"Okay, now tell me how to change this track?" Bao Bao argued with Xie Mingfang quite unconvinced, "Now that we have laid more than twenty kilometers of this track, you are telling me now that you want to change the track, how should I change it?" ”

Sun Qiu Qiu Ke's situation was sealed after the cold battle

Xie Mingfang did not give in at all, "Now it is only twenty kilometers long, which already reflects this kind of problem, now we don't replace this kind of track, do we have to wait until thousands of kilometers are laid in the future to change the track nationwide?" Now if you don't take advantage of the lack of orbital mileage to replace it quickly, and wait until there is a big problem in the future, the cost is not something that can be calculated as it is now. Pinshu mobile terminal "

"And what do you mean by switching to broad gauge?" Bao Bao asked a little depressed, "There is not much difference between the weight of the broad gauge and the narrow gauge transportation, and the narrow gauge is much smaller because the vehicle is smaller, the steering space is much smaller, and the cost is much lower than the broad gauge. If I were to say that it would be better to keep the narrow gauge now, we can only pull so many things by the vehicles we transport. ”

The two leaders of the construction department in the construction office are arguing over the track of the railway at the moment, the track width has always been a difficult thing to choose, even in the old world is standardized at every turn, there are several different track standards, the narrowest type such as the Cape gauge of 1067 mm, is the standard narrow gauge, this kind of track is the first in Norway to put into use, the reason why they choose this narrow gauge is mainly because the mountains in Norway are extended, and the freight volume is not large, The construction of the narrow gauge should occupy less space in the far and wide gauge, and the construction cost should be saved a lot, but because the width of the sleeper used in the narrow gauge is less, the average pressure on the ground is larger, so the pressure on the ground is relatively large, and the weight of the goods loaded by the train is relatively much less.

Now Dongfang Port has laid railways in many places, such as the passenger railway from Yancun Industrial Zone to Dongfang Port West Station and then to Beiqiaotou Town North Station, from Yancun Industrial Zone to Dongfang Port Cargo Transfer Station, from the new old area to Dongfang Port West Station of the veteran special train, and from Guangrong Ling to Beiqiaotou Town North Station and then to Dongfang Port Cargo Transfer Station several railways, the mileage of these railways alone has exceeded 20 kilometers, but the problem is that these tracks actually use a narrow gauge with a width of one meter. In fact, this one-meter-wide narrow gauge was just a 500-meter-long temporary track that Zhang Yuan temporarily laid outside the heavy industry laboratory when he was trying to produce a steam locomotive. By the time Xie Mingfang noticed the problem, the track had already been laid for twenty kilometers.

Zhang Yuan is no wonder about this, in fact, Zhang Yuan still reminded the elders of the construction committee at the beginning that the track was an experimental track laid by himself casually, and if you need to change it, you can tell him that the industrial committee will modify the wheel base of the locomotive. In fact, the Industrial Committee at the beginning of the design of the steam locomotive was designed according to the 1.5 meter wide gauge, both the width of the car body and the length of the car body, which is the most suitable for the 1.5 meter wide gauge, and the Industrial Committee even prepared a modification kit with different gauges at the beginning, which can be replaced in a very short time if it needs to be replaced. But no one paid attention to him in the construction committee, and he tried to remind him a few times, but there was no time when he could find the manager in the office building of the construction committee, so he could only leave a message in the visit record book, but whether it was Xie Mingfang or Baobao, he was so busy every day that no one went to read the visit record book. If it weren't for the fact that Xie Mingfang was going to propose to the Executive Committee a few days ago to build a railway from Dongfang Port to Beihai, when he was looking for a bag to get the information, he happened to see that the track gauge written in the information was one meter, and Xie Mingfang was stunned at that time, and hurriedly ran to the side of the train track, and saw Beiqiaotou Town from Yancun Industrial Zone, and the width of the track was all one meter. Bao Bao himself was also confused, and he copied the construction plan directly from the heavy industry laboratory at that time. At that time, the sleeper production tools used to lay the rails were also specially customized according to the requirements of the heavy industry laboratory at that time, so the production was also matched, and now it was suddenly found that the track was wrong, and the previous sleepers were laid in vain. One kilometer basically requires 1,800 sleepers, so now including the sleepers that have been produced and ready to be used as spare sleepers, a total of more than 20,000 sleepers can only be dismantled and scrapped, which is a heart-wrenching waste for bags.

"Can we keep the track of the Dongfang Port section, but when we go out to lay a new track in the future, can we use a new broad gauge?" Bao Bao said to Xie Mingfang in a consultative tone, but before he could finish speaking, Xie Mingfang interrupted mercilessly, "This is impossible, the most important thing for a unified country is that books are on the same track and on the same track, the ancients thousands of years ago knew this truth, do you want to do the opposite now?" ”

"No, I'm just saying that since these tracks can be used, why don't you use them first, and wait until you need to replace the tracks in the future, and then go to ......" Bao Bao's own words had no confidence, Xie Mingfang shook his head, "This is impossible, if you want to say that you need to replace them in the future, then why keep it?" Wouldn't it be better to replace it now? What do you think it takes for a railway to work? Whether it is traffic signals, towing locomotives, carriages, including sleepers and rails are all needed to be maintained and replaced all year round, your sentence that needs to be replaced in the future is too broad, it is impossible to determine what the specific reason is when it will be replaced, as long as it is maintained, basically a railway does not need to be replaced for hundreds of years, for example, India before we left, their current railway is still built in the British colonial era, and many sections of 60,000 kilometers have even been in operation for more than 150 years. Some of our own railways in Wuhan were even built during the Qing Dynasty, and they have been running for more than 100 years. Although it is uncertain whether a railway like ours will be used in a hundred years, it is certain that many of us will not see the day when this railway fails, and instead of throwing the basin to future generations to solve, why can't we deal with it in the first place? ”

"Uh-" Bao Bao couldn't help but be a little speechless, and hesitated for a while before speaking, "Our existing track is already running, and many sections of the road have a very high traffic flow. Now is the time when we are at odds with the Maidno people, many factories have stopped production, and even then the volume of railway traffic is still quite large, and if we stop the whole railway line to replace the tracks now, then this will certainly not be able to be completed in a month or two, and with the current capacity, it will take at least ten to twelve months to complete the replacement work. As you know, we are now in talks with the Medeno people, so it is possible to revert to the previous situation of full trains in recent months, and if we can't restore rail capacity in the short term, then our production will definitely be affected by traffic conditions, which is unacceptable. ”

"But you also have to think about it," Xie Mingfang said-for-tat, "a railway is running, whether it is a locomotive running in front of the city, or a carriage, it must be always available, even if according to what you said, the Dongfang Port uses narrow gauge, and the railways extending outward outside the city all use broad gauge, so what is the specific meaning?" Can it bring us any benefits? No! "This is the train that we run on these railways, both wagons and coaches, and because of the lack of capacity, the transport department is also ordering several steam locomotives and a large number of carriages from the Industrial Commission to increase the capacity, and they have also applied to us to add a double track parallel to the existing road to ensure maximum efficiency, and now you tell me, what track should be set up on the double line?" Is it also the construction of narrow gauges? ”

"It's definitely not going to be." Of course, Bao Bao knows that since it is necessary to add a double line, it is definitely impossible to lay narrow gauges, so naturally you can only choose broad gauges, and it is impossible for broad gauges and narrow gauges to run at the same time, and you must know that the trains running on this line at the same time must only be the same standard and the same gauge, otherwise it is meaningless to lay double gauges.

"We can do this now, first start laying the broad gauge according to the double line, so that it will not affect the operation of the original narrow gauge," Xie Mingfang said after a little thought, "At the same time as the laying, let the transport department order new broad gauge locomotives and carriages from the industrial committee, and when the double track is laid, the broad gauge will be put into use first." At the same time, all the original lines were closed, and all the narrow-gauge vehicles were returned to the vehicle factory for modification, I remember Zhang Yuan said that he had a batch of modification kits that could be used to replace the rules, if it was feasible, then wait until the double line was laid to quickly replace the rules of these heads and wagons, and at the same time we began to replace the original old lines. After the old line is laid, all the replacement is completed, anyway, the old line is designed according to the standard of broad gauge, only the width of the sleeper needs to be replaced, and the amount of work is now imagined to be low. And can we ask the Industrial Council to build a machine that can lay rails automatically? ”

Bao Bao almost didn't sit on the ground, this first version of the industrial revolution has only just begun, this is thinking about laying rails automatically, "It's not easy, it's too difficult to lay rails automatically, let's let people do it." ”

"You think, now there are fewer and fewer people who can be used in the project, if the number of people who used to lay the old railway was a hundred, now I am afraid that it is only less than forty," Xie Mingfang sighed, "With this original number of people forty percent to do this 100 percent of the work, it will definitely delay the construction period by more than two times, if you can use an automatic rail laying machine, and it is better to have a bridge erecting machine." ”

"Huh?" This long-span bridge erecting machine can pick up a section of reinforced concrete bridge deck that has completed the maintenance period and directly place it on the bridge pier that has been built, and it can be completed in a few hours before it takes hundreds of hours of work. "We can't make this now, can we?" Baobao can't stand Xie Mingfang's divergent thinking now, "We don't have this kind of large-tonnage crane now, and we don't have hydraulic transmission components, and the existing materials can't meet the requirements of the bridge erecting machine." Let's talk about the automatic track laying machine, which basically has a locomotive to push and run. ”

============================= divider =============================

"What? Do you want to build an automatic track laying machine? Zhang Yuan's eyes immediately widened, staring at the bag, and the bag spread out his hands, "If you have any opinions on this matter to tell Yang Minghuan, anyway, she Xie Mingfang is asking for this thing, and it is best to put it into use in a short period of time." ”

"Meow, when I'm Doraemon, right?" Zhang Yuan couldn't help but burst into foul language, "We don't know if there is an automatic track laying machine in our technology library, if not, we have to design it ourselves, not in the past few months, we are tackling the internal combustion engine during this time, if we can't attack it, it will be very troublesome." ”

"Internal combustion engines? Why the hurry? Bao Bao couldn't help but be stunned, and was about to continue asking, but was interrupted by Zhang Yuan, "Don't you want to make trouble with the mobile force?" The Marine Corps is equipped with that kind of amphibious support vehicle, and the Army saw it and complained to me, saying that the Marine Corps is very good to use this kind of vehicle, and the Army wants it too. But the Marine Corps only has six or seven of these cars in total, and they are made with engines brought from the old world, and now the Army is coming to ask for them, so how can I build them for them? Don't have to solve the engine problem first? ”

The enemy is not a ghost, and the ghost is a lonely test feather

"What does the army want amphibious vehicles for?" Bao Bao forgot his intention at this time, and was full of interest in the army's need for amphibious vehicles, and hurriedly asked. Zhang Yuan smiled bitterly, "The army didn't want an amphibious vehicle, but they needed a car with enough off-road ability to transport personnel, and I helped them think of the model, so I chose the German's 82-barrel car, which is light and uses an air-cooled engine, as long as the oil is sufficient, it will not break down." It's just that the conditions are a little worse, and there is no air conditioning. ”

"Uh-" Bao Bao couldn't help but be a little speechless, and hesitated for a while before speaking, "Our existing track is already running, and many sections of the road have a very large traffic flow. Now is the time when we are at odds with the Maidno people, many factories have stopped production, and even then the volume of railway traffic is still quite large, and if we stop the whole railway line to replace the tracks now, then this will certainly not be able to be completed in a month or two, and with the current capacity, it will take at least ten to twelve months to complete the replacement work. As you know, we are now in talks with the Medeno people, so it is possible to revert to the previous situation of full trains in recent months, and if we can't restore rail capacity in the short term, then our production will definitely be affected by traffic conditions, which is unacceptable. ”

"Barrel car?" Baobao's eyes widened, "You mean the round one?" ”

"No," Zhang Yuan said a little speechlessly, "Don't worry about this, I only say so much, it's a leak if I say too much, anyway, the model and everything have been chosen, only the engine is missing." ”

"Not really, right?" The spirit of the good baby of the bag is still possessed, "Cars need rubber tires, and we don't have rubber in our rubber plantations, right?" ”
