My task is to document Seouls metro history. However, I'm from Czech Republic which limits selection of sites I can get data from. (I don't speak Korean, and google translate usually fails).

Also, Seouls is relatively new so it's history is not as documented as coustruction of old European metros.

An information that I miss very much is date of the first sucessflly instaled platform security door and in which station was it.
