Everyone immediately rode with Huo Gang in the direction of the test. Along the way, Huo Gang had already seen the long paved rail on the ground. The steam train was still in the warehouse on the side of the track. Huo Gang was not in a hurry and walked towards the track first.

The track is about one meter higher than the ordinary road surface, but it is actually almost the same as the tracks in later generations. The top is covered with gravel laid by various stone crushers, and then the rails are fixed on the reinforced concrete sleepers and placed in the gravel.

Standing on this track, Huo Gang's spirit was a little dazed, because this track made Huo Gang feel like he had returned to his later generations without traveling. This track was almost no different from that in later generations. Of course, if you don't look at the gap between the rails that are about ten meters away, there would be no difference.

The rails with gaps like this have almost disappeared from all the major railways in later generations. Only on some remote and spare old-fashioned railway lines have such old-fashioned rails.

New railways in later generations have become seamless rails, but these are not important. In this era, even trains were just beginning to be manufactured, and such rails were already sufficiently used, and the speed of trains in this era could not be very fast.

The others followed Huo Gang and stood next to the railway, "How far have you laid such an experimental railway?" Huo Gang took a deep breath, withdrew his thoughts and asked.

"We have laid about 12 kilometers of this track at present. In addition, we have started to build a brand new railway bridge and a new railway planning foundation. The new railway planning has been laid for about 60 kilometers, but the final roadbed has not been laid yet." Wang Luo next to him immediately spoke.

As the most important minister of the Ministry of Construction, Wang Luo must appear here, because the Ministry of Construction is responsible for the construction of the railway.

Without roadbed paving, it means that land leveling and road exploration are carried out. The final roadbed paving is related to the top layer of gravel, which must be laid with the last rail.

"How is the speed of construction?" Huo Gang asked.

"The speed of leveling the land is similar to other roads, but if it is built in the later stage, I feel that it will be much faster than that of ordinary concrete roads." Wang Luo said.

"Oh? Why?" Huo Gang turned around and asked.

"The foundation leveling of roads is the same as the method of concrete roads. It can start from different sections at the same time, and the speed is about the same, but because the railway subgrade and other aspects are at least one meter to two meters higher than the surrounding ground, in order to avoid later waterproofing problems. In this way, the project volume will be larger than the concrete pavement."

"But the reason why I say it is faster is because I have discussed with Lu Feng that trains have an advantage, and their carrying capacity and speed should be much faster than those of carriages. In this way, trains originating from Industrial City can directly transport large amounts of supplies to the front-line construction through the railway tracks built while continuously rushing to the front-line construction."

"In this case, its speed will be much higher than the speed of carriage transport. Because our cement is currently mainly produced in Industrial City, the further away the concrete roads are from our Industrial City, the slower the construction speed." Wang Luo said quickly.

Huo Gang nodded immediately. He did not expect that according to Huo Gang's previous idea, the construction speed of the railway may be much slower than concrete. Because the railway transport of rails alone is a problem, and the carriage cannot transport much, let alone a larger number of stone and other materials.

However, after Wang Luo said this, Huo Gang suddenly realized that in the railway construction in later generations, not to mention laying railway tracks, just laying foundations and stones, there were more advanced other transportation systems in later generations, especially the pavement of railway tracks, construction machinery and raw materials that could almost be used locally.

The premise of local materials is that there are roads in any place, as well as construction machinery such as stone crushers to create material places for roadbeds, so the roadbed paving of the entire railway is built from all directions one by one.

Secondly, although there were special rail laying trains in later generations, the rails and concrete sleepers were assembled near the construction section, because a railway was divided into countless sections and started construction at the same time.

In this way, the construction speed will be faster, and transporting rails is not a problem that needs to be considered in later generations.

What’s different in this world is that all the construction machinery is currently concentrated in industrial cities, including stone crushers, concrete, steel bars, etc., which is why Huo Gang fell into a misunderstanding of thinking.

He felt that these materials were transported to relevant locations by carriage, but in fact, this did not need to be the case. First of all, the railway construction in this world does not need to affect any other roads.

Secondly, there is not much demand for railways in this world. The main result is that it was born for the first time and will not affect other problems. The speed of construction is worse than just extending directly from the industrial city.

So even when it was built one kilometer long, steam trains could actually be operated, because steam trains, unlike later electrified trains, require countless accessories, and only a few types it needs. The first is enough fuel, that is, coal, it is best to crush it into powdered coke with different ingredients, which has more sufficient combustion.

The second is water. Every distance of railways requires stations for adding water and coal, which are not difficult.

In fact, the train itself is large enough to transport a large enough water behind the locomotive. It is not difficult to pull coal carriages, which means that the distance the train can travel far exceeds imagination.

So if the locomotive for this test can provide enough power, then the railway tracks are laid for 10 kilometers, and the train can directly pull 10 kilometers of supplies from the Industrial City to the laying site, and then the workers unload the relevant supplies, and then the train returns.

Anyway, it is estimated that the construction team will take at least many days to consume the materials loaded by the train. In many days, it is enough for the train to re-draw goods and return. As for the train to return, it is even simpler. Whether it is to establish the ramp used for interaction or use a two-way locomotive.

"Have these rails been tested?" Huo Gang asked.

"We have tested them. Their strength is the hardest one we chose, including the deformation resistance you mentioned by the leader, etc. However, because we have no relevant experience, at present, we can only improve while testing." Lu Feng nodded immediately.

"Yes, during the test of the rails, it's enough to easily replace the rails." Huo Gang nodded immediately. It's good that they can play the train now. These rails are about 12 meters apart, which means that a certain gap should be reserved between every 12 meters to prevent thermal expansion and contraction.

Their technology is simply impossible to play with the seamless rail set. Not to mention Huo Gang, China's railway paving in later generations can be said to have reached its peak after entering the first decade of the new century. However, for trains, seamless rails were only used after the birth of the EMU. All rails were forcibly fixed to the sleepers with fasteners, and stress coefficients such as thermal expansion and contraction were no longer considered.

The entire rail is forcibly fixed, because the rails with gaps cannot reach too fast, but that is a long-lasting state for Huo Gang. In his lifetime, he can see the development of internal combustion engine trains. Thank God, what other bicycles do you need?

You should know that the steam train has been used for at least two centuries.

"Yes." Lu Feng nodded immediately.

Huo Gang looked down at the sleepers half buried in the gravel below him and the railway tracks fixed to the sleepers, which were almost exactly the same as later generations. The only difference was that there were not so many electrification equipment on both sides of the railway tracks.

He reached out and knocked on the rails, Huo said, "Go and see your train."

"yes!"

Everyone immediately raised their legs and walked towards the workshop several hundred meters away.

After Huo Gang entered the workshop, he saw the very conspicuous locomotive that had been assembled on the rails. Seeing this locomotive, Huo Gang couldn't help but be amazed. First of all, this locomotive is completely different from what Huo Gang saw in his previous life.

Its appearance is even closer to the relatively mature steam locomotive in later generations. It is about ten meters long, with several huge chimneys on it, and a chimney that discharges a small amount of waste steam. It is connected behind it to a carriage for people and people. The surroundings of the carriage are also made of thick glass, and behind this carriage is next to a huge carriage.

Needless to say, this carriage is used to pull coal. At that time, the burning coal will be added to the boiler in front by the workers who drove the train. This design is actually very close to the mature design of the steam train. Huo Gang doesn't want to know how they tried to get it, but Huo Gang's role in it can be said that it is not too great.

Of course, it cannot be said that it is not bad. The inspiring opinions he gave are definitely very useful, but the specific design aspects were not actually carried out by Huo Gang.

"You must have tested this, right?" Huo Gang pointed to the train and asked with a smile.

"Yes, we have tested it more than fifty times." Sun Er and Lu Feng said embarrassedly. After all, they had never told Huo Gang before the test, "But we have never tested this fifth-generation steam train once, but we have only statically tested the steam and other abilities."
