The '''Suseo–Pyeongtaek high-speed railway''' (formerly known as Sudogwon HSR Line),<ref>{{cite web|url=http://www.molit.go.kr/USR/BORD0201/m_69/DTL.jsp?mode=view&idx=228142|title=MOLIT official announcement #2016-732|publisher=[[Ministry of Land, Infrastructure and Transport (South Korea)|MOLIT]]|access-date=2021-01-07|date=2016-11-10}}</ref> 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 (or Gangnam area) and southern [[Gyeonggi-do]] have high-speed rail connections.

==History==
===Origins of the project===
{{See also|Honam high-speed railway}}
While South Korea's first high-speed line, the Gyeongbu high-speed railway (Gyeongbu HSR) was in construction between Seoul and [[Busan]], the government considered a second line from Seoul to Mokpo, the Honam high-speed railway (Honam HSR). The first feasibility study in 2003 came to the conclusion that the construction of a full line is not justified by demand, and proposed a two-stage construction.<ref name="honamplans">{{cite journal |first=Il-Ho |last=Chung |title=Plan for Honam High-Speed Railway |journal=Space and Environment |volume=25 |date=July 2006 |pages=6–8 |publisher=Korean Research Institute for Human Settlements |url=http://168.126.177.50/pub/docu/en/AD/BE/ADBE2006BAC/ADBE-2006-BAC-003.PDF |access-date=2010-08-29 |url-status=dead |archive-url=https://web.archive.org/web/20120311002058/http://168.126.177.50/pub/docu/en/AD/BE/ADBE2006BAC/ADBE-2006-BAC-003.PDF |archive-date=2012-03-11 }}</ref> The first stage, to be realised by 2015, would involve two branches from the Gyeongbu HSR, one of which would lead to a second Seoul terminus at Suseo in the southeast part of the city.<ref name="honamplans"/> However, in plans made official in August 2006,<ref name="tci-honam-money">{{cite web |url=http://english.chosun.com/site/data/html_dir/2006/08/23/2006082361031.html |title=High-Speed Train to Extend Southwest Route |date=2006-08-23 |publisher=[[The Chosun Ilbo]] |access-date=2010-08-28}}</ref> the Suseo branch was no longer included.<ref name="honamplans"/>

The Suseo branch was re-launched as a separate project, the Metropolitan Area high-speed railway (initially the Suseo high-speed railway), on June 1, 2008, to improve traffic connections to two new housing development areas situated along the line in [[New Dongtan City|Dongtan]].<ref name="hk_relaunch">{{cite web |url=http://www.hankyung.com/news/app/newsview.php?aid=2008060193681&sid=0106&nid=006&ltype=1 |script-title=ko:동탄~수서 12분 걸리는 고속철 만든다 |language=ko |date=2008-06-01 |publisher=[[Korea Economic Daily|Hankyung]] |access-date=2010-11-11}}</ref>

===Planning stage===
{{see also|Yulhyeon Tunnel}}
Preliminary plans foresaw a {{convert|60.7|km|mi|abbr=on}} long line from Suseo to the junction with the Gyeongbu HSR near [[Pyeongtaek]], and three new KTX stations at Suseo, Dongtan and Pyeongtaek, with the last one situated after the junction on the Gyeongbu HSR.<ref name="hk_relaunch"/>  The line was to run in a tunnel at a depth of {{convert|50|m|ft|abbr=on}} between Suseo and Dongtan, and construction with a budget of 4.18 trillion [[South Korean won]] was foreseen to be complete in 2015.<ref name="hk_relaunch"/>  The travel time from Suseo to Dongtan was foreseen to be 12 minutes.<ref name="hk_relaunch"/>  The target date for finishing the line was later moved ahead to 2014.<ref name="suseoannounce">{{cite web |url=http://joongangdaily.joins.com/article/view.asp?aid=2914691 |title=KTX ready for big expansion in 2010 |date=2009-12-31 |publisher=[[Korea JoongAng Daily]] |access-date=2010-08-29}}</ref>

The basic design was completed on April 28, 2010.<ref name=":0">{{Cite news|url=http://news.mk.co.kr/newsRead.php?year=2010&no=218420|title=수서~평택 고속철도 61km 구간 설계착수|work=[[Maeil Business Newspaper]]|access-date=2018-06-14|language=ko}}</ref> The planned length of the line changed to {{convert|61.1|km|mi|abbr=on}}, and planned stations reduced to two, at Suseo and Dongtan.<ref name=":0" /> The government set out a timeplan, according to which detailed design was to commence immediately, and construction was to take place from the second half of 2011 until the end of 2014.<ref name="mk_basicdesign">{{cite web|url=http://news.mk.co.kr/outside/view.php?year=2010&no=217310|archive-url=https://archive.today/20120716045722/http://news.mk.co.kr/outside/view.php?year=2010&no=217310|url-status=dead|archive-date=2012-07-16|date=2010-04-28|publisher=[[Maeil Business Newspaper]]|language=ko|script-title=ko:수도권 고속철 수서~평택 설계 착수|access-date=2010-11-11}}</ref> The first detailed design contracts were awarded in September 2010.<ref name="hk_design-tenders">{{cite web |url=http://www.hankyung.com/news/app/newsview.php?aid=2010090800261&intype=1 |title=수서~평택 고속철도 수주...현대산업개발·GS건설 |language=ko |date=2010-09-08 |publisher=[[Korea Economic Daily|Hankyung]] |access-date=2010-11-11}}</ref>

Once the line is completed, the expected travel time will be 1 hour 59 minutes from Suseo to Busan via the Gyeongbu HSR, and 1 hour 49 minutes from Suseo to Mokpo via the Honam HSR.<ref name="hk_design-tenders"/>

===Longer term plans===
On September 1, 2010, the South Korean government announced a strategic plan to reduce travel times from Seoul to 95% of the country to under two hours by 2020.<ref name="plans2020">{{cite web |url=https://koreajoongangdaily.joins.com/2010/09/01/socialAffairs/Bullet-trains-coming-to-a-town-near-you-by-2020/2925474.html|title=Bullet trains coming to a town near you by 2020|date=September 2, 2010|publisher=[[JoongAng Daily]]|access-date=October 27, 2010}}</ref> As part of the plan, tracks for up to {{convert|230|km/h|mph|abbr=on|0}} are to connect Suseo and [[Yongsan Station|Yongsan]] in central Seoul.<ref name="plans2020"/>

In November 2020, [[Ministry of Land, Infrastructure and Transport (South Korea)|MOLIT]] announced extension of Suseo–Pyeongtaek high-speed railway to [[Uijeongbu]]. However, no completion date for the extension was announced.<ref>{{cite web |url=https://news.mt.co.kr/mtview.php?no=2020120213225140222|title=[단독]SRT 의정부 연장...정부 '오락가락'에 수십억 혈세낭비 |language=ko |date=2020-12-03 |publisher=Money Today |access-date=2021-01-06}}</ref>
