Seoul National University Station has one curved island platform, which is constructed wider at the middle and narrower at each end. The platform screen doors were installed for both tracks within 2006. Escalators are available between the platform and the waiting/ticketing area. Although the name of the station says Seoul National University Station, it takes more than thirty minutes on foot from the station to the university.
In the The Amazing Race 4, teams had to find this station (which was labeled only as Station 228) to obtain the next route marker.
