Seoul Subway Line 2 (dubbed the green line) is a circular line of the Seoul Metropolitan Subway. The line running clock-wise is called the "inner circle line" and the counter clock-wise line is called the "outer circle line." This is Seoul's most heavily used line, and the longest circular subway line in the world. (Total length: 60.2 km)
Line 2 was built 1978-84 together with the Seongsu Branch (the second Sinjeong Branch was built 1989-95). Dangsan bridge was closed for reconstruction in 1996 and reopened on 22 November 1999. The old steel girder bridge was replaced by a 1.3 km long concrete bridge between Dangsan on the southern side of the river and Hapjeong on the northern bank. Headways on the line can now be reduced to 30 seconds, off peak intervals 5-6 min. The line connects the city centre to Gangnam (south shore), the second city centre.
On Oct. 20, 2005, Yongdu Station opened on the Seongsu Branch (between Sindap and Sinseol stations). It is the first station in the Seoul Subway system to open with operating platform screen doors. As of May, platform screen doors are operating at 10 other stations. New rolling stock is also progressively coming on line.
Line 2 stops at these stations:
