Above the court, no one objected to the issue of the Dongping Railway, and under the court, many powerful families and nobles began to rush to the northwest.

After careful consideration, Han Qi only reviewed the personnel slightly, as long as it was not a person who could not support the wall with complete mud, basically, they were all released.

It turned out that the petty officials who were almost disdainful, the six or seven grade officials in the northwest, were placed in Bianliang in the Northern Song Dynasty, so they were really petty officials like sesame mung beans, and these children of the powerful in the past were absolutely disdainful, and only those who made big mistakes or fell in the competition would consider it.

Now, let alone six or seven grades, there are very few such official positions, and those who have no foundation can hardly be earned, but some smaller officials, from the eighth rank or even the ninth grade, have been contested.

The northwest is vast and sparsely populated, the number of officials is very small, and sometimes there is only one Qipin to manage the huge territory, but the income from this territory is huge.

Now, after refinement, a relatively normal situation has emerged, with the gradual subdivision at the county level, and every village and even town has a place under its jurisdiction, and some officials are even high-level and low-level.

Such a trend, so that countless talents to the northwest, but also to a certain extent, changed the fate of the entire northwest, the Hetao Plain, which is located in the middle of the Yellow River zigzag position, itself is a piece of anointed land, with the plug in the south of the Yangtze River, it is definitely not an exaggeration.

The climate change makes the climatic conditions here not as good as the Han Dynasty, but it can never be called worse, but before, it was controlled by the Western Xia, in the border area, and the impact of the war made it impossible to develop it completely.

Now, the Western Xia is controlled by the Liao State, which is equivalent to saying that the enemies of the Northern Song Dynasty have suddenly changed from two to one, although it is said that the strength of the Liao State will increase even more, but if the Liao State attacks from the Western Xia side, they will not get any benefits.

The core area of the Liao State is in Hebei in the later generations, and the area of Liaoning is relatively far away from the Western Xia, and the battle of Liaoxia is a real fire, so to speak, and the Liao State lost that kind of wear, and the Western Xia is definitely not good, that is, the Western Xia, which has a population of several million, was killed and sold most of it at once.

In this case, the relatively barren control of the Liao State in Western Xia, coupled with Yuan Hao's retaliation, suddenly caused the Liao State to lose several millions, and in this case, the possibility of them attacking from the northwest was reduced to a very low level.

It's not impossible, but the probability is too low, and the Northern Song Dynasty will not be completely undefended, but it will greatly reduce the number of garrisons, and similarly, the development of the northwest has also begun.

The Hetao Plain has also become the finishing touch, the huge cultivable land, a variety of advanced agricultural machinery obtained from the Dinghai Navy, plus some agricultural planting technology, these three upgrades, combined together, have formed the current miracle, the harvest of 120 million stone grain, even if it is not transported to the Central Plains, it is enough to make the development of the northwest without any deviation.

In a feudal society, or even a society with advanced science and technology, food represents the foundation, no matter how much money you give, no matter how much advanced science and technology you have, without food, it is enough to make the society chaotic, let alone in the feudal dynasty.

The purpose of these nobles is not pure, they are to use the northwest as a springboard, this, some people who are addicted to cleanliness will feel uncomfortable, but Han Qi is not, he has always been a person with a strong purpose, these families joined, they did a free ride, but correspondingly, they want to provide some help for such a free ride, mainly in terms of resources, some policies can be passed faster, and then promote the development of the northwest.

When the younger generations are in the next generation, and there is also the exchange of political resources, Zhao Xin is also busy.

The construction of the Dongping Railway is almost certain, from 120 million stone of grain, and every year, almost 24 million stone of meat, this is enough to overwhelm everything, which almost represents the ration of tens of millions of people, not to mention, as well as various minerals located in the northwest.

If these grain, meat, and mineral resources can be used reasonably, the annual increase in fiscal revenue for the Northern Song Dynasty may exceed 25 million yuan, which is almost the previous fiscal revenue of the Northern Song Dynasty in one year.

When I do something else, I still have to worry about whether these things can be sold, and it is not uncommon for Gu to hurt the peasants, but with Ding Haijun, anything can be eaten.

There is too much grain, no problem, you can make wine, you can make something else, such as compressed biscuits, and some other grains that can be stored for a long time, even if they are stacked, they are better than the original storage in the Northern Song Dynasty.

Ensuring dryness and low temperatures allows grain to be stored for at least three years, or even more, which greatly strengthens the ability to cope with disasters.

The short shelf life of grain is a big problem, even if there is a bumper harvest for three or five consecutive years, once there are two consecutive years of catastrophe, it is easy to cause bad things, and Ding Haijun can act as a beat to ensure that the grain can go where it is needed.

Since it was decided to build it, then the whole plan must be determined, which is different from the railway from Yingtianfu to Bianliang, which is a long-line railway, and the geographical environment involved is also different, and even the problems that may be encountered are completely different.

A 2,000-mile railway is not the same as a 300-mile railway.

The 300-mile railway, as long as you take into account the shortest straight line between two points, is the most important thing to consider is to cross the river from that place and go around the mountain from that place.

However, a 2,000-mile-long railway, it is different, we must comprehensively consider, how to build the most convenient, how to build, the most economical construction period, and a series of problems such as economy.

At the time of the construction of the railway from Bianliang to Yingtianfu, Zhao Xin had already begun to prepare for other railways, and at that time he was only preparing to build the railway from Variable to Jingzhao.

Jingzhao Mansion, itself used to be the core of Guanzhong, once eight hundred miles, is also a fertile soil, but over-development, as well as the impact of climate, let them decline, but now, the redevelopment of the Hetao Plain, so that this road has a foundation for development.

Now, with the right to build the entire railway from Tokyo to Seoheifu in place, the exploration and planning of the entire railway must be raised to a certain extent.

China's topography, high in the west and low in the east, in the northwest is a layer of high mountains, the east is a series of plains, under this topography, Henan is just in the center of the whole China, from Henan to the east, is a plain, the terrain is relatively gentle, there are few mountains, but from Henan to the west, it is a mountainous area.

Henan Mansion is one of the four capitals, and before that, he also had a famous name Luoyang.

At present, in the history of China, if there is a famous city, then there is a Chang'an and a Luoyang.

They were not only the capitals of the Western Han Dynasty and the Eastern Han Dynasty, but also the capital and capital of the Tang Dynasty, and had a very terrible strategic position.

After the establishment of the Northern Song Dynasty, I also thought that the capital was Luoyang, but after years of war and destruction, Luoyang was relatively dilapidated, and none of them became the foundation of the capital.

Even after the changes of the times, many things are different from ancient times, but in terms of geographical location, there are still few changes, and the reason why Henan has become the capital of the civilized world, the geographical environment is a very important factor.

It is bordered by the Yellow River in the north, Luoshui in the east, and there are eight passes around it, such as Taigu, Guangcheng, Yique, Yuyuan, Revolving Gate, and Mengjin.

Whether a city can become the capital, geographical location is the key, in the previous period, Chang'an has become the capital for a long time, on the one hand, the fertile soil of the Guanzhong Plain, on the other hand, it is not such a checkpoint as Hangu Pass.

Luoyang is also similar, once in the Eastern Han Dynasty, holding the Tiger Prison Pass, you can resist the soldiers, as long as you hold it, you can keep all the dangers out.

On the contrary, Bianliang does not have such an advantage, once it breaks through the Yellow River, there is no place to defend, although it is difficult to break through, but at some specific moments, there is no problem at all to break through.

When building a capital, it is necessary to consider the issue of safety, the easier it is to defend, the better, but when building roads, especially railways, it is necessary to consider the convenience of transportation.

Eight passes and the periphery of the defense system, constitute Luoyang strong as the capital of the foundation, but also become the current dilemma, in fact, the canal in the Northern Song Dynasty, only to Kaifeng, from Kaifeng to Luoyang a section of the canal, is intermittent, this has also become a key trouble, now, a railway through, so that this problem has been solved.

There are many checkpoints in Luoyang, but the Yellow River Plain is mainly flatland, and these mountains are not so high, not as steep as the Qinling Mountains, and they can still solve the problem.

In fact, in the preliminary survey work, a key point of this railway is still in Guanzhong, which is a difficult problem to solve.

The reason why Guanzhong is terrible, on the one hand, is that the river is on the river, the pass of Sanmenxia is terrible, so that the river is transported here to end, the Yellow River from the plateau in the middle reaches, to the plains in the lower reaches, the drop is very large, and the Yellow River carries sediment, and there is no large amount of accumulation in the middle reaches, the reason is that after the middle reaches pass the Loess Plateau, the drop is huge, and the flow speed of the Yellow River water is very fast, so that the sediment does not have the conditions for accumulation.

However, after passing through Sanmenxia, along with the gentle terrain, the water of the Yellow River carried kinetic energy and began to flow towards the ocean, but because of the gentleness, it accumulated on a large scale.

Although the Three Gorges has many risks, it is not completely impossible to go upstream, but in the Yellow River, this does not exist.

There is no way to reverse the current, there is no way to use the convenient water transportation of the Yellow River, and you can only take the land route, but the natural environment of Guanzhong also makes the land route impassable.

The steepness in the pass is the steepness of Hangu Pass

There is an idiom that can describe the steep pill mud of Hangu Pass, Qinling Hangu Pass, has become the key to restriction, to the 20th century, there are not many railways into Xi'an, and even close to the 21st century, the Qinling Mountains, is still a car is difficult to overcome the problem, the accidents that occur on this every year, I don't know how many, that is, to the 21st century, a large number of Qinling tunnels are excavated, which allows the traffic problem to be solved.

That's right, there is no dangerous peak that can't be crossed, if necessary, to develop external transportation, even in the Himalayas, it is not impossible to dig a tunnel, but in the Northern Song Dynasty in the 11th century, to dig a tunnel, it is an impossible task.

Without tunnels, the construction of the railway is much more difficult, and even some of the methods that have been proved useful in later generations have also been used at a pace, and the zigzag of the Beijing-Zhangjiakou Railway can only solve the slope of the hills to a certain extent, for the horse, the strength is still a little worse, and the slope has reached a certain level, and there is no way to continue.

It is precisely because the length of the railway is long enough that many of them are still on the plateau, the eastern part of China, is a large plain, to Henan, Hunan, Hubei this line began to gradually rise, the south is the Yunnan-Guizhou Plateau, the Sichuan Basin such places, in the north, is the Loess Plateau, Mongolian Plateau such places.

From one or two hundred meters above sea level, it has been raised to thousands of meters, or even higher, and in the middle, there are a series of mountains and plateaus, and the construction requirements for the railway have been raised to a considerable extent.

Zhao Xin is not unprepared, with his understanding of the map, as long as the original 21st century railway is reproduced, basically, a lot of things can be saved, and to this extent, the actual situation needs to be analyzed.

In the plains, you can use the method of detouring, the higher efficiency of the railway, even if it is a detour of dozens of miles, or even hundreds of miles, it is acceptable, but in the Guanzhong Plain, there is only one road, even if it is a few thousand miles, it is more than certain to be able to go out, unless it goes around to a place further north, which is not the territory of the Northern Song Dynasty.

The surveyors below, they only use large-scale field measurements, and then summarize the situation and hand it over to the top to deal with.

Ding Haijun's railway construction unit can be said to be very good and has a lot of experience, but at best, it is only a few hundred miles of railway, and how many things they have encountered cannot be compared with such a 2,000-mile long railway.

More problems gradually upward, but also to Zhao Xin here, although Zhao Xin does not know how to build a railway, but he has a wide range of knowledge, divergent thinking is stronger, some problems, in his hands can be easily solved, for example, to determine the direction, choose certain schemes, but only one of the biggest restrictions, Hangu Pass and Qinling, this point, can hardly be crossed.

This has also become the core problem that plagues the railway, if not solved, the start of the Dongping railway, will be far away, which will not only affect the improvement of the financial revenue of the entire Northern Song Dynasty, but also affect the future of the coal of the Dinghai Navy, there is no stable coal transportation channel, even if the steam engine is completed in the future, the promotion of the Dinghai Navy will also be affected.
