This is korean subway which is newly extended Bundang line. From seolleung to wangsimni takes only 11min with this Bundang line. Till two days ago, it had to be taken 24 mins this same route with line 2 which is green line. Yesterday extended Bundang line opened newly after very long long time of construction.
