Steel steam and flame

Cassia jumped off the locomotive and found Puno waving to him in the distance with cleaning tools. She must have heard the sound of herself hitting the steel plate with a stone just now, Cassia thought.

"What happened?" Puno came over and asked, his eyes also on the fronts of the cars in front of him. "They are all scrap metal. Apart from turning into a pile of rust, there seems to be no other result."

"Maybe that's it." Cassia said back to Puno, who was standing next to him. "This locomotive is completely scrapped, and most of the useful things have been dismantled by the army. I don't know what's in the other locomotives." Whatever the situation is, I hope it won’t all look the same.” If so, he could only carry his luggage along the railway line and rush to the battle line on two legs. It is definitely possible to get there, but it will take more experience and time on the way.

"I want to use the tools here. If there are still usable parts in these locomotives, I also want to move them and reassemble a locomotive." Cassia asked Puno, "I have learned a little bit about the basics of machinery before. Simple The structure is still very easy to use.”

Puno probably just thought that Cassia had nothing to do when she stayed here, and simply didn't want to be idle: "There is no problem. It is rare for there to be any problems at this station. Even if there are, it is always done by people from the army. . The tools are very complete and were left behind by the army when they came here. It doesn’t matter if they are broken, they won’t care about these things.”

There was a room that served as a tool room, at the end of a row of houses, and it smelled like lubricants. The tools are all coated with a layer of oil to prevent rust and are well maintained. This is one of the few things you can do in Puno at this station.

There was also a welding and cutting machine inside, and several cans of fuel were placed there in steel cans, which was exactly what Cassia wanted to see. Instead of moving all these things out, he first checked the conditions of the other heads. To recreate a complete operational steam turbine, not only are the various tools and materials insufficient, but Cassia currently does not have such strength.

I have seen many types of driver structure diagrams in books, and they were all the focus of school exams. If he has paper and pen on hand, Cassia can even draw the entire rough drawing now. But there is a huge difference between knowing and being able to do it.

The other heads are in a similar situation. Most of the usable things have been dismantled. The only ones left are copper pipes and valves. Almost all the steam hoses are damaged, which cannot be used for a long time.

The final results were disappointing. The army seemed to be in short supply of these items. Any parts of any value had been cut away, leaving nothing but a pile of useless steel pieces. He had a burning desire to recreate a locomotive that could run on steam, and he was very interested in these things. But under the unsatisfactory power structure, the hot mood quickly cooled down.

In the end, the welding and cutting machine could only be dragged out, and Cassia began to cut the parts that he could use, including several pairs of smaller steel wheels and bearings that looked newer. A steel plate with an area that can accommodate your own luggage is directly used from the armored steel plate on the locomotive. First cut off a piece as a whole. Because of the ceramic piece in the middle, the two incompletely bonded steel plates can be easily separated without spending much time. Among them, all Cassia needs to do is to hit them hard with big rocks.

When Puno heard the loud noise and rushed over again, the weeds were already filled with scattered things. At this time, Cassia was still using a cutting machine to cut what he wanted from the locomotive, which was also the most important core component of the alternative plan. A shaft with sufficient shape and strength to be used for many years was used to convert power transmission. way stuff.

"Is there something urgent that you need to rush over?" Puno came over and asked.

Cassia had just finished cutting the shaft, and it fell heavily on the rails with a "bang". At this time, Puno walked over and pulled the dozens of kilograms out from under the train.

"Thank you." Cassia turned off the cutting machine and jumped off the front of the car. "It's not an urgent matter, but I can't stay here and wait for the rearrangements and troops who don't know when they will come, so I still have to do it myself. Something you can do.”

"Let me help you. I have seen the human-powered rail car many times and I remember the general structure. I can help you a little." Puno said. When he saw the axle piece he dragged out, he already knew what Cassia wanted. Something is coming, "But to talk about something bad, I don't know exactly what the situation is at the front, although I have been there several times before. But maybe I am really afraid of how it will affect our lives. From here to the front line, the isolated area in the middle is really big, not in a symbolic sense. You have to take the army train to go there, but it also takes half a day each time. The speed of those trains is not as fast as the high-speed train, but it is still It won’t fall much. If you rely on manpower, no matter how much you reduce the weight, there will be no advantage in speed or physical strength. It will take a very long time to get there.”

Cassia grinned and said it was okay. Of course Puno didn't know about the surgery. From an ordinary person's point of view, the facts are exactly as he said, physical strength and speed do not have any advantage. And we still have to go deep into the railway lines in the mountains. Perhaps because of the battle line, we have to make several circles in some places.

But in terms of physical strength, Cassia is not worried, and the speed can also be solved well due to the strength of the surgeon. But none of this can be told to Puno. All words can only be replaced by "It doesn't matter."

After the parts are prepared, the subsequent assembly is relatively simple. Both of them understood the mechanical principle and structure, but it still took a lot of effort to actually implement it. The connection parts are directly welded, without any carelessness, and it is an effective method. The intensity is completely appropriate. Cassia believes that as long as she controls her strength carefully, there will be no problems halfway. The total area of ​​these steel components is only three or four square meters. Compared with the locomotive next to it, there is no significance in competing with each other.

It was basically completed in the afternoon, which took longer than Cassia imagined. After that, there will be some simple optimization and trial operation work. Lubricating oil, structure for fixing luggage, strength inspection of welding parts, small iron frame for placing lamps, and weight reduction of the entire human-powered rail car. Where high strength is not required, cut off the steel plates and replace them with wooden boards. On the basis of not destroying the complete structure, whether it is drilling holes or cutting off a few pieces according to the distance on the steel plate, it is all specific work during optimization.
