Seoul Subway Line 2

History

In 1972, then-Mayor of Seoul (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 Metropolitan Area. Line 2 was built in 1978–84 together with the Seongsu Branch (the second Sinjeong Branch was built 1989–95). Dangsan Railway Bridge was closed for reconstruction in 1996 and reopened November 22, 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. During this period, the inner loop only ran to Dangsan Station, and the outer loop only ran to either Hongik University Station or Hapjeong Station.

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.

Facilities

In December 2010 the line is recorded as having the highest WiFi data consumption in the Seoul Metropolitan area. It averaged 2.56 times more than the other 14 subway lines fitted with WiFi service zones.

In 2011, retailer Homeplus opened the world's first virtual supermarket at Seolleung station, where smartphone users can photograph the bar code of life-size pictures of 500 items of food, toiletries, electronics etc. on the walls and platform screen doors, for delivery the same day.

Extension

There is a possible extension currently in the conception stage to extend the Sinjeong Branch to 3.7 km to Gayang Station on Line 9. The path would include a new station named Gangseo-gu Office in between Kkachisan and Gayang.

Rolling stock

Five generations of Seoul Metro 2000 series trains have been used on Seoul Subway Line 2. As of , only third, fourth and fifth batch 2000 series trains are in operation (manufactured by Hyundai Rotem and Dawonsys respectively), since all first (MELCO thyristor chopper control) and second batch (GEC Traction/Alstom thyristor chopper control) trains have been retired between 2008 and 2023. All trains are stored and maintained at Sindap Depot on the Seongsu Branch and Sinjeong Depot on the Sinjeong Branch.
