Seoul Subway Line 2
Seoul Subway Line 2 (Korean: 서울 지하철 2호선), also known as 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 (48.8 km (30.3 mi)), the Seongsu Branch (5.4 km (3.4 mi)) and the Sinjeong Branch (6.0 km (3.7 mi)) for a total line length of 60.2 km (37.4 mi). The Line 2 loop is the third longest subway loop in the world after Moscow Metro Bolshaya Koltsevaya line and Beijing Subway Line 10. In 2019, Line 2 had an annual ridership of 812 million passengers or 2.2 million passengers per day.

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

History

Former split-flap display passenger information system signs used on Seoul Subway Line 2 from 1980 until replaced with flat-screen TV displays in 2005–10.
Commemorative ticket issued for the opening of the second phase of Seoul Subway Line 2 on December 23, 1982.
Fragment of an early-1980s Seoul Subway map, showing the western two-thirds of the Line 2 loop as a green line.

In 1972, then-Mayor of Seoul Koo Ja-choon [ko] (1932–1996) changed the existing plans for the Seoul Subway to better enable connectivity around the growing Seoul City and allow for development to take place across the Seoul Capital Area. 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 November 22, 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.
