The '''Jungang line''' ({{Korean|hangul=중앙선|hanja=中央線|lit=Central line}}) is a railway line connecting [[Cheongnyangni]] in Seoul to [[Moryang station|Moryang]] in Gyeongju in [[South Korea]], traversing central South Korea from the northwest to the southeast. It is also referred to as the rail line of the [[Seoul Metropolitan Subway]] from [[Yongsan station]] to [[Jipyeong station]]. The section from Cheongnyangni to Dodam was designated as a semi-high-speed railway.

==History==
The Jungang line was opened along its full length between Cheongnyangni and Gyeongju on April 1, 1942.<ref name="lineop">{{cite web|url=http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |title=경영원칙 > 경영공시 > 영업현황 > 영업거리현황 |publisher=[[Korail]] |access-date=2010-12-01 |url-status=dead |archive-url=https://web.archive.org/web/20110722192217/http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |archive-date=2011-07-22 }}</ref> ''Jungang'' means "central" in Korean, and describes the line's route through the mountains in the east-central part of South Korea. When Korea was [[Korea under Japanese rule|under Japanese rule]], the line was briefly known as the '''Gyeonggyeong Line''', referring to a line running between Seoul and Gyeongju.

On 1 December 1938 'Donghae Jungbu line' ([[Daegu station|Daegu]]–Haksan) was divided into three parts: [[Daegu Line]], the Gyeongygeong line and Donghae Jungbu line, which was later merged into the [[Donghae Nambu Line]].<ref>朝鮮総督府官報 (The Public Journal of the Governor-General of Korea), Shōwa No. 3558, 28 November 1938</ref> At the same time the Gyeonggyeong line was extended to the Ubo station. The southern part, Gyeonggyeong Nambu Line, was opened as follows:
{| class="wikitable"
|-
! Date !! Section !! Length
|-
| 1 December 1938 || [[Yeongcheon station|Yeongcheon]]–[[Ubo station|Ubo]] || 40.1&nbsp;km
|-
| 1 March 1940 || Ubo–Gyeongbuk Andong ([[Andong station|Andong]]) || 48.9&nbsp;km
|-
| 1 July 1941 || Gyeongbuk Andong–[[Yeongju station|Yeongju]] || 38.7&nbsp;km
|}

On the other hand, the northern part, Gyeonggyeong Bukpu Line, was constructed as follows:
{| class="wikitable"
|-
! Date !! Section !! Length
|-
| 1 April 1939 || East Gyeongseong ([[Cheongnyangni station|Cheongnyangni]])–[[Yangpyeong station (Yangpyeong)|Yangpyeong]] || 52.5&nbsp;km
|-
| 1 April 1940 || Yangpyeong–[[Wonju station|Wonju]] || 55.9&nbsp;km
|-
| 1 July 1941 || Wonju–[[Jecheon station|Jecheon]] || 46.8&nbsp;km
|}

On 1 April 1942,  the two lines were merged into the Gyeonggyeong Line with the opening of the section Jechon–Yeongju (62.3&nbsp;km).<ref>朝鮮総督府官報 (The Public Journal of the Governor-General of Korea), Shōwa No. 4536, 13 March 1942</ref> The name of the line was changed back to its present name after the end of [[World War II]].

Following the 1961 coup, the [[Supreme Council for National Reconstruction]] started South Korea's [[Five-year plans of South Korea#1962–1966|first five-year plan]], which included a construction program to complete the railway network and foster economic growth.<ref name="5yr-plan">{{cite web |url=http://www.silvernetnews.com/?inc=newsview&no=8229&s=20&ss=0&sss=0 |title=<nowiki>철마 110년, 영고의 자취 [12] 경제개발과 철도</nowiki> |language=ko |date=2010-03-20 |publisher=Silvernet News |access-date=2010-12-01}}</ref> As part of the program, in the outskirts of Seoul, a {{convert|4.9|km|mi|abbr=on}} long avoiding line was built from [[Mangu station|Mangu]] to [[Seongbuk station|Seongbuk]] on the [[Gyeongwon Line]], called the [[Mangu Line]], which opened on December 30, 1963.<ref name="5yr-plan"/>

===Phase 3: Wonju–Jecheon electrified double-track line project===
The Wonju–Jecheon electrified double-track line project was launched in 2011, connecting Seowonju station at Wonju and Bongyang station at Jecheon. Between Seowonju and Bongyang, the double-track line was to run in a new alignment, most of which would be the 25,080 metre long Musil Tunnel.<ref name="MusilTunnel"/><ref>{{cite web |url=http://www.cse.co.kr/eng/results/res_D.asp?idx=296 |title=Feasibility study and basic plan of Jungang line for double track between Wonju and Jecheon |publisher=Chunsuk Engineering |access-date=2010-10-19 |url-status=dead |archive-url=https://web.archive.org/web/20110722133253/http://www.cse.co.kr/eng/results/res_D.asp?idx=296 |archive-date=2011-07-22 }}</ref> Works on the tunnel was slated to commence in June 2011, for a planned start of service on the Wonju-Jecheon section in January 2021.

Later, the plan was redesigned to build two tunnels instead of single long tunnel, to improve safety. On June 22, 2020, construction was completed and Korean National Railway(KR) started trial running.<ref>{{Cite web|url=https://news.naver.com/main/read.nhn?mode=LSD&mid=sec&sid1=102&oid=087&aid=0000803653|title = 중앙선 원주~제천 복선전철 시운전 돌입…연말 개통}}</ref> Commercial running started on January 5, 2021.

Plans for the double-tracking of the section from Bongyang, the terminus of the Chungbuk Line, to Jecheon, have been prepared separately.<ref>{{cite web |url=http://www.cse.co.kr/eng/results/res_D.asp?idx=296 |title=Basic and detailed design of roadbed for electrified double track on Jungang line (Bongyang～Jecheon) |publisher=Chunsuk Engineering |access-date=2010-10-19 |url-status=dead |archive-url=https://web.archive.org/web/20110722133253/http://www.cse.co.kr/eng/results/res_D.asp?idx=296 |archive-date=2011-07-22 }}</ref>

===Phase 4: Dodam–Yeongcheon===

====Jecheon–Dodam section====
The Jecheon–Dodam section was double-tracked.<ref>{{cite web |url=http://www.cse.co.kr/eng/results/res_D.asp?idx=298 |title=Basic design of railway construction for double track on Jungang Line (Jecheon～Dodam) |publisher=Chunsuk Engineering |access-date=2010-10-19 |url-status=dead |archive-url=https://web.archive.org/web/20110722133721/http://www.cse.co.kr/eng/results/res_D.asp?idx=298 |archive-date=2011-07-22 }}</ref><ref>{{cite web |url=http://www.samboeng.co.kr/result/result02_19_eng.html |title=Design/Construction Package of Jungang Double Track Line (Jecheon - Dodam) |publisher=Sambo Engineering |access-date=2010-10-19 |url-status=dead |archive-url=https://web.archive.org/web/20110722134618/http://www.samboeng.co.kr/result/result02_19_eng.html |archive-date=2011-07-22 }}</ref> The rebuilt section is 17.4&nbsp;km in length, was built with a budget of 320.024 billion won, and is primarily intended to improve capacity for freight transports to a cement factory.<ref name="KRNA_2010-3">{{cite web |url=http://www.krnetwork.or.kr/service/condition/RouteMapView.do?PA_MAP_ID=12380 |title=제천~도담 복선전철 (노반,궤도 턴키공사) |publisher=Korea Rail Network Authority |access-date=2010-10-24}}</ref> The project was completed on 31 March 2011.

==== Dodam–Andong section ====
The reconstruction of the Dodam–Andong section as an electrified double-track line started in December 2013. The section includes the realignment of the Danyang–Yeongju section, which opened as a single-track section on 13 December 2020. The Yeongju–Danchon section, another re-alignment, opened as single-track on 17 December 2020. The electrified and double-tracked Dodam–Danyang section opened in 5 January 2021, the second track on the Danyang–Yeongju section opened on 30 June 2022, finally the second track on the Yeongju–Danchon section and the electrified and double-tracked Danchon–Andong section opened on 28 July 2022. Operation of the entire section at the maximum line speed started only in December 2023.

==== Andong–Yeongcheon section ====
This section was originally planned to open in the summer 2022 as electrified single-track line, prepared for later double-tracking. In December 2021, the decision was made to complete the section as a double-track line, with opening planned in Late 2024. Construction started in December 2022 and completed on 20 December 2024. After 23 years, the whole Jungang Line became fully double-tracked and electrified.

=== Phase 5: Yeongcheon–Singyeongju ===
Electrification and doubling in this section were completed on December 28, 2021.<ref>{{cite news|url=https://www.kukinews.com/newsView/kuk202112280155|first=Jaeyong|last=choi|title=Era of electrified double-track railway opens in Daegu, Jungang, Donghaenambu line after 100 years|date=2021-12-28|access-date=2021-12-30|language=ko}}</ref>

==Services==

=== KTX service ===
KTX service was launched on 5 January 2021. Since Jungang Line is not a dedicated high-speed line, the new rolling-stock [[KTX-Eum]] was adopted.<ref>{{cite web|title=S.

===Regular rail service===
Before the [[Korea Train Express|KTX]] era, trans-Korean Tongil-ho trains were in operation on the Jungang and Donghae Nambu lines, providing a 12-hour train journey from Seoul to Busan.

The entire line is served by cross-country [[Mugunghwa-ho]] trains, which are most frequent until Jecheon, where many trains continue east on the Taebaek Line. As of October 2010, the travel time from Cheongnyangni in Seoul is a minimum of 1 hour 18 minutes to Wonju, 2 hours 2 minutes to Jecheon, around 3 hours to Yeongju, 5 hours 22 minutes to Yeongcheon, and 6 hours 8 minutes to Gyeongju. Some trains continue to Bujeon station in Busan, with a total travel time of 8 hours by day and 20 minutes shorter by night.<ref name="booking">{{cite web|url=http://www.korail.com/en/rv/pr21100/w_pr21110.jsp |title=Booking |publisher=[[Korail]] |access-date=2010-10-28 |url-status=dead |archive-url=https://web.archive.org/web/20110713164814/http://www.korail.com/en/rv/pr21100/w_pr21110.jsp |archive-date=13 July 2011 }}</ref> After 20 December 2024, the [[Mugunghwa-ho]] were replaced by ITX-Maum.

===Seoul Metropolitan Subway===
{{main|Gyeongui–Jungang Line}}
Commuter rail service was launched on Jungang line (fully integrated with the Seoul Metropolitan Subway) as the upgrading of the line progressed.<ref name="irj-future"/><ref name="rgi-korailplans"/> The service started on December 16, 2005, connecting parts of the [[Gyeongwon Line]] (from [[Yongsan station|Yongsan]] to [[Hoegi station]]) and the Jungang line (from Hoegi to Deokso) under the interim name '''Yongsan–Deokso Line'''.

An extension to [[Paldang station]] on December 27, 2007, brought the official renaming of the service to '''Jungang line''', although the line actually incorporates parts of ''both'' Gyeongwon and Jungang lines. In December 2008, the service was extended to Guksu station, and an [[express train]] service was launched, operating twice a day during morning [[commuting]] hours. The express trains ran westward only, from Yangpyeong to Yongsan. The service was finally extended to [[Yongmun station (Yangpyeong)|Yongmun station]] in [[Yangpyeong|Yangpyeong County]] on December 23, 2009.<ref name="KRNA_2010-1"/>

The western terminus was Yongsan station ever since the opening of the line. However, with the completion of [[Gyeongui Line]] extension to Yongsan on December 27, 2014, both the Jungang and Gyeongui lines were combined into the "[[Gyeongui-Jungang Line]]," and trains now run to [[Munsan station]] near the North Korean border.<ref>{{Cite web | title =[수도권II] "경의선 효창정거장 부지 220m 때문에…" | publisher =Chosun | date =2011-08-25 | url =http://news.chosun.com/site/data/html_dir/2011/08/24/2011082402671.html | format = (Korean Language) | access-date = 15 July 2012}}</ref>
