At the beginning of September, the domestic government attracted a large part of the public's attention due to the opening of the Strait Bridge and the invitation of fans to test the train passenger transportation by the Strait Bridge Management Company.

In addition, the Galaxy Consortium announced the construction of another longer sea-crossing bridge, from Weihai City, East Tanglu Province in the west, to Taean, Chungcheongnam-do, Colliers in the east, with a total length of 306 kilometers.

At the same time, the East Island Ring Line Vacuum Railway has also entered the construction stage, and the East Island Ring Line Vacuum Railway will be connected to the Strait Bridge Vacuum Railway.

The Pingtan to Shanmei vacuum railway in the mainland has also entered the construction stage.

In fact, the Ministry of Dongtang Railway has sent several expert groups to the Strait Bridge, and they are very optimistic about the vacuum railway and are discussing how to upgrade the high-speed railway.

The Ministry of Railways' plan is to use the original railway line for vacuum railway laying, and the Planet Group agrees with this idea.

After all, if you can't use the existing railway to upgrade, and build a new line, it will be time-consuming, laborious and expensive.

"Chen Suo, Academician Ma!" Liu Weihong, vice president of China Railway Group, was inside Pingtan Station.

"Mr. Liu, long time no see!" Ma Sixing and China Railway are still quite familiar.

Chen Wenfeng smiled and nodded to the other party.

And on their side, there is also Su Yue, the general manager of the Strait Bridge Management Company.

"If you use the existing railway to upgrade, I don't know if this technology is difficult or not, and how much will it cost?" Liu Weihong asked back to business.

Ma Sixing thought for a while: "It's not too difficult, you can use foam cement to quickly lay the vacuum pipe on the original foundation." ”

"As for the cost, one kilometer of the Strait Bridge is 870 million, and if it is laid on the original foundation, plus laying on land, the cost is about 150 million per kilometer." Chen Wenfeng added.

"Is it 150 million per kilometer?" Liu Weihong calculated.

At present, the total length of domestic railways is about 126,000 kilometers, and if all the vacuum railways are renovated, at least 18 trillion yuan will be needed, which is obviously difficult to bear.

"Liu is always thinking about the cost!" Chen Wenfeng asked.

"Exactly, if all the railways in the country are upgraded, obviously we can't afford this cost." Liu Weihong said helplessly.

"In fact, with the current vacuum railway cost, the price is still a little higher, but if you really want to build a vacuum railway, I suggest starting with the trunk line, and then step by step, after all, with the passage of time, the cost of the vacuum railway will gradually decline." Chen Wenfeng suggested.

Regarding Chen Wenfeng's proposal, Liu Weihong nodded and said: "This is indeed a pragmatic plan, the meal needs to be eaten one bite at a time, and we can't become fat by eating one bite." ”

"There is no problem in building a vacuum railway for the main line, but how can the vacuum railway be coordinated with the ordinary railway?" Ma Sixing reminded.

The problem of coordination he was talking about was not just that when the vacuum railway was built, it would make the railway impassable; Another big problem is how to make the train communicate between the two systems after it is built, after all, the ordinary railway system and the vacuum railway system are not the same.

"This is really a problem, we have to upgrade the trunk line, but the trunk line is a very important traffic line, once the paving and renovation starts, it cannot be used." Liu Weihong said with a headache.

"The method is not impossible, my idea is to lay quickly, build in sections, and open to traffic as soon as it is completed." After Chen Wenfeng finished speaking, he was afraid that they would not understand, so he opened the holographic bracelet and made a draft for them to see.

Chen Wenfeng's plan is to make all the parts in the factory in advance through prefabricated parts, take 100 kilometers as a section, and strive to complete the laying of 100 kilometers of vacuum railway within a week, and then quickly open to traffic.

In addition, they can avoid the peak holiday season and pick some off-season for construction.

Indeed, this year's holiday railway transportation peak period is not as crowded as in previous years, mainly because of the sudden airship transportation, which has taken away part of the passenger flow.

Especially in the Yunnan-Guizhou Plateau, the Qinghai-Tibet Plateau, and remote mountainous areas, airships have become a mainstream of transportation.

After all, airships don't need to build roads and railways, and they don't need too professional airports, although the speed is generally 120 kilometers per hour, which doesn't seem to be as fast as high-speed trains and airplanes, but don't forget that airships go in a straight line, and they don't lose to high-speed rail.

As for the speed of the plane, there are a lot of fast airships, the problem is that the transportation volume is not as good as the airship, as one of the two top passenger airships, Spring Airlines, they have launched the cheapest airship tickets 100+ kilometers.

This so-called 100+ kilometers, that is, the starting price is 100 Chinese dollars, no money is added within 50 kilometers, and after 50 kilometers, every 10 kilometers is 1 Chinese yuan.

For example, from Yangcheng to Shanghai, the straight-line distance is 1190 kilometers, and the airship ticket price is 100 + 114 = 214 Chinese dollars, if you buy a plane ticket, it is generally more than 600 meetings.

Coupled with Spring Airlines' low-cost flights, which can transport 1,500 people at a time, this price is very much taken care of for those who are more shy.

So now airship transport has taken away a lot of passenger traffic from airplanes and railways.

After reading Chen Wenfeng's explanation, Liu Weihong also felt that this was a better solution, but he was a little skeptical about laying 100 kilometers of vacuum railway in a week:

"Laying 100 kilometers of vacuum railway in a week, will it be too rushed, if there is a quality problem, it will be troublesome."

"Don't worry, Mr. Liu! I can guarantee that there is no problem in this regard, we are working at sea, and we can lay a single line of 20~30 kilometers a week, and on land, this speed will only be faster. Chen Wenfeng assured.

"I also think that this speed can be achieved if we are prepared in advance, for example, for the treatment of the roadbed, the laying of the power supply system, the setting up of the vacuum station, these can be prepared in advance." Ma Sixing echoed.

"Then we will start from the line from Shanmei to Pupingtan, use this line as a pilot, and if there is no problem, we will be ready to upgrade other trunk lines." Liu Weihong clapped down.

Next, the group took the HXKY003 train from Pingtan Station to Hsinchu Station across the sea.

Although this is a test train, both the service and the internal configuration are in normal operation.

Liu Weihong raised his head, and above it was a holographic projection display.

[Pingtan Station (starting station), Hsinchu Station (final station)]

[Time:/14:24]

[Speed: 1214 km / h]

……

"I don't feel the acceleration or vibration at this speed, and your technology is very mature." Liu Weihong sighed.

"It's about the most cost-effective speed, and it's true that we can do it faster, but it's not worth the cost." Chen Wenfeng explained with a smile.

"Chen is right, once the speed is too fast, not only acceleration is a trouble, but also acceleration from the start and deceleration at the station are also very troublesome." Ma Sixing also said helplessly.

"This speed is already very powerful, and as for the faster vacuum railway, it is estimated that it can only be applied to the intercontinental railway." Liu Weihong is very satisfied with the extent to which he can do this.

When a few people were talking, the train had slowly stopped in the entrance area of Hsinchu Station.
