Chapter 1111 High-speed rail plan, people-oriented
Dashu was stunned by the heavy-loaded locomotive described by Luo Chong. Those exaggerated data, compared with the small train he was riding now, were simply a world of difference.
You have to know that train carriages are three-dimensional. According to the data given by Luo Chong, the heavy-loaded locomotive, not counting the carriages, the rails alone are wider than the current carriages, and the width of the carriages is more than twice the current width, reaching an exaggerated data of 4.3 meters.
In terms of the length of the carriage, it has increased from the current 12 meters to 34 meters, nearly three times. From a plane perspective, the area of the carriage alone is at least about seven times that of the current narrow-gauge carriages. But what about the height?
A carriage with a width of 4.3 meters and a height of 5 meters is not too much, so the height must be at least about 2 meters higher than the current carriage, which is equivalent to adding another layer to the current carriage space.
If calculated in this way, the volume of a single carriage of a heavy-duty locomotive is at least twelve times that of the current carriage, which means that the carrying capacity has increased by more than ten times.
If the Han tribe can really build such a steam locomotive, it will be considered a real land fleet. The carrying capacity of a carriage is stronger than that of a small two-masted sailing ship.
Dashu was shocked by the future described by Luo Chong at this time, and Luo Chong was thinking about how to build a high-speed railway in this world.
High-speed railway, referred to as high-speed railway, does not specifically refer to the modern electric-driven bullet train. In fact, it is just the literal meaning, a very fast train.
During the Second World War in the previous life, steam locomotives were popular at that time, and it was also the peak period of steam locomotive technology. This period was a dividing line for train technology.
After the Second World War, all countries began to promote diesel locomotives, that is, oil-burning trains, and steam locomotives began to be completely eliminated. Therefore, the Second World War was the most powerful time for steam locomotives.
At that time, there were only a few representative models of steam locomotives in the world.
Among them, the one with the strongest carrying capacity is the American "Big Boy" steam locomotive. The front of this train has two sets of cylinders and more than a dozen power wheels. The power is very strong. Although it does not run very fast, it can carry more than 60 carriages at a time. The strong carrying capacity is abnormal.
In addition, in terms of speed, the representative of high-speed locomotives in the West at that time was the Wild Duck steam locomotive developed by the United Kingdom. This is a steam locomotive with a streamlined low-resistance design on the front. It has been mounted with six carriages and ran on a straight plain. The speed has reached an ultra-high speed of 200 kilometers per hour. Even compared with the current high-speed rail, the speed is not inferior.
And for well-known reasons, the bald man at that time did not have the ability to manufacture steam locomotives by himself, so naturally there was no masterpiece to show off.
In that era, the only high-speed train on the land of China was the Asia train built by the Japanese in the puppet state of Manchukuo.
This is also a round head, streamlined low-resistance front, usually equipped with six luxury carriages, with a maximum speed of 130 kilometers per hour, an operating speed of 80 kilometers per hour, and an average speed of 100 kilometers per hour.
To be honest, this speed is not slow for a steam-powered train. The modern green-skinned trains that have not been eliminated, that is, diesel locomotives that burn oil, can only run at this speed at most.
The first high-speed railway built in New China was the Beijing-Tianjin Line. This is not a very long railway that goes directly to the capital, and the route geology is not complicated.
Why was the first high-speed railway built here? Two words, card face!
After all, the capital is here, where else can it be built beside the capital?
What Luo Chong was thinking at this time was how to create such a card face in the capital of the Han tribe. This was not because he was arrogant or whimsical, but because the conditions here in the capital were too suitable.
The area between Takumi County and the capital city is all flood-impacted plains, with flat land, no rocky mountains, and a single and stable geological structure. From the technical perspective of road construction, this is simply the most suitable place to build a high-speed railway.
In terms of politics, this is not only the most important seaport controlled by the Han tribe, but also a direct route from an important port city in the south to the capital city. It would be a pity if the Han tribe did not build a stunning and world-beating facade for such a place.
From an economic perspective, there are more benefits. Not to mention industry, just allowing the people of the capital city to eat freshly caught seafood every day is a very important economic benefit. It can drive many fisheries, feed many fishermen and shipyards.
Finally, from a technical perspective, the first is the design index. The legendary Wild Duck, which can run 200 yards, is only a standard gauge locomotive, and it only has six carriages.
The Asia locomotive built by the Japanese is also a standard gauge with six carriages, which can run at a speed of 130 kilometers per hour.
Luo Chong's goal was not high. As long as his heavy-duty locomotive could run at a speed of 100 kilometers per hour on the flat land between Takumi County and the capital with 20 carriages, it would be fine.
If it could be built, the railway journey from Takumi County to the capital could be shortened to less than four hours, which is about four times the current speed. What a big leap!
And it is not particularly difficult to do this.
Luo Chong carefully analyzed the technology. Whether it is the British Wild Duck or the Japanese Asia, they have three common characteristics.
First, the streamlined low-resistance front shape is the most effective way to reduce resistance and increase speed. Luo Chong can refer to the design of modern high-speed rail bullet heads. It is not a problem.
Second, the fully enclosed locomotive shell, and there must be at least two chimneys.
The fully enclosed locomotive shell is designed to maintain the overall streamline or to reduce resistance. This is not a problem. A few sheet metal workers can get it done with hammers.
The need for at least two chimneys is to discharge exhaust gas faster so that the steam engine can maintain sufficient power, which is not a problem.
The third thing is that the locomotive must have at least three or even four pairs of power wheels, and the size of the power wheels must be at least two meters in diameter, so that sufficient power can be provided for the locomotive.
Think about it, if the cylinder reciprocates at the same speed and rotates at the same speed, the larger the circumference of the wheel, the faster it will run!
However, in order to drive such a large-sized power wheel to rotate rapidly, the size of the cylinder must be large enough. The large-diameter cylinder can provide huge torque and can pull it. In contrast, the shorter the cylinder, the shorter the stroke, so that it can run fast.
With such a cylinder that can pull and run fast, plus a power wheel of more than two meters, and a bullet train shell on the outside, that is, a fairing used to reduce air resistance, it is impossible to make such a locomotive run slowly! ! !
At this time, Dashu suddenly asked, "Chief, since our tribe can now build a bigger train, why don't we just do it in one go? It still feels a bit wasteful to build and demolish it, and then rebuild it again.
"The most important thing is that it wastes time and transportation capacity. Obviously, there is a stronger transportation capacity, why not just build it all at once?"
Luo Chong came back to his senses after hearing this question, sighed and couldn't help complaining, 'Do you think I don't want to build a heavy-duty railway directly? The key is that we can't get heavy-duty rails now!'
He took a deep breath and explained.
"Heavy-duty railway is good, I also want to build it in one go, but it is a bit difficult now. We now have the ability to manufacture heavy-duty locomotives and the ability to roll enough rails, but we don't have qualified steel now!"
He paused and continued, "In fact, a long time ago, when I first started to lead people to study trains and rails, I proposed the idea of heavy-duty railway. At that time, this narrow-gauge railway was not intended to be promoted in the tribe. It was originally intended to be used for mining in mines.
"Later, when we were experimenting, we found that the existing carbon steel rails of the Han tribe could not bear the weight of the heavy-loaded locomotive. We had to use harder manganese steel to roll the heavy-loaded rails. And ferromanganese ore can only be used to smelt manganese steel. It just so happens that this kind of ferromanganese ore is only available in the Tang tribe. So, do you understand now?"
Dashu suddenly realized that the existing resources of the Han tribe could not produce qualified rails, and the Tang tribe had not yet been incorporated into the Han tribe. The Han tribe could not mine that special iron ore on a large scale for smelting, which led to the failure of the leader's heavy-loaded locomotive plan.
But now it is different. More than two months ago, the Tang tribe was incorporated into the Han tribe through a referendum. Now it is also a part of the Han tribe. Similarly, all the resources in the territory of the Tang tribe have become objects that the leader can dispose of at will.
But now he can understand Luo Chong's difficulties. The capital city has slowed down the progress of the project due to insufficient materials, and it will take a lot of time to build infrastructure to turn the ferromanganese ore of the Tang tribe into qualified rails. This is not something that can be developed immediately.
Therefore, instead of waiting there for heavy-duty rails, it is better to lay a narrow-gauge rail first to solve the transportation problem of construction materials for the capital.
Thinking of this, Dashu nodded in understanding, and asked with concern, "Then, Chief, have you arranged everything about the steel smelting in the Tang tribe?"
Luo Chong nodded affirmatively, "Of course, I set the capital in the south, so I naturally have to drive the industry in the south. There is no shortage of iron ore in the south, but if you want to smelt iron, you must have coke. Fortunately, You Fu found a coal mine slightly north of the Tang tribe last year.
"Now as long as we can find a way to open up the road transportation line between the coal mine and the Taigang County iron mine, our southern steel mill can be built immediately. By then, no matter what we want to make, it will no longer be a difficult task. "
Da Shu was relieved after hearing this. As long as the leader had made arrangements, it would be fine. However, when it comes to the overall situation of the entire Han tribe, it seems that no one can see it more comprehensively than the leader.
Especially how to better allocate various resources, who in the world can know better than the leader?!
After talking about the relevant situation of the train, the two talked about the situation in the entire south.
Although Da Shu was nominally only the county governor of Takumi County, in fact, the entire south was under his control or influence. After all, Takumi County was the base of the Han tribe in the south, and all other territories were developed from this base.
The endeavor-type small train was running hard on the rails. Luo Chong and Da Shu looked out of the window from time to time. Large tracts of plains passed quickly in front of them. Looking at these fertile plains that had not yet been developed by humans, the two naturally turned the topic to agriculture. After all, no matter how strong the current industrial strength of the Han tribe is, it cannot cover up the fact that this is an agricultural tribe.
"Chief, this summer, several engineering vehicles were sent from the north, including tractors, excavators and loaders. But I heard from the accompanying technicians that the chief also made mechanical vehicles that can automatically cultivate and harvest crops.
"Now we have the most suitable climate for growing crops in the south. The winter is only about two months a year, and the winter is relatively warm. We may not see the next snow for several years. If we grow crops, it is easy to achieve three harvests a year.
"It's a pity that there are so many fertile lands and a climate suitable for farming in the south, but there are not enough people to develop them. If the chief can approve some automatic agricultural machinery, we can cultivate more land in the south."
When Luo Chong heard this, he seemed to suddenly remember something and couldn't help interrupting.
"No, Dashu, you still have to remember that although the development of our Han tribe requires sharp machinery, it is still people-oriented. Only by doing everything possible to increase the population can we develop and grow.
"Without population, where can we get so many people to engage in industrial production? Without population, how can we provide enough food for the industrial population? Without population, who will operate those complex machines?
" "So, in the final analysis, developing population is our first task."
After a pause, Luo Chong asked again, "I heard that last year, the capital city recruited a group of savages who migrated from the east. They were called the Youqiao tribe. There seemed to be about 700 people, and they were separated from a tribe of 10,000 people. Has this Youqiao tribe been brought here now? "
Da Shu was furious when he heard this. He could not help but complain in his heart, wondering how he had forgotten the chief's hobby. No one who was discovered by the chief could escape. There was no other way except to join the Han tribe.
However, it was not Da Shu who recruited You Qiao, but You Zhi from the capital, so he was not particularly clear about this matter.
Fortunately, there was a station leading to You Qiao ahead. If the chief wanted to know about You Qiao's situation, he could just stop there and ask.
