The Donghae Line ({{Korean|hangul=동해선}}) is a railway line connecting Busanjin station to Samcheok station in South Korea. The literal meaning of its name, the "East Sea Line," reflects its position along the nation's East coast. It merged with the Donghae Nambu Line on December 30, 2016, and will merge with the Donghae Bukbu Line.

In January 26, 2018, the East Sea Line was partially extended to Yeongdeok Station, and on January 1, 2025, the line between Yeongdeok Station and Samcheok Station was opened.

Stations

Major stations along the line include (in order):

Bujeon station, terminal station of the line and terminus of the Bujeon Line
BEXCO station, where the G-Star gaming event is held

Services

===KTX===

Plans foresee direct KTX high-speed train service from Seoul to Pohang and Ulsan after the completion of the upgrades. From 2015, direct KTX trains are to reach Pohang from Seoul in 1 hour 50 minutes, cutting 33 minutes from the travel time with transfer at Gyeongju.{{cite web|title=KORAIL to launch Seoul-Pohang KTX|url=https://www.koreaherald.com/article/439044|publisher=The Korea Herald|date=2015-03-31}} Under the government's 2010 strategic plan for 2020, the entire line may see KTX service.{{cite web |date=2010-09-02 |title=Bullet trains coming to a town near you by 2020 |url=http://joongangdaily.joins.com/article/view.asp?aid=2925474 |url-status=dead |archive-url=https://web.archive.org/web/20150824170833/http://koreajoongangdaily.joins.com/news/article/article.aspx?aid=2925474 |archive-date=August 24, 2015 |access-date=2010-10-27 |publisher=JoongAng Daily}}

=Pohang–Samcheok extension=

At the time of thawing relations between South and North Korea, when the cross-border section of the Donghae Bukbu Line was reopened in 2007, the South Korean government considered the construction of a railway for freight traffic all along the east coast to the North Korean border.{{cite journal |url=http://www.irail.net/webzine/krt/20071008/15356_cf_171_KRT_9.pdf |title=Trans-Korean Railway |journal=Korean Rail Technology (English) |volume=9 |pages=09–11 |date=September 2007 |access-date=2010-11-04 |archive-date=2018-07-14 |archive-url=https://web.archive.org/web/20180714221847/http://www.irail.net/webzine/krt/20071008/15356_cf_171_KRT_9.pdf |url-status=usurped }}{{cite web |url=http://www.railwaygazette.com/news/single-view/view/10/south-koreas-growing-network.html |title=South Korea's growing network |date=2008-09-08 |publisher=Railway Gazette International |access-date=2010-10-28 |archive-date=2012-12-05 |archive-url=https://archive.today/20121205072403/http://www.railwaygazette.com/news/single-view/view/10/south-koreas-growing-network.html |url-status=dead }} As part of the corridor, a new single-track, non-electrified line for {{convert|150|km/h|abbr=on}} would connect Pohang and Samcheok, the end of a branch of the Yeongdong Line.{{cite web |url=http://www.railjournal.com/altfeature1.shtml |title=Korea's railways face a bright future |date=2008-07-01 |publisher=International Railway Journal |archive-url=https://web.archive.org/web/20090416195911/http://www.railjournal.com/altfeature1.shtml |archive-date=2009-04-16 |access-date=2010-10-28 |url-status=dead }} new line is to connect to the existing railhead at Samcheok.
