic factors that even Li Yan has to consider.

For example, the production and transportation of rails.

Although Li Yan began to reform iron ore a long time ago and "fixed" the extremely advanced steel training technology, he ordered people to explore new iron ore.

But so far, the main thing is to rely on the six major iron ores, including Liaodong Iron Mine (Anshan Iron Mine), Xingzhou Iron Mine, Cizhou Iron Mine, Xuzhou Iron Mine, Yanzhou Iron Mine and Weisheng Iron Mine, the total output of these six major iron ores accounts for 95% of the country.

Let me explain it here, it is not that the steel produced by these iron ores is not enough for laying rails, but that the current transportation is really too difficult.

Therefore, when laying railway tracks now, we must consider the location of the iron ore, which can save a lot of time and cost.

In this way, Li Yan's original idea was to directly build a railway from Tokyo Bianliang City to Yanjing. In the current perspective, there are some things that are not very cost-effective. At present, the transportation of railway tracks and sleepers is very difficult. If you barely repair this way, you will have to pay a lot of money, which is really not worth the loss. After the railway is paved with a certain scale and find new iron ore, this problem can be solved easily.

Therefore, Li Yan could only temporarily make concessions to temporarily repair the Xiu of Xingzhou to Cizhou.

The reason I chose to repair this section first.

First of all, there are iron ore in both places, which is convenient for the start.

Secondly, this section of the road is a major transportation road and will also be a section of the main road in the future.

Again, the terrain here is flat and easy to repair.

At the same time, Li Yan ordered people to increase their efforts to explore new iron ore in later domestic iron-produced areas such as Sichuan, Hebei, Shanxi, Shandong, Anhui, and Hubei.

As for the distribution of iron ore in Goryeo, Japan, Taiwan and the southern region, Li Yan was not very clear about it, so he could only let the local government explore it bit by bit.

In short, Li Yan asked someone to look for iron ore nationwide, and then built steel mills to produce iron rolling at the location of the iron ore, preparing for the next step of laying railways across the country.

This is undoubtedly a big game of chess. It takes countless years to complete it. It is possible that Li Yan will even die. The "nine vertical and nine horizontal" railway that Li Yan wants to see and the "Belt and Road" dream that the "Belt and Road" will not necessarily be realized.

But despite this, Li Yan still withstood all the pressure and forced the matter with an iron fist.

In order to better implement his ideas, Li Yan ordered the establishment of a Ministry of Railways, which was personally responsible for it, and appointed the capable Hu Shijiang as the Secretary. In addition, in order to ensure that the Ministry of Railways has sufficient money to build the railway, and in the future, the Ministry of Railways not only did not require the court to invest money but also made money for the court. Li Yan transferred Zhang Xu, who was very good at making money and managing finances, as the Minister of Railways, as the Minister of the Ministry of Railways.

While overhauling the railway, Li Yan did not forget about the development of the train.

Given that the prospects of steam locomotives are not great and will sooner or later be eliminated by more advanced technologies, Li Yan formally proposed the concepts of "diesel locomotives" and "electric locomotives".

The advantages of internal combustion locomotives are fast startup and high horsepower, high thermal efficiency. The disadvantages are complex structure, high manufacturing and maintenance costs, and high pollution.

The advantages of electric locomotives are that the thermal efficiency of steam locomotives are twice as high, with large power, strong overload capacity, large traction force, fast speed, short preparation operation time, small maintenance volume, and low operating costs, which facilitates the realization of multi-machine traction, regenerative braking and energy saving, and will not cause air pollution and low noise.

From Li Yan's subjective wishes, Li Yan certainly hopes to develop electric locomotives.

But this electric locomotive has higher requirements for technology, especially when "electricity" has not been widely discovered and used.

In addition, although internal combustion locomotives have many disadvantages, their advantages are also very obvious. That is, internal combustion locomotives can carry fuel and water themselves. As long as standard tracks are given, they can operate at any time without being affected by other aspects. Unlike electric locomotives, they have very high requirements for all aspects and have limitations in their application areas. They can only be used as transportation tools for electrical railways.

The most important thing is that Li Yan doesn’t know where scientific researchers will make breakthroughs and make progress, so it is also good to have one more research direction.

In short, although it is controversial and has many difficulties, the "big railway" plan named by Li Yan himself was forced to do so under the iron fist of Li Yan.

On the day the Ministry of Railways was established, Li Yan said to Wu Shijiang and Zhang Xu: "I want to move the capital by train. I hope that my two beloved ministers can satisfy my small wish."
