Not every train stations, but new HSR stations of 1st/2nd tier cities and some of the third tier cities do resemble. One reason is that passengers are now allowed to walk on the platform, so most big railway stations need a huge waiting room with each check-in separated and numbered.
A railway station of a county near my city
Hope it doesn't resemble an airport to you.

back home train, passengers allowed to walk down to the platform just a couple of minutes before train's arrival. And if ANY one crosses the white line, definitely will be pissed off by platform attendants with a loud-speaker.

@anant_s I took this journey actually just for the station I had never been to. Only stayed half an hour there and bought the next train.
I still want to try though.
To live like a king.
I haven't even tried VIP class of Chinese HSR.
