Even in China, flying is usually cheaper than HSR, and over twice as fast once airborne (300km/hr train vs 800km/hr plane). But getting and through airports is still more of a hassle than the trains. Even when taxis are fairly cheap, there's nothing like popping out in the city.

Though it's not quite like a cosy European station near the old town: some some stations are the better part of half a mile across (not along the platforms, across), and aren't right in the city centre so there can still be some walking involved!

On the other hand, you can have takeaway food delivered to the station ahead and receive it at your seat. And it's far more comfortable even in economy.
