The GTX-A, officially Metropolitan Area Rapid Transit Line A, is a higher-speed commuter railway line operating in two sections in Seoul, South Korea.
Groundbreaking for GTX Line A was held on December 27, 2018, with service initially expected to commence in 2023. [3] However, the project has been officially delayed due to land compensation issues and the discovery of archaeological ruins dating from the Joseon period. [4]
The line currently runs in two separate sections - Dongtan to Suseo and Unjeongjungang to Seoul Station. Suseo, Seongnam, and Dongtan stations were opened on March 30, 2024, with Guseong Station opening later on June 29, 2024. [5] [6] The section between Unjeongjungang and Seoul Station opened on December 28, 2024. [7] The connection between Seoul Station and Suseo is anticipated to open in August 2026. [8] Samseong Station has been further delayed and will not open until 2028. [9]
Approximately 30 km (19 mi) of the line are expected to share the same rail as the SRT, and an additional 9 km (5.6 mi) towards the western end of the route are expected to be completely underground. [10] Trains operate at around three to four services per hour in each direction in the southern section with anywhere between 15 to 30 minutes between services. [11] Meanwhile, the northern section operates at six services per hour per direction with ten minutes between services. [11]
Each GTX-A train has a capacity of 1,090 passengers. [12]

Plans for a Line D were announced in 2021 by the previous government. However, the proposed route faced a lot of opposition, and has not been approved yet. The new government of Yoon Suk-yeol has pledged to build three new lines (Lines D, E and F), for which the routes have not been decided yet, but which would likely include plans for a longer Line D than the one announced by the previous government. Plans for a Line G and H that will expand to the northern and southwestern regions of Gyeonggi Province have also been announced. [15]

Critics argue that GTX project would increase the social and economic centripetal force towards Seoul leading to increased primacy and the collapse of other provincial cities. [16]
The Seoul Metropolitan Subway is a metropolitan railway system consisting of 23 rapid transit, light metro, commuter rail and people mover lines located in northwest South Korea. The system serves most of the Seoul Metropolitan Area including the Incheon metropolis and satellite cities in Gyeonggi province. Some regional lines in the network stretch out beyond the Seoul Metropolitan Area to rural areas in northern Chungnam province and western Gangwon Province, that lie over 100 km (62 mi) away from the capital.
The Incheon Subway is a subway system serving the South Korean city of Incheon. The system is operated by Incheon Transit Corporation, and is part of the greater Seoul Metropolitan Subway.
Sindorim station is a station on Seoul Subway Line 1 and Line 2 (underground). It is also the southeastern terminus of Line 2's Sinjeong Branch to Kkachisan. The station is located at the northern edge of Sindorim-dong, Guro-gu, Seoul, on the border with Yeongdeungpo-gu.
SuseoStation is a railroad station on the Suin–Bundang Line and Line 3 of the Seoul Metropolitan Subway. The station is in the Suseo neighborhood of the Gangnam District in Seoul, South Korea. Prior to the Line 3 extension to Ogeum station in 2010, Suseo Station was the southeastern terminus of Line 3. Along with Yangjae station, Suseo Station serves as an important transfer point between Line 3 and buses from/to southern cities such as Seongnam, Yongin, and Suwon.
Yeonsinnae station is a station on Seoul Subway Line 3 and Seoul Subway Line 6, on the northwest side of Seoul in the urban area of Eunpyeong-gu. Although Yeonsinnae Station had a corresponding hanja name (延新內), this name was deemed incorrect and dropped in May 2001.
The Gyeongbu high-speed railway, also known as Gyeongbu HSR, is South Korea's first high-speed rail line from Seoul to Busan. KTX high-speed trains operate three sections of the line: on 1 April 2004, the first between a junction near Geumcheon-gu Office station, Seoul and a junction at Daejeonjochajang station north of Daejeon, and a second between a junction at Okcheon station, southeast of Daejeon, and a junction near Jicheon station, north of Daegu entered service; then on 1 November 2010, the third section, between a junction west of Daegu and Busan became operational. The missing gaps across the urban areas of Daejeon and Daegu were in construction for an expected opening in 2014, separate tracks into Seoul Station were also planned. The temporary ends of the three sections were connected to the parallel conventional Gyeongbu Line by tracks that will serve as interconnector branches upon the completion of the entire line. On 1 August 2015, construction on urban areas of Daejeon and Daegu were completed; all the sections of HSR line were connected.
Daegok station (Korean: 대곡역) is a station on Seoul Subway Line 3, the Gyeongui–Jungang Line and the Seohae Line. It is located in Goyang, Gyeonggi Province, South Korea. It is mainly used as a transfer station between the three lines rather than as an actual enter-and-exit stop, as the station is located in the midst of farmland with very little local resident demand.
The Sinansan Line is the tentative name of a commuter rail line that will eventually link Cheongnyangni station with western Gyeonggi province, passing through key areas of the Seoul metropolitan area, including Yeouido, Yeongdeungpo and Gwangmyeong station.
The Seohae Line (Korean: 서해선) is a dual-track, electrified rail line in western Gyeonggi-do and Seoul, South Korea. The Seohae Line is being built in four sections simultaneously. The line runs 47 km (29 mi) south from Ilsan in Goyang City, crosses the Han River, passes Gimpo Airport, Sosa, Siheung, and ends in Wonsi in Ansan. There is a transfer to different lines at Daegok, Neunggok, Gimpo Int'l Airport, Bucheon Stadium, Sosa and Choji. There are currently 21 stations (Ilsan-Wonsi). The line is operated by Korail, but the stations between Sosa and Wonsi are managed by SEO HAE RAIL CO.,LTD., which is a subsidiary of Seoul Metro. The infrastructure is also owned by Korail so the line runs on the left like the rest of the South Korean mainline railway network.
The Ui LRT, referred to as the Ui-Sinseol LRT or Ui-Sinseol Line (우이신설선) in Korean, is a light metro which is part of Seoul Metropolitan Subway. It is a fully underground 11.4 km (7.1 mi) Light Rapid Transit line from Ui-dong to Sinseol-dong in northern Seoul which opened on September 2, 2017. The line, which is expected to carry 110,000 passengers a day, has 13 stations. It connects to Line 4 at Sungshin Women's University, Line 6 at Bomun and Lines 1 & 2 at Sinseol-dong. The last (northernmost) station is in Ui-dong, hence the name of the line. In 2019, the line carried 27 million passengers or about 75,000 people per day.
The Super Rapid Train, often known as SRT, is a high-speed rail service operated by SR Corporation. The service starts at Suseo station in southeast Seoul and terminates at either Busan station or Mokpo station.
High-speed rail service in South Korea began with the construction of a high-speed line from Seoul to Busan in 1992, and was inspired by Japan's Shinkansen. The first commercial high-speed rail service was launched on 1 April 2004. Currently, South Korea hosts two high-speed rail operators: Korea Train eXpress (KTX) and Super Rapid Train (SRT).
Guseong Station is a subway station of the Suin–Bundang Line, the commuter subway line of Korail and the national railway of South Korea, as well as the GTX-A.
Dongtan (Korean: 동탄) is a township in Hwaseong, Gyeonggi, South Korea, with many shops and restaurants. There are also 4 residential skyscrapers of 70-80 floors. They are collectively called Metapolis and contain a shopping mall. Dongtan also has the Suseo–Pyeongtaek high-speed railway (SRT) that goes from Suseo station to Jije station. The subway is 52.3 km (32.5 mi) long as the third longest in the world. It also has the longest tunnel for a subway that goes at a speed of 300 km/h (190 mph).

The Yulhyeon Tunnel is a railway tunnel in South Korea, which opened in 9 December 2016, and is currently the world's fourth longest railway tunnel at 50.3 kilometres (31.3 mi). The tunnel, which consists of a double-track tube, is part of the 61.1-kilometre (38.0 mi) Suseo–Pyeongtaek high-speed railway and GTX-A that connects Suseo station in the southeastern part of Seoul with the Gyeongbu high-speed railway. The threading into the older high-speed line is in the south of the city of Pyeongtaek. The tunnel itself takes up about 82% of the total new line. The Yulhyeon Tunnel was built using the New Austrian tunnelling method (NATM) and is designed for a maximum speed of 300 km/h (186 mph). The average cruising speed is about 240 km/h (149 mph) due to the intermediate stop at Dongtan Station in the southern part of the tunnel.
The Suin–Bundang Line is a commuter rail service of the Seoul Metropolitan Subway system, operating on trackage from the Suin Line and the Bundang Line. Operation began on September 12, 2020.
The Suseo–Pyeongtaek high-speed railway, also known as Suseo–Pyeongtaek HSR, is a high-speed rail line from Suseo station in southeast Seoul to a junction with the existing Gyeongbu high-speed railway in South Korea. The line was built to ensure southeast Seoul and southern Gyeonggi-do have high-speed rail connections.
