St Petersburg, platform steel doors

Metro Bits http://mic-ro.com/metro/ Train doors are closing first, then the black platform steel doors (hardly visible because a woman walks past in precisely that moment). The steel doors in this station and a couple of others are there for constructional reasons. They are unique in the world since other cities have either platform screen doors made of glass or no platform doors at all.
