The Shinbundang Line (aka Sinbundang Line; Korean: 신분당선 (literally, New Bundang Line)) or DX Line is a 31 km long line of the Seoul Metropolitan Subway. It is the world's fifth[1] subway to run completely driverless and the second completely driverless metro line to open in South Korea, after Busan Subway Line 4. It connects Gangnam Station and Gwanggyo Station in 37 minutes, a feat achieved by being the first line to operate South Korea's next-generation subway car travelling at over 90 km/h, with the fastest average speed of any subway in the country.[2][3]

The initial route opened in October 2011 passed through 6 stations intersecting with three existing lines at Gangnam Station (Line 2), Yangjae Station (Line 3), and Jeongja Station (Bundang Line). Phase 2 opened on 30 January 2016 added 6 stations to the south, extending the line to serve Yongin's Suji-gu and Suwon's Gwanggyo New City. Construction for Phase 3's extension northwards to Sinsa Station is planned in 2016, with opening slated for 2021.[4]

The SBL Line signal system is based on state-of-the-art communications-based train control (CBTC) technology, utilizing two-way digital radio communications between intelligent trains, and wayside equipment, and a network of ATS/ATO computers designed for very high system reliability and availability. Construction started in mid-2005, with Phase 1 opening on 28 October 2011.

Gwanggyo Jungang (Ajou Univ.) Station will open its underground bus transfer station on 22 February 2016, where screen doors are installed on bus platforms so bus riders from all over Suwon can transfer to the subway directly.[5]

The price to ride the Shinbundang Line is higher than standard fare for the rest of the Seoul subway system. The minimum cost is currently 2,150 won to ride (base subway fare of 1250 won along with a 900 Won surcharge for using the line). If one crosses Jeongja Station, 300 won is charged on top of the 900 won extra charge, although a cashback is offered to frequent riders between Pangyo Station and Dongcheon/Suji-gu Office Station.[6]

Phase 1 alleviated some of the traffic from inner Seoul to Bundang which is mainly residential and within the Seoul Capital Area. Phase 1 was 17.3 km and intersects with several subway lines in south-eastern Seoul as well as with the Bundang Line. Travel from one end to the other was 16 minutes. Construction lasted for roughly six years starting in mid-2005 and ended at the end of October, 2011. Total cost between public and private sectors was estimated at 1.169 trillion won.[7][8][9]

Phase 2 was primarily designed to ease heavy traffic between Yongin's Suji-gu and Bundang/Seoul, as Suji-gu was not a planned city like Bundang but abruptly and organically developed with large apartment complexes. As a result, Suji-gu is even more residential than Bundang, resulting in heavy traffic in connecting roads. The other aim was to connect the newly planned city of Gwanggyo rapidly to Seoul. Because of the investors and owners of Phase 1 and 2 being different, a 300 won extra charge was added on top of the 900 won extra charge if riders crossed Jeongja Station. Residents of Suji and Gwanggyo criticized the fare discrimination, despite a cashback being offered to frequent riders between Pangyo Station and Dongcheon/Suji-gu Office Station (200 won for Dongcheon and 100 won for Suji-gu Office).[6] The mayor of Yongin and Suwon, along with officials from Gyeonggi-do asked the Ministry of Land, Infrastructure and Transport to lower the fares, which announced that it is trying to cut the fare by using low interest rate loans but it would take at least a year for it to be finalized.[10]

Phase 3 was originally planned to extend the northern section of the line to Yongsan Station but due to the extension from Sinsa to Yongsan potentially sharing tracks with the GTX A line towards Ilsan, construction will initially begin in 2016 between Sinsa and Gangnam only, slated for opening in 2021.[4]

Phase 4 extension to Suwon's Homaesil and Hwaseo Station is currently undergoing economic viability assessments by the government, with Suwon City saying that results should be positive when it comes out.[11]

There are proposals in Gyeonggi-do about making the Gwanggyojungang Station a transfer to EverLine.[12]

Operation[edit]

From Gangnam Station, trains are available from 5:30am until 24:50 midnight on weekdays, cut to 11:48pm on weekends and public holidays. However, the last train to Gwanggyo departs at 24:26 on weekdays, cut to 23:48 on weekends, with the remainder going until Jeongja Station only.

The trains are automated and run every 2.5 minutes during peak times to 8 minutes during off-peak hours. Platforms can accommodate 10-car trains at 200 meters but initially 6-car trains will be used.[9][13][14]
