The line patrol drones flew back and forth, and countless people were busy hammering and tapping.

Drones are good, but currently they are only used as an aid to find and fill gaps. Real railway line inspections still have to be done manually.

Even in 2023 in another world line, with more mature and smaller drones, railway line inspection is still so simple and unpretentious.

In hot summer days, they patrol under the scorching sun; in winter, they patrol under the cold wind; they patrol in the coldest days of winter and the hottest days of summer, without stopping day after day.

This time, in addition to helping, Alia also brought a team of engineers with her.

This is in order to hand over information to the railway system, make adjustments to tools, and further optimize the "customized" drones.

The railway system has received about 200,000 drones so far, and Alia has decided to donate them all to the other party.

However, the relevant data maintenance has not been neglected, and the donation of these technological products should not be a one-time transaction of delivery and receipt.

However, it was not only engineers who came from the railway side, but also senior management who came.

"Hello, hello. You are Miss Ai, right? It is true that heroes emerge from youth!"

A man not in uniform came up with a big laugh and shook hands with Aaliyah warmly.

The other party was not wearing a uniform, but just a work suit and a white safety helmet.

But following behind him was a group of people with shoulder straps and three bars. What does this mean?

You have to know that the railway system has job ranks. Those without bars on their shoulder straps are front-line employees.

The shoulder strap has one bar and is usually worn by management personnel, or dispatchers, crew members and other employees.

Those with two bars are management personnel. At the station, they must be management positions above the level of deputy stationmaster.

Three bars - that means the lowest rank is deputy director!

As for those who don't wear uniforms and don't have stripes, but are accompanied by a group of people with three stripes, it goes without saying that they are senior executives.

The two sides introduced themselves, and Alia finally understood the other party's identity.

He is indeed a senior railway executive and an engineer by training, so he came here to coordinate with us.

"Your name?"

"Excuse me, your surname is Gao——"

"Senior Engineer, nice to meet you..."

Aaliya said that I am still young and not good at speaking.

Engineer Gao said it was a coincidence, he was not used to small talk and there was no need to be so polite.

The engineers from both sides exchanged data and set up various equipment in the maintenance station, and then the two stood aside and chatted.

"This time, it's really troublesome. The machine adjustment has to be put on the main line."

"Has the contact network not been repaired yet?" Alia frowned: "It's been almost a day."

"No, the snow never stops. The electrified overhead line here is something we never expected to encounter."

"Patta——"

As they were talking, a piece of ice fell down and broke into pieces.

When everyone looked up, they could see a row of icicles more than ten centimeters long hanging from the electric wires above their heads.

This thing will fall down if the wind blows, so everyone present wore a helmet - someone was hit by it before and was sent straight to the hospital.

This is just the railway line where there are not many people. In places like Fucheng where the entire city is frozen, the danger can be imagined.

The railway is not afraid of these ice cubes hitting the head, but with these things, the electrified contact network cannot be used...

Ailia is now in the Hengyang section ahead of Fucheng, and the nearest station is called Xujiadong Station.

Previously, a train stopped here for a day and a night, and then another unlucky guy came and stopped here.

At first glance, there is actually no snow on the ground that would make it difficult to pass.

There was heavy snow, but it melted during the day, so there was only a thin layer on the ground.

At least visually, you can see the gray-black road surface and the rails completely exposed above the snow.

Compared with the spectacular snow scenes in the north, these snow scenes in the south can only make people laugh.

What little snowflakes are here to join in the fun? Are you worthy of being called General Winter?

But the real trouble is not on the ground, but above your head.

Because the voltage fluctuations of the contact network were too large, almost all trains entering the Hunan province area stopped.

In the railway system, the front train often follows the back train, with strict scheduling.

If one car stops, all the following cars will also stop.

When we reached the Fucheng section, the weather started to become extremely cold.

Judging from the weather, there have been sporadic snowflakes floating in the sky for a week.

Fucheng did not become an isolated island, but the situation was not much better either. The Fucheng section of the railway was even more unlucky.

The train, which had been struggling to move forward, came to a complete halt in this area.

A nearby car arrived here the night before yesterday, and then there was a contact network disconnection accident between Fucheng and Hengyang.

And the Internet was not cut off in just one place, but in multiple places.

Throughout the night, all up and down traffic was completely cut off and no train could pass through here.

What can we do? Just wait and see when it can be repaired...

Alia rushed here after hearing the news. Naturally, the people from the railway arrived faster and earlier than her.

It’s just that the primary purpose of both parties is different. Alia is here to help the passengers, and the railway engineering team is here to build the road.

Logically speaking, the person is staying well in the car, protected from the wind and rain, so what's there to help with?

But this is not the case. Since it is a contact network failure, the power must be cut off during emergency repairs, so all electric locomotives on the line must lower their pantographs.

Without electricity, an electric locomotive separated from the contact network is just a pile of scrap metal, a pure iron cage.

What's even more unfortunate is that this matter can't be resolved in a short time...

Freezing rain and ice will greatly increase the load on the contact network, and there will be a thick layer of ice between the pantograph slide and the contact wire.

Otherwise, there's no reason to stop for so long. Just break the ice and be done with it.

It's a one-time thing. We have to quickly connect the power supply to the locomotive so that we can have electricity and heating and have hot water to drink.

However, due to the recent continuous snowfall, the pantograph of the electric locomotive will be completely frozen by the snow within half an hour after it is lowered and cannot be raised again.

If you try to force it, it will cause serious discharge and arcing, and if you are not careful, the already riddled contact network will be burned out.

Compared to the entire overhead line, a few stopped trains are not the focus for a while...

Alia arrived here last night, and then met up with the official emergency material transportation team and got into the car.

Wow, a small market has appeared in the car. The ham sausage is 10 yuan each. This is the current price. I will show you the price increase later!

For people in Lingnan, snow always has infinite appeal. Most of the passengers on this train are from the south, and it was quite lively at the beginning.

But after staying in the cold electric locomotive all night, almost all the passengers on the train were frozen to death. No one was in the mood to have fun. They were tired.

Inside the locomotive with the pantograph lowered, the roof was covered with thick snow and the windows were covered with a thin layer of ice. It was like a steel ice cellar.

What's worse is that this is not a passenger station and the supply reserves are not sufficient.

In the early morning, the maintenance personnel from Xujiadong came all the way and brought the first batch of emergency supplies.

Later, more supplies arrived, and Alia also came with the supplies and had a meat soup noodle breakfast provided by the railway system.

With hot water and hot soup noodles, as well as distributed hot packs and emergency blankets to keep warm, the passengers on the locomotive finally had the heart to watch the fun.

It's strange, yesterday I saw these snowflakes were hideous, but now they look pretty...

"As an emergency plan, we will still use diesel locomotives to pull the ferry and use telephone blocking to operate the train."

"Dongfeng engine?"

"Yes, DF4B, it's an old guy, and the temperature has risen today. Maybe the T-type car will be able to raise its bow and drive out by noon."

The reason why everyone needs to patrol back and forth at this time is that many plants on the roadside have been broken by ice and snow, which will hinder driving.

But as long as the ferry locomotive can come over, it proves that the road is open and everything will be fine.

"What is the front of the DF4B used for now?"

"Freight. At present, all freight locomotives have been transferred to passenger lines. You know what, the crew members like it very much."

I don’t like it. The cab of the diesel locomotive is as warm as spring at this moment.

Alia had seen on other roads before that the flight attendants took turns playing rock-paper-scissors when the car stopped, and whoever won got to get inside the watermelon.

The Dongfeng locomotive, which looks and is painted like a watermelon, has been used as a freight train for many years and has long been retired from the passenger line.

It can even be said that the entire series of internal combustion locomotives seems to be on the decline nowadays. Who doesn’t like a fast and stable tram?

Unexpectedly, he has become so popular now and is loved by everyone. It can only be said that heroes are made by the times.

After a while, Xigua arrived. The DF4B diesel locomotive had some mottled signs of time, but it looked so strong and powerful.

Ailia and her group also boarded the train and moved forward. On the road, they could see the Beijing-Zhuhai Expressway without a single car.

The senior engineer was looking around with a telescope. Of course, he was not looking at the friendly forces on the road system, but at the traffic lights.

Because the signal lights were all frozen, the roads were filled with railway workers waving small flags and standing guard in the ice and snow, acting as human signal lights.

After walking for a long time, we finally saw a temporary train going down the river, and the temperature had also risen.

"Pit in, make some adjustments, raise the double bows and run, and help scrape the ice."

Engineer Gao put down his telescope, breathed a sigh of relief, and issued the dispatch order.

Raising the double pantograph can, on the one hand, prevent the lowered pantograph from being frozen.

On the other hand, the front pantograph can be used to scrape off the ice on the conductor and improve the current receiving conditions of the rear pantograph.

Although sparks and arcs will still occur, the danger is not as great as before, so it is still an acceptable loss.

Alia got off the car. The site was much larger, and a yellow power supply maintenance vehicle could be seen next to it.

Alia had seen them last night and they were still busy now. They probably hadn't rested all night.

The entire station is now crowded with cars, all of which are friends who were "hospitably" kept by the Fucheng section. Everyone's next stop is Zhuzhou.

At this point, the watermelon can be taken down.

Everyone was quite reluctant to leave, and some passengers came out to take photos with these old brothers in their memories.

When they were young, it was these big watermelons that led the way. They didn't expect that after twenty or thirty years, it would still be them that brought them home.

"The subsequent overhead contact network is intact. In just over an hour, the train will reach its destination."

The train crew came over to discuss the situation. Normally a trip takes them ten hours, but this trip took almost forty hours.

The drivers and passengers were so dizzy from being on duty that they wore out several pairs of straw sandals - yes, straw sandals - which are non-slip.

The Donghuang people have a hundred thousand ways to deal with difficulties, but in the end most of them will choose the most simple but most useful one.

Straw sandals are worn over leather shoes. These straw sandals were not brought by Alia, but were temporarily found by the maintenance group. Each flight attendant was given a bunch of them.

After bidding farewell to the train arriving at her destination, Alia also changed trains to a Harmony train.

Gao Gong and his friends also came over. Alia glanced down and saw that Gao Gong had adapted to the local customs and was wearing straw sandals under his leather shoes.

The Harmony is still the same as before, with a white body and a semi-circular head. This guy is still CRH1, not the new car with a pointed head.

When I went over to take a look, everyone was eating rice enthusiastically. They were probably very hungry.

After careful questioning, I found out that they were even more unlucky than the previous train that broke down...

As we all know, high-speed trains are fast. You can get on a train at noon and get off in the afternoon, which is not even time for dinner.

Who eats on the high-speed train?

But if you fall on the road, it will be terrible!

The train had been out of ammunition and food for the entire day, and the food reserves were used up at noon, leaving no food for dinner.

More than a thousand passengers were in a state of agitation. How could they not be agitated when they had no place to buy anything with their money?

Ten yuan for a sausage and fifty yuan for a bucket of instant noodles, that’s something you have to have!
