Nowon Station is a transit hub in Seoul where Line 4 and Line 7 connect, near Lotte Department Store and the Culture Street. The transfer structure links an elevated section above ground with an underground section, and there is a rest area inside the station. Escalator construction is under way inside the station, so some exits are closed. The transfer distance between Line 4 and Line 7 is long, which is difficult for elderly and weak passengers.
