Remember most of the Chinese train infrastructure was built in the time since the Hyperloop.

Chinese train infrastructure also had a lot more casualties than any modern Western nation, even with a conservative estimate of the covered up ones. Building fast is a lot easier if you can break some eggs.

You mean casualties among workers building it? Or casualties among the passengers traveling on it?

I was not impressed when I was sent there on business trip, from what I remember their subways were not as big as in Beijing or other CN places and I hit there my head, obviously anything is better than HK/London. Normally I'm not claustrofobic, but in HK subway...
