After a night of carnival, the next day, a new day began, and Cai Ruichen harvested a group of more enthusiastic people.

What was different from usual was that this time in the canteens of the various collective communes, every survivor was able to greet the soldiers who were eating with them very cordially.

The soldiers also responded to their greetings very politely.

It wasn't until I started going to work that the relationship began to return to normal.

All the survivors lined up on the streets of Xiaxi Town boarded their trucks one by one, and there was a group of survivors who were the largest, almost a thousand.

Dozens of buses pulled them to the outermost perimeter of the base, where they were surrounded by a large number of heavily armed soldiers.

These soldiers are not here to supervise them, but to protect them.

With the beautiful living environment in the base, no one will choose to leave, let alone escape.

The protection of an entire armored battalion provides safe protection for these thousands of survivors.

Because they were out of the confines of the base, there was no wall to protect them.

And here, a railway around the base is being built.

That's right, it's the railway.

At the time of the lowest level of scientific and technological authority, Cai Ruichen extracted the science and technology railway, and the so-called science and technology railway is actually an advanced high-tech railway station.

But Cai Ruichen has not built this unit for a long time, because at that time he had not yet extracted the unit of railway laying trainsets.

There is no need to build a railroad today, and there weren't as many workers in the wasteland back then.

Now everything is different, and at the moment the base will be within ten kilometers of the place. It was all protected by a fence.

Such a large area. The distance between the farthest two points within the wall. It has already reached twenty kilometers.

It is also more necessary to build some fast and exciting railways for the rapid transportation of weapons and ammunition or the mobilization of troops.

Although the number of trucks in the base is now sufficient, the transportation of trucks is convenient, but at the same distance, it is not as fast as the faster cargo sports vehicles.

The bullet train running around each wall of the base can quickly transport the necessary materials or troops to any point.

And in the future, the area of the base will continue to expand. Short-distance and fast rail transportation will become more efficient.

The most important thing is that among the trains that can be produced by the base, the pace is armed with trains, which is what Cai Ruichen wants.

Whether it is a missile train in the future, or a railgun train, as for the ballistic missile train, it is a good thing.

Therefore, Cai Ruichen felt the need to start building the railway now.

If it weren't for the fact that the construction of the Air Force Headquarters and the expansion of the airfield had already begun, he would have planned to start between Marin Town and Samarra. Construction of a two-way railway line.

Bites back and stutters, and is currently enriched by human resources in the wasteland. So the laying of the railroad started from the wasteland.

With automatic railroad laying trainsets, in fact, the people who build railways are not tired at all.

Because whether it is digging the foundation of the railway, putting cement pier sleepers, or rails, screwing and filling in the rubble, there is no need to do it manually.

More than 100 meters long automatic railway-laying trainsets can complete some of this work automatically.

And what they have to do is to lay the trainset with only this automatic railway.

In fact, the automatic laying of railways was first invented by the Germans in the last century.

And most of the railways in Europe are all completed by this track-laying train.

Even the United States does not have this equipment, and only Deutsche Bahn has such technology in the world.

But in the wasteland, similar laying of railway trains, is very common, and there are many records of this in the transportation literature.

And some of these survivors don't need to be taught by engineers, and they are already very proficient in using this equipment.

And what they have to do every day is to drive the automatic railroad laying train from the makeshift garage inside the fence and along the already paved railroad to the outside of the fence.

Then follow the previously laid railway and continue to work forward.

In front of the railway, a special large engineering vehicle digging a trench has already begun to work, and under the engineering vehicle, there are two large shovels of special structure, and as the engineering vehicle advances, a trench for reinforcing and laying the railway is dug just right.

The automatic railway-laying trainsets, which follow behind, will start working on the ditches.

There are six conveyor belts on the trainset, the upper three conveyor belts are stacked with rows of cement pier sleepers, and the lower three are neatly arranged rails vertically.

Together with these rails and cement pier sleepers, the total weight of this automatic railway-laying train set reached 3,000 tons.

It is possible to walk on tracks, or on the already laid railway.

The reason why there are two ways is to ensure that he can complete the laying of the railway without a railway foundation.

As for the railway walking function installed in the middle, it is because of the needs of the work.

Because the sleepers and rails that are automatically lowered also need to be reinforced, and the gravel transported also needs to be covered on the railway.

All of this needs to be done by the trainset, which requires him to be able to run on the tracks.

As the work began, some people drove trucks to the gravel plant to deliver the gravel, and others began to inspect the railway ditches.

Most of them climbed onto the trainset, and some of them sat on either side of the train near the ground.

These people, the first one with a rubber cushion ring, the latter with a latte cushion ring, and the last one with a huge rivet.

After the trainset began to run, the cement pier sleepers on it began to be placed in the ditch by the robotic arm under the conveyor belt, followed by several people to do the work of adjusting the sleepers.

A few sleepers, a section of rails, and the busy work began.

Four hours later, the rails and cement piers on the trainset were all used up, and a five-kilometer-long railway was simply laid, and then the trainset slowly retreated.

It was the turn of the men on both sides, and as the train set retreated, they quickly bent down to insert rivets and gaskets into the drilled holes of the rails and sleepers.

The hydraulic hammer machine that retreats from the front of the train locomotive is to nail the prepared rivets directly into the cement pier when it retreats all the way, and completely fix the sleepers and rails.

At this time, the trucks that delivered it also began to pour gravel on the side of the fixed rails.

Then another construction car, an inclined funnel, quickly covered all the sand and gravel onto the rails, and a section of the railway was completed.

A trainset, ten hours a day, has an average efficiency of ten kilometers per day. (To be continued.) )
