You can still use a train.

Not in china though:

I've read that is wrong, depending on what you define as (usable) train.

Allegedly there are the 'green' trains, because using older green wagons.

They aren't high-speed, but drive everywhere. As do busses. Which allegedly you can use. Just takes longer.
