Chapter 933 Witnessing the History of the Han Tribe
Luo Chong and You Fu discussed the starting point for the next exploration, and the people around them naturally heard it, and the people present immediately understood it. It did
n’t matter to them whether to explore or not. The important thing was that they heard a message from this news, that is, the relationship between the Tang tribe and the Han tribe had changed.
The Han tribe was going to create a second steel smelting center in the south based on the iron ore of the Tang tribe.
This news meant that their leader had reached some kind of agreement with the Tang tribe, and the two tribes would definitely merge in the future. Moreover, Tang Yao was right next to Luo Chong now, and Luo Chong dared to say in front of her that it was naturally impossible for the two tribes to fight.
This meant that the merger must be peaceful, and given the gap in strength between the two tribes, there was only one result, the Tang tribe would be incorporated into the Han tribe as a whole, and eventually become a part of the Han tribe.
This was a good thing!
You have to know that although the population of the Tang tribe is a little smaller, the territory is not small. There are eight counties, which is not smaller than the eight counties in the north. And to be honest, the last census of the Tang tribe showed that there were more than 80,000 people. Although it is a little less than Qiongzhou Island, in this era, there is no other tribe that can compare with the Han tribe, okay!
Without consuming a single soldier, nor consuming money and food, at most supporting a wave of construction, at such a price, you can peacefully exchange the territory of eight counties, and there are 80,000 people. How to think about it is a good deal!
The Han tribe is really getting stronger and stronger under the leadership of the leader!
After everyone sighed, their minds returned to the train they were riding.
Now that the Han tribe has this train again, where can they not go in the world in the future? !
Woo woo woo woo————
The locomotive roared, pulling the long dragon of carriages weighing tens of thousands of tons, rumbling forward.
After 20 minutes of driving, Luo Chong and his friends had already seen the leader's personal guard cavalry who had rushed to the front at the beginning outside the window.
The guards rode their war horses and led the way. When they started, they left the train far behind, and even the dust raised by their horses' hooves could not catch up.
But now, twenty minutes have passed. Even the war horses have exhausted their physical strength after running so fast for such a long time. They can only move forward slowly. If they are urged to continue running wildly, they may be exhausted to death.
The train that Luo Chong and his men were riding on was carrying so many things, but it was still moving leisurely at a speed of more than 20 kilometers per hour. It was indeed not running very fast, but this long iron dragon did not show any sign of fatigue, as if it could run forever as long as it was given enough coal and water.
Of course, running forever is impossible, because the railway is only more than 100 kilometers long. No matter how powerful it is, it has to stop at the station!
An hour passed, and the train was still moving forward leisurely. Although everyone was no longer as surprised as at the beginning, they had to admit that this thing was really a magical tool. Even if it was a horse-drawn carriage, the horse would have to rest after running for so long, but this piece of iron didn't need it at all.
In the cab at the front of the train, the driver was operating the train.
In fact, there was nothing easy to operate the train. This thing didn't have a steering wheel at all, and it wouldn't let you turn. It would run along the rails by itself. The only use of the driver was to keep an eye on the railway ahead to make sure there were no obstacles.
For example, just now the driver encountered a group of wild antelopes crossing the railway. After he saw it from a distance, he quickly blew the whistle. The whistle blew and scared the antelopes away immediately.
In addition, keep an eye on the railway section and adjust the speed from time to time. If it is a long straight line, put the steam valve to the maximum, use the maximum power output, and let the train accelerate again and again. If you see a fast curve, quickly close the steam valve, slow down the train, pass the curve at a low speed, and then speed up after passing the curve to avoid high-speed curves directly running off the track or overturning.
The co-pilot next to him was filling coal into the boiler with a shovel. As for adding water, it is added through metal pipes and valves.
Moreover, the boiler is not added directly. If cold water is added directly to the boiler, the core temperature of the boiler will be rapidly reduced in a short time. Once the temperature drops too fast, the output power of the steam locomotive will drop sharply at the least. In severe cases, the steam pressure in the boiler will be rapidly reduced due to thermal expansion and contraction, and even a negative pressure state will be formed. In severe cases, the boiler will shrink inward due to the principle of exhaust, or even explode directly!
This is a very dangerous thing, so water must be preheated before adding it to the boiler!
First, the cold water is transported through the pipeline to the middle of the superheating pipe, smoke pipe, and steam pipe in front, and the heat emitted by these pipes is used to preheat the water in the water supply pipe. After preheating for a certain period of time, when it reaches 70 or 80 degrees, it is added to the boiler.
At this time, since the new water has a very high temperature, after being added to the water tank in the boiler, it is heated again by the boiling water and steam in the boiler. It basically boils in less than a minute, and becomes steam and superheated steam again, entering the cylinder to push the piston to do work and convert into power.
The boiler of the Endeavour locomotive is not large and has limited power, so don't expect to run very fast, but small has its advantages. With such a locomotive, the coal and water truck behind the cab can carry one ton of coal.
These two thousand kilograms of coal are enough to support the Endeavour to run 500 kilometers with a full load, which is equivalent to consuming 400 kilograms of coal per 100 kilometers.
400 kilograms of coal is really not much, that is, the kind of fish scale woven bags used to hold feed, which only fill four bags.
Four bags of coal blocks are not much at all to carry tens of thousands of tons of goods for 100 kilometers!
Of course, compared with the internal combustion engine with higher thermal efficiency, this loss is still too great. The heat energy conversion ratio of the steam engine is only 10% at most, and the Endeavour of the Han tribe cannot even reach 10% because it does not have an advanced control system.
A better gasoline engine can achieve a heat energy conversion ratio of 42-3%, which is already the most advanced engine currently used by humans.
The difference between the two lies in internal combustion and external combustion. The internal combustion engine sprays fuel into the cylinder, ignites the fuel in the cylinder, and uses the flame to expand the gas to directly push the piston to do work.
For the steam engine, its combustion chamber and cylinder are separate. The heat energy must be converted into steam in the combustion chamber outside, and then the steam is used to push the cylinder piston to do work, which adds an extra layer of heat energy loss. The steam also releases heat during conduction, and all this heat energy is wasted.
However, even the steam engine is now the best power machine of the Han tribe. Even if there is an internal combustion engine car, it is very difficult for the Han tribe to support such a large amount of oil consumption.
What's more, what's more————
The train's wheels rolled over the joints of the rails, making a constant clanging noise, but everyone has now become accustomed to this feeling.
Two hours passed, and at ten o'clock in the morning, everyone in the car began to feel a little bored, mainly because there was nothing to do in the car, and they didn't bring any toys for entertainment. At this time, the thing in Luo Chong's hand became the object of everyone's envy.
Tang Yao took out an exquisite wooden box, which was filled with black and white ceramic chess pieces. Tang Yao directly unfolded the box, and the surface of the box became a chessboard.
She and Luo Chong put the box on their legs and actually played Gobang. Everyone was stunned and regretted why they didn't bring a chessboard.
This was something Luo Chong specifically told Tang Yao to bring. After all, among the people present, only Luo Chong had taken a long-distance train. There were no mobile phones in this era. In a closed carriage, there were only a few people. What to do for entertainment for eight hours? !
Luo Chong and Tang Yao played a few games, and seeing several county governors standing beside them and watching eagerly, they felt sorry, so they gave instructions to Lin Fei.
"Lin Fei, go to the dining car at the back and ask them to prepare some tea, cakes, or fruits for everyone. If that doesn't work, you can get some peanuts for everyone to eat."
"Hey, that's good, it would be great if there were fried peanuts with shells. I love that!" Yun Zhi was also happy when he heard it. Getting some peanuts to peel and play with is also a kind of fun, isn't it? It's better than being bored and dazed here.
Lin Fei responded, and directly from the outside of the rear door of the carriage, grabbed the railing outside, and stepped into the door of the dining car at the back. If you don't know, you might think he was a car-stealing gang of the Railway Guerrillas!
This was also a mistake in the original design, or it can't be considered a mistake.
Because the Han tribe didn't even have a proper passenger carriage, all of them were passenger and freight carriages. The carriages were bare, with only one seat at most, so how could they be equipped with so many other ancillary facilities!
Therefore, there were neither toilets nor connecting passages between these carriages. It was impossible to get from one carriage to another. One could only cross the railing on the outer wall of the carriage to the door of another carriage, which looked like an acrobatic performance. Fortunately,
the speed of this train was not fast, so it was not too dangerous. Moreover, when it was used to transport passengers, passengers were not allowed to run back and forth between several carriages.
Not long after, Lin Fei brought a wooden food box from the dining car. The food box had eight layers, and it was a large food box. The bottom layer contained tea bowls and tea leaves, and the upper layers were filled with peanuts, fried soybeans, and even dried meat, candied fruit, dried persimmons and other dry snacks.
When everyone saw it, they immediately divided it up. Luo Chong only asked for a cup of tea and nothing else.
After everyone had divided it up, Lin Fei stood at the rear door of the carriage again, holding the railing next to the door with one hand. He shouted to the back, and a cook immediately appeared at the door of the dining car behind.
The guy stood at the front door of the dining car in the same posture, holding the railing with one hand and holding a large iron teapot with the other hand, and then handed it directly to Lin Fei. The two of them, like members of the railway guerrillas, completed the handover of the hot water kettle outside the train car.
Damn, it's too difficult to drink hot water.
After their car was replenished with hot water and snacks, Lin Fei used the same method to pass some hot water and snacks to the two cars in front.
The journey was safe and smooth. At noon, that is, at twelve o'clock, the train had traveled nearly half of the distance, but everyone was already hungry at this time, and it was time to eat again.
There was no other way, Lin Fei had to use the method of riding the train to deliver meals to the three passenger cars one by one. Finally, when he was done and everyone was eating together, Lin Fei gave Luo Chong a suggestion.
"Chief, this is too troublesome. Let's not talk about whether it's tiring or dangerous, but this operation is really too troublesome. I think this passenger and cargo carriage needs to be improved. A double door should be opened on the front and rear carriage walls. Even if people can't pass through, it will be convenient to pass things between the
front and rear carriages. If you are worried about the two rows of seats on the front and rear carriage walls, then you can open two windows on the front and rear carriage walls, as long as people can stand in the carriage and pass things back and forth.
Oh, by the way, if you open windows, I suggest opening horizontal sliding windows from left to right, so that the windows don't sway and it's easy for the windows of the front and rear carriages to collide."
"Well, this suggestion is very good. You can do it yourself. You don't need to ask for my opinion on such a small matter. Isn't this a trial run? That is to find problems during the trial run and then make modifications again.
The train has not been put into service in large quantities yet. Even the current one is just a large-scale experimental product. Find problems as early as possible and improve them as early as possible so that they can be finalized as soon as possible. When it comes to mass production, it will be difficult to make improvements."
Luo Chong nodded and agreed with Lin Fei's suggestion, and then reminded him again.
After everyone had lunch, someone wanted to go to the toilet. The front carriage was fine. There were all men. Many people stood at the door of the carriage and urinated outside. There was no need to be embarrassed. Anyway, it was a large field outside and there was no shadow of a person.
But there was a woman named Tang Yao in Luo Chong's carriage, and she was the leader's woman. How could they dare to do it? So they could only hold it in. If they couldn't hold it in, they would jump on the train and run to the front carriage to relieve themselves, calling it "visiting".
It was not until 1:30 pm that the train finally passed the first intermediate station of this trip, which was the temporary railway station in Yize County. However, the driver had no intention of stopping the train because the test this time was about the driving speed. If the train stopped at this time, how could it measure the fastest speed?
However, the people of Yize County knew roughly the time when the train would pass through their station. Calculating that the time was almost up, the people ran to the railway line with their families to see the "big train".
Seeing the train whirring and spewing steam and billowing white smoke, rushing all the way to them, the local people immediately cheered on both sides of the railway. Another artifact of the Han tribe was born.
The driver hurriedly blew the whistle, first to warn the people not to block the railway track, and second to blow the whistle to salute the people along the line.
In the three passenger carriages at the rear of the train, Luo Chong and a group of elites from the Han tribe also stood at the door of the carriage and waved to the people below. Luo Chong stood directly at the door of the carriage, while others were at the back door, and some directly leaned half of their bodies out of the window and waved to the people.
Among the people below, a photographer held up a camera to take pictures of this exciting scene, witnessing a historical moment.
In the carriage where Luo Chong was, Ao Fei, the founder of the camera, also personally took a picture of Luo Chong waving to the people. This was the first time that the leader took the train developed by the Han tribe and waved to the people along the way.
This is a big chapter!!!
