Hong Kong's MTR system

Thought my readers might find this interesting and cute:

But more so, that none of these are taken in the HK subway, or MTR, which i assume means metro transit railway? In any event, my value add is that I find that the MTR HK is one of, if not, the worse in the world. Very typically HK, it is very efficient, but not very effective. Basically, crowd control is carried to the extreme, with little effect. Terrain, up and down, are so varied, it would take less time to walk on the surface, etc, etc.....

And I have been in the subways, in just about every major city in the world.......
