Orthan is right about whether this would be a commercial success. That's a whole other problem to the engineering one of achieving the performance.

In any case, this is about a project that is planned. Granted this is well above just ppt or model level, there is a lot of work left to make this, mass transport possible and commercially viable.

I highly doubt CRRC would openly, repeatedly declare their train is 600km/h, and say it's the "first 600kmh train" if they were not confident of achieving it as operational speed.

Didn't someone say this project is aiming to deliver service in 5 to 10 years?

Honestly what is the deal with this train? Have they tested this vehicle or is it just a mockup? What is the development timeline?

If service is to be achieved in 5 to 10 years time, they would only have barely started on everything apart from the core tech which would still be lab levels of reliability and cost.

I think the train is ok

AFAIK the difficulty is in the track

If everything is almost completed and it's really just waiting for track construction, it should only take a few months to construct a long enough track for service and maybe a few years for providing actual commercial service between two major cities. 5 to 10 years before commercial service indicate many pieces of tech involved have not yet matured enough for commercial service.

I think the 5-10 years means getting the government to build an actual commercial line, not 5-10 years for it to be ready

Sections of the Beijing-Shanghai and Beijing-Guangzhou lines are already at full capacity.

So if you're going to build yet another new line, it might as well be a faster one if the economics can work out.

Distance wise, Beijing-Shanghai is 1300km which means a Maglev would should take less than 2h20min.

That is short enough for premium ticket charge for travellers on day-trips for leisure or for business.

Currently there are 210 million passengers per year on the Beijing-Shanghai line.
And if I look 10 years ahead, there's probably enough demand on this route for another 200 million passengers per year.

There are major traffic nodes at either end of the line: Beijing-Tianjin and also Nanjing-Shanghai-Hangzhou

A similar calculation applies to the Beijing-Guangzhou/Shenzhen route which is much longer at 2200km.
That also means there are more city-pairs which have viable journey times of 1h30min - 5 hours

5-10 years to build a train line? taking into account how fast chinese companies work, and the fact that only now the train was unveiled, i doubt that. I think that the train/track are still in development phase.

I highly doubt CRRC would openly, repeatedly declare their train is 600km/h, and say it's the "first 600kmh train" if they were not confident of achieving it as operational speed.
The train is 600 km/h. Calling it "first 600kmh train" could have been a public statement lapse/mistake.
