In fact, Maglev also has much better elevation and curve performance. Basically solves all the issues except aerodynamics which is why I think Maglev is a good solution.

I just don't see it happening so quickly right after China finished its HSR system
Maglev also solves that problem.
exactly. it is costly to solve what is otherwise for marginal gains. There's a reason why air travel also isn't speeding up - the bottleneck soon moves from the travel time to station stops, etc.

I think a full network of maglev will only be built, if ever, in the far future. Instead, it will be built on routes where the HSR capacity is maxed out to relieve the pressure. The vacuum train, IMO, will be used to quickly cover vast distances (thousands of kms) between massive metropolitan areas. The 4000 km/h train (wich I'm pretty sure is a moonshot project as of now) is, if I remember correctly, a transcontinental (and maybe oceanic) train.

Eh, I have huge doubts to those maglevs operating in any kind of vacuum tubes or the likes.

Although reducing the air in them to like, 1/1000 of regular atmosphere or the likes, basically hugely reducing air resistance sounds a lot more plausible and likely.

True. Although the system is called vactrain, it will only use low vacuum. High vacuum will probably be necessary for the 4000 km/h train but, as I said, that's currently nothing more than a moonshot project.

Я считаю, что лучше снижать аэродинамическое сопротивление не с помощью вакуума, а с помощью специальных материалов. Проводятся ли какие-либо исследования по снижению сопротивления воздуха с помощью плазмы?

China completes cutting medium- and low-speed maglev tunnel with shield tunneling machine

China completed the cutting of a medium- and low-speed maglev tunnel using a shield tunneling machine in Changsha, capital of central China's Hunan Province, on Saturday.

This maglev tunnel is the first of its kind worldwide to apply shield tunneling, according to its developer China Railway Construction Corporation (CRCC).

The shield tunneling method helps to ensure that ground subsidence is limited to 0.2 millimeters, the company said.
The 2.85-km tunnel, 27 meters below the earth, is part of the east extension of the Changsha Maglev Express.

China's first home-grown maglev line, which shuttles between Terminal 1 of Changsha Huanghua International Airport and Changsha South Railway Station, began operations in 2016.

In the past seven years, the line has run 373,139 trains and served about 20 million passenger trips, according to CRCC.
With the newly-built maglev tunnel, the line will soon be able to lead directly to Terminal 2 and Terminal 3 of the airport.

The east extension line of the maglev is part of the airport's reconstruction and expansion project, aimed at realizing fast and convenient "air-rail" combined transportation in Changsha.

BEIJING — In the last two years, China has announced the opening of new freight train lines, while cross-border railways have become a feature in President

’s meetings with regional leaders.

It’s all part of Beijing’s Belt and Road initiative, a complex network of infrastructure projects connecting China to its trading partners.

In April, China’s national rail ticketing app opened online bookings for a 10.5-hour train ride from Yunnan province to the capital of Laos. If all goes as planned, that route will one day connect to the Thai capital of Bangkok and Phnom Penh, Cambodia’s riverside capital.

In the last six months, China also opened freight train lines to

are underway, according to state media.

While it’s difficult to verify how operational all the rail lines are, official reports offer a glimpse at how China’s Belt and Road ambitions are panning out.

CNBC analyzed the reports to create the following schematic diagrams of the railways, built and planned, by region:

China’s Belt and Road Initiative was launched in 2013 at the beginning of Xi’s presidency. The program is widely seen as Beijing’s effort to boost global influence through the development of rail, sea and other transportation routes running from Asia to Europe and Africa.
“Splitting Europe from the U.S., at least to the extent possible, is an important foreign policy objective for China and deeper economic integration fostered by stronger rail linkages would help,” said Stephen Olson, senior research fellow at the Hinrich Foundation.

Similarly, “part of China’s motivation in constructing rail links in ASEAN is to place China more at the heart of regional trade,” he said, referring to the 10-member Association of Southeast Asian Nations bloc.

Olson said that while rail could be “game changing” for a landlocked economy such as Laos, the onus is also on the destination country to develop logistics and other infrastructure to fully utilize the new rail lines for trade.

One-third of China’s trade​

Beijing says trade with Belt and Road countries accounts for about one-third of China’s overall imports and exports. In the first quarter, that trade grew by 16.8% from a year ago — slower than the 19.4% pace for all of last year, according to official figures.

The actual boost to trade from the rail lines is difficult to gauge, said Francoise Huang, senior economist at Allianz Trade. She pointed out that transporting goods by rail is considerably cheaper than air, and faster than by road and sea.

She said her assessment of reports indicates the rail lines are being used more to transport Chinese exports to other countries, rather than imports into China.

Since 2013, Belt and Road-related construction contracts have

according to estimates released in January by Christoph Nedopil, founding director of the Green Finance and Development Center at Fudan University in Shanghai. Including non-financial investments, that figure rises to nearly $1 trillion, the report said.

Critics say that through the massive infrastructure project,

while benefiting Chinese companies, often state-owned entities.

“Analysis of the impact of the freight lines will be indivisible from an analysis of the overall impact of closer trade relations with China,” Olson said.

“For some countries this might work out better than for others. China’s economy is far larger than any single economy in ASEAN and that creates leverage that can sometimes result in unbalanced and unsustainable trade relationships.”

In an annual report in March, China’s National Development and Reform Commission, the top economic planning agency, highlighted progress on international rail construction. The commission also said it was cognizant of risks.

“We developed major overseas projects while guarding against related risks, helped enterprises guard against and defuse overseas investment risks, and worked faster to build a comprehensive service platform for monitoring, assessment, and early warning of risks related to overseas projects.”
