Seoul Subway Line 7 of the Seoul Metropolitan Rapid Transit Corporation was built 1990–96 (Jangam-Konkuk Univ.) and was completed August 1, 2000 (central section 17 km. Konkuk University to Sinpung); the western section between Sinpung and Onsu was put into service on February 29, 2000. This north-south line does not run through the city centre but links Gangnam directly to the northern parts of town.
All the trains on Line 7 are monitored by 1,008 closed-circuit television cameras that were installed in June 2012.
The extension to Incheon Subway Line 1 was designed to relieve the traffic congestion in western Seoul and northern Incheon. Nine stations were added October 27, 2012, for the 10.2 km extension, starting from Onsu Station of Line 7 and ending at Bupyeong-gu Office Station of Incheon Subway Line 1.
There are two future planned stations, Baekmajang and Seoknam, the latter of which would be a transfer station with Incheon Subway Line 2. Construction on the 3.94 km extension began in 2013 and is due to be completed in 2020.
The further extension, in the conception stage as of 2012, would see the line extended another 12.2 km ending the line on Yeongjongdo, the same island that houses Incheon International Airport. No dates have yet been announced as of 2012.
