This looks like the escalator situation in Seoul.  Not only are a ton of people waiting for the escalator but the subway is so far underground that there are 2 and sometimes 3 sets of these!

[nikhak: HAHA- Amazing. I’m totally that person on the stairs (except for moments when I have a sprained ankle, which was recent!). I gave a speech once on how simple it is to improve your health by changing your normal routine - like taking STAIRS instead of an escalator or elevator. It’s easy folks! do it.][via inhll]
