Chapter 332 New plan

At the beginning of September, due to the opening of the Strait Cross-Sea Bridge and the management company of the Strait Cross-Sea Bridge invited fans to test train passenger transport, it attracted a lot of public attention.

In addition, the Yinhe Consortium announced that it will build another longer cross-sea bridge, starting from Weihai City, East Tanglu Province in the west, and ending in Tai'an, Gaoli South Chungcheong Province in the east. The entire cross-sea bridge is 306 kilometers long.

At the same time, the East Island Loop Vacuum Railway has also entered the construction stage, and the East Island Loop Vacuum Railway will be connected with the vacuum railway of the Strait Cross-sea Bridge.

The inland Pingtan-Shanmei vacuum railway has also entered the construction stage.

In fact, the Dongtang Railway Department has sent several expert groups to the Strait Cross-Sea Bridge. They are very optimistic about the vacuum railway and are discussing how to upgrade and transform the high-speed railway.

The plan of the Ministry of Railways is to use the original railway lines to lay vacuum railways. Planet Group also agrees with their idea.

After all, if the existing railway cannot be used for upgrading and reconstruction, and a new line is built, 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 were quite familiar with each other.

Chen Wenfeng smiled and nodded with the other party.

And beside them was Su Yue, the general manager of the Strait Cross-sea Bridge Management Company.

"If the existing railway is used for upgrading and transformation, I don't know if this technology is too difficult, and how much additional cost will it cost?" Liu Weihong asked, getting down to business.

Ma Sixing thought for a while: "It's not that 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 Cross-Strait Bridge costs 8.7 million yuan. If it is laid on the original foundation, plus laying on land, the cost will be about 1.5 million yuan per kilometer." Chen Wenfeng added.

"Is it 1.5 million per kilometer?" Liu Weihong figured it out.

At present, the total length of domestic railways is about 12.6 kilometers. If all the vacuum railways are transformed, at least 18 trillion yuan will be needed. Obviously, the transformation cost is unbearable.

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

"Exactly, if the railways across the country are upgraded, obviously we cannot afford the cost." Liu Weihong said helplessly.

"Actually, judging from the current cost of the vacuum railway, the price is still a bit high, but if you really want to build a vacuum railway, I suggest starting with the main line and then proceed step by step. After all, as time goes by, the cost of the vacuum railway It will gradually decline." Chen Wenfeng suggested.

Regarding Chen Wenfeng's proposal, Liu Weihong nodded and said: "This is indeed a pragmatic plan. We need to eat every bite. We can't become fat with one bite."

"There is no problem in building a vacuum railway on the main line, but how to coordinate the vacuum railway and the ordinary railway?" Ma Sixing reminded.

The coordination problem he mentioned is not only that when the vacuum railway is built, it will make the railway impassable; another big problem is how to make the train communicate with the two systems after the completion. After all, the ordinary railway system and the vacuum railway system are different.

"This is indeed a problem. We want to upgrade and renovate the main line, but the main line is a very important traffic line. Once the laying and renovation start, it cannot be used." Liu Weihong said with a headache.

"There are many methods. My idea is to quickly lay the construction 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 prefabricate all parts in the factory in advance, and take [-] kilometers as a section, and strive to complete the laying of [-] kilometers of vacuum railway within a week, and then quickly open to traffic .

In addition, they can avoid the peak season of holidays and choose some off-seasons for construction.

It is true that this year's holiday peak period of railway transportation is not as crowded as in previous years, mainly due to the sudden emergence of airship transportation, which took away part of the passenger flow.

Especially in Yunnan-Guizhou Plateau, Qinghai-Tibet Plateau, and remote mountainous areas, airships have become the 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, it seems that it can’t compare with the speed of high-speed rail and airplanes, but don’t forget that airships travel in a straight line, so 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 that of airships. As one of the top two passenger airships, Spring Airlines has launched the cheapest airship ticket for 100+ kilometers.

The so-called 100+ kilometers means that the starting price is 100 Chinese yuan, and there is no additional fee within 50 kilometers. After 50 kilometers, it is 10 Chinese yuan for every 1 kilometers.

For example, the straight-line distance from Yangcheng to Shanghai is 1190 kilometers, and the airship ticket price is 100+114=214 Chinese yuan. If you buy an air ticket, it is generally more than 600 Chinese yuan.

Coupled with the cheap flights of Spring Airlines, it can transport 1500 people at one time. For those who are relatively cash-strapped, this price is very considerate.

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

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

"Is it too late to lay 100 kilometers of vacuum railway in a week? If there are quality problems, it will be troublesome."

"Don't worry, Mr. Liu! I can assure you that there will be no problem in this regard. When we are constructing at sea, we can lay 20-30 kilometers of single-line in a week. On land, this speed will only be faster." Chen Wenfeng assured.

"I also think that this speed can be achieved. If we prepare in advance, such as the treatment of the roadbed, the laying of the power supply system, and the setting of the vacuum station, these can all be prepared in advance." Ma Sixing echoed.

"Then we will start with the line from Shanmei to Pupingtan, and use this line as a pilot. If there are no problems, we will upgrade and transform other trunk lines." Liu Weihong made a decision.

Next, the group took the HX-KY003 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 accordance with normal operation.

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

[Pingtan Station (starting station) - Hsinchu Station (terminal station)]
[Time: 2019.09.13/14:24]

[Speed: 1214 km/h]

……

"I don't even feel acceleration and vibration at this speed. Your technology is very mature." Liu Weihong sighed.

"This is almost the most cost-effective speed. It is true that we can make it faster, but the loss outweighs the gain." Chen Wenfeng explained with a smile.

"What Chen said is not wrong. Once the speed is too fast, not only the acceleration will be a trouble, but also the acceleration from the start and the deceleration from the stop will be very troublesome." Ma Sixing also said helplessly.

"This speed is already very powerful. As for the faster vacuum railway, it is estimated that it can only be applied to intercontinental railways." Liu Weihong is already very satisfied with being able to achieve this level.

While the few people were talking, the train was slowly stopping at the inbound area of ​​Hsinchu Station.
