Seoul Subway Line 2 (dubbed The Circle Line) is a circular line of the Seoul Metropolitan Subway. The line running clockwise is called the "inner circle line" and the counter-clockwise line is called the "outer circle line". This is Seoul's most heavily used line, and consists of the main loop (47.7 km), the Seongsu Branch (5.4 km) and the Sinjeong Branch (6.0 km) for a total line length of 60.2 km. The Line 2 loop is the second longest subway loop in the world after Beijing Subway Line 10.^[1]

Headways on the line vary from 2 minutes 18 seconds on peak periods ^[2] and 5–6 minutes off-peak periods. The line connects the city centre to Gangnam, Teheran Valley and the COEX/KWTC complex.

History

Line 2 was built in 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-kilometre (0.81 mi) long concrete bridge between Dangsan on the southern side of the river and Hapjeong on the northern bank.

Yongdu Station on the Seongsu Branch (between Sindap and Sinseol stations) is the first station in the Seoul Subway system with operating platform screen doors. As of 2008 platform screen doors are operating at all stations along Line 2. New rolling stock has also progressively came on line, replacing older vehicles.
