At this time, Cheng Dong, who was mixed in the crowd of onlookers looking at the map, heard someone call him, suddenly woke up from his contemplation, looked up at everyone and said:

"Oh? Well, let's talk about the railway rolling stock first, I guess you've all seen those two steam locomotives parked on a section of railroad tracks in the cave, right? Because it is very different from the steam locomotives I usually see, I heard that many people are very curious and have climbed on it to play.

It was a Stephenson 0-4-0C tank-style light steam locomotive, two-axle, standard gauge. This is a short-distance light steam locomotive originally used for port and factory transportation, and can be used to burn coal and wood.

This kind of locomotive has a small weight, and it is quite simple, even the cab is semi-enclosed, and in the middle and late nineteenth century, many European countries used it.

In the Old World, such locomotives were probably only found in museums, so I seriously suspect that this locomotive was a copy of Anna when she passed by a railway museum, including the four convertible wagons.

So it's normal that you haven't seen it, and I've only seen it on the pictures in the museum, and there is no doubt that this is an antique-level light steam locomotive. Of course, although the vehicle is very old, it also has outstanding advantages - it is simple to maintain and maintain, it is also very durable, and the most important thing is that the boiler of the locomotive is not picky, and it can be used to burn and split wood.

Of course, there are also disadvantages, because this kind of water tank locomotive has neither a special feeding machine, nor a special coal water truck, so the work of shoveling coal boilers is very hard, and the endurance is also average, running less than 100 kilometers to add fuel and water to the silo and water tank, so, driving this kind of locomotive is actually very hard work.

Obviously, this work must have been undertaken by myself, and what I mean by this is that don't think that I will be very windy when I do this work, but in fact, I will be tired of driving this kind of locomotive for a day, and I have not yet been replaced, so you must send me an assistant. ”

The onlookers only laughed when they heard this, and said one after another, they don't know who will be tired into a dog by then, let's talk about it......

So Cheng Dong continued:

"Speaking of driving locomotives, please rest assured, although this car is an antique, but as a technician who repairs diesel locomotives and steam locomotives, I can drive all kinds of steam locomotives, this is not my bragging, after all, for more than a hundred years, the principle and structure of steam locomotives have not been far from there......"

When Cheng Dong said this, he took out another piece of paper from his body, which was obviously a list, and after glancing at it, he said:

"Also, because Anna provided us with a nine-kilogram light rail, the wagons were also light, and although the gauge of this railway was European standard, the carrying capacity was not large, and the standard load of a wagon was only about fifteen tons, and the carrying capacity was very, very limited.

At present, we have a total of four wagons, and the maximum load capacity of each wagon can exceed about 20% of the standard load, that is, about 18 tons.

OK, that's the basics.

Oh! In addition, the reason why I asked Anna to provide 100 kilometers of light rail laying materials in the first place was because Cao Limei and I had calculated the mileage of the railway from the Red Mansion to the major mining areas of the island, based on the mineral resource distribution map drawn by Xiao Cao, of course.

Now, judging from the map, if Cao Limei's chemical base site selection is approved by everyone, then it can also save a lot of valuable railway mileage, after all, the mineral resources in that area are relatively concentrated. ”

"Chengdong, how are you going to build a railway? Is there a construction plan? ”

At this time, Teacher Zhao asked.

"Well, there's ......"

Cheng Dong glanced up at the people around him, and after a moment of silence, he continued:

"The initial plan is as follows: the starting point of the railway is calculated from the exit of the cave and extends southeast to the Red Wharf. This is the first phase of the project, and because of the gentle terrain, this section of the road is relatively easy to repair.

The second phase of the project starts from the Red Wharf and turns northeast to reach the pyrite and lignite mining areas in the upper reaches of the Xiliu River. ”

Cheng Dong pointed to the map in front of Cao Limei and said.

"It's just that the terrain for this mileage is a little undulating, mainly to cross some upstream rivers, because we don't have the materials to build the bridge at the moment, so we have to make some small bends."

"Don't we have reinforced concrete?"

Someone chimed in.

"Those reinforced concrete seem to be dedicated to the Moon River Dam, do we really want to embezzle them?"

Someone in the crowd responded.

"It depends, the supplies Anna gave are all the ...... of the margin"

“…… So, I'm going to try to build bridges without those precious reinforced concrete, and from the map, just make a few slow bends if necessary. ”

After Cheng Dong finished explaining, he continued to point to the map and said:

“…… The railway is built near the pyrite site and then turned to the northwest, along the west bank of the main stream of the Xiliu River to the chemical base at the mouth of the river, but in the meantime a bridge must be built across the east-west tributary, and I plan to build a bridge with stones, or if I can, with the steel buildings that Anna helped in the cave and use scaffolding, of course this is temporary, and later it will be changed to reinforced concrete when possible. Brother Hou, what do you think? ”

Cheng Dong said this, raised his head and asked Hou Xianglin in the crowd, and the latter looked at the map, supported his chin with one hand, thought about it and responded:

"Well, with locomotives, wagons and loads, a five-car train is about 100 tons, right? In this way, as long as you are not overweight, you should be fine. ”

"OK, the second phase of the project is now complete.

Then the third phase of the project will follow, and the railway will follow the coastline westward, to the limestone mining area and the coal mining area.

During this period, it is estimated that several branch lines will be built to connect coal mines, limestone quarries and other places. Then, through the coal mine, it goes around back to the pyrite point in the upper reaches of the Xiliu River, forming a small loop in the industrial area, and I have carefully calculated that this direction and layout is not only the most economical material, but also conducive to the internal circulation and transportation of the entire industrial area.

This is my plan for the construction of the railway, and roughly calculated, the total mileage of these three sections of the railway is about 60 kilometers.

After the completion of this railway, it helped us a lot in the initial industrial transportation, and if it was supplemented by a few small branch lines, the raw materials needed for industrial construction, especially the transportation of ore, were basically solved.

Of course, if there is no construction machinery in the cave, loading and unloading ore wagons is a heavy physical work, so we still need to bring in labor as soon as possible, especially before our oil and construction machinery are exhausted.

Well, the topic is not far away, here about the railway mileage data to explain, because the field measurement before the crossing is only an approximation, the specific mileage may have some discrepancies, but the discrepancies will not be very large.

In addition, the topography of this island is high in the middle and low on both sides, and there is an obvious uplift of the highland that runs through the whole island, but the overall terrain is very gentle, so it is more advantageous for building the railway, the overall undulating slope of the railway is not large, and the average slope can be kept below three degrees, so if a single machine pulls four wagons, the speed of full load can reach more than 30 to kilometers per hour......

"Brother Cheng, is it worth extending the railway there for the sake of those small number of chicken nest mines?"

Someone in the crowd asked.

"It should be worth it, because those chicken nest mines have enough reserves for us to dig for twenty years! And it is our industrial zone, and there will be a lot of industrial construction along the line in the future. ”

Cao Limei responded immediately.

"Are there so many reserves?"

"According to the current scale of coal and coke chemical production of Mr. Zhao, it's about the same......"

"Ladies and gentlemen, what are your opinions on the railway construction plan in Chengdong?"

At this time, Mr. Zhao also nodded, obviously he basically agreed with Cheng Dong's plan, but he still asked everyone.

"Well, it feels good......"

"If you want me to say, isn't that ......?"

……

In addition to the construction of the railway, Hou Xianglin also proposed a highway construction plan, Mr. Zhao also proposed the specific location of the glass factory, and Huali They also suggested that after the railway is repaired, the pyrite boiling furnace and iron-smelting cupola furnace in the karst cave should be transported to the ore site in the upper reaches of the Xiliu River as soon as possible, and the chemical metallurgy can be produced cooperatively.

Then Hou Xianglin put forward a proposal to build a storage area at the Red Wharf. In short, the crowd on Cao Limei's side discussed the future industrial construction plan more and more deeply......
