I don't know but it seems like the simple answer is to just not accelerate that fast. I doubt this was an attempt to imply that we should do this regularly. It's just a test to show what the technology is capable of. There's no real benefit to accelerating to that speed that quickly vs doing it over 30 seconds or longer.

You can absolutely accelerate this fast if there are no people on board. China probably wants safe autonomous cargo trains at some point.

What about eggs lol

Autonomous 500kph cargo trains would be fantastic.

[–] jol@discuss.tchncs.de 1 points 4 days ago (1 children)

Why would they transport eggs this way...? Fast (expensive) cargo trains would be used for valuable products. For example minerals, metals, computer chips.

Have you seen the price of eggs?

[–] jol@discuss.tchncs.de 1 points 4 days ago

That's a US thing. Also, have you seen the price of everything?

There are non-transportation uses for it. Namely for weapons.

Call me a victim blamer, but if you let your enemy build a superconducting maglev rail from their territory to yours, I feel like that's on you.

Mr President, a second train has hit the Twin Towers.

You can't think any non-living thing someone would want to transfer beyond weapons? 😂

Definitely a “look what I can do” test and not a practical example of how the trams in Beijing will travel between stops. Though it would reduce trip time!
