Hearing Voices

On the MTR - the train network for Hong Kong - the announcements are in Putonghua (Mandarin), Cantonese, and English. One thing I like about MTR is hearing the voice of an English (as opposed to an American) woman announcing things like "The next stop is: Sha-Tin". It's very refreshing.
One thing I don't like is that the train tracks are open-platform style, i.e. you can jump on to the tracks. Kowloon Bay station is the only one I've seen so far with shoulder-high barriers that only open when lined up with the doors of the train.

In Seoul, most platforms have a shell-like appearance; there is no way of getting on to the tracks because the floor-to-ceiling doors only open when they line up with the train doors. It is only the older lines where the platforms are still open-style.
And Seoul Metro has announcements in four languages - Korean, English, Putonghua and Japanese.

Moot Point: The same thing for both systems, and I'm guessing for metro systems in most large Asian cities, is the 'manners'. First-come first-serve to sit down (normally regardless of age or frailty), and people piling on to the train as soon as the doors open and not letting you get off.

Winner Round One: Seoul Metro.
