The '''Chungbuk Line''' ({{Korean|hangul=충북선|hanja=忠北線}}) is a railway line serving [[North Chungcheong]] Province in [[South Korea]].  The line connects [[Jochiwon station|Jochiwon]] on the [[Gyeongbu Line]] to [[Bongyang station|Bongyang]] on the [[Jungang Line]], serving the major cities of [[Cheongju]] and [[Chungju]] ''en route.'' [[Cheongju International Airport]] is located near the rail line.

== History ==
=== Prewar ===
The first section of the line was opened by the privately owned [[Chosen Central Railway|Chōsen Central Railway]] in 1921, which became part of the [[Chosen Railway|Chōsen Railway]] (''Chōtetsu'') in 1923.<ref>[http://newslibrary.naver.com/viewer/index.nhn?articleId=1923090300209202017&edtNo=1&printCount=1&publishDate=1923-09-03&officeId=00020&pageNo=2&printNo=1101&publishType=00020 Establishment of the Chosen Railway], Dong-A Ilbo, 3 September 1923 (in Korean)</ref> Chōtetsu then continued to extend the line until 1928 to Chungju as follows:
{| class="wikitable"
|-
! Date !! Section !! Length
|-
| 1 November 1921 || [[Jochiwon station|Jochiwon]]–[[Cheongju Station|Cheongju]] || 22.7&nbsp;km
|-
| 1 May 1923 || Cheongju–Cheongan (Jeungpyeong) || 23.9&nbsp;km
|-
| 25 December 1928 || Cheongan–[[Chungju Station|Chungju]] || 47.4&nbsp;km
|}

Plans existed to continue the line from Chungju to [[Yeongwol]], but after the end of [[Korea under Japanese rule|Japanese rule]] this plan was abandoned until 1949, after which the extension was built as the [[Korail|Korean National Railroad]]'s [[Taebaek Line]].

In the November 1942 timetable, the last issued prior to the start of the [[Pacific War]], Chōtetsu operated the following schedule of local passenger services ("R" indicates that train was operated by railcar):<ref name="1942tt">Tōa Travel Co.

=== Postwar === 
Like the other private railways this line was also nationalized after the independence of Korea. The rest section of the line was opened on January 10, 1959.<ref name="lineop">{{cite web |url=http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |title=경영원칙 > 경영공시 > 영업현황 > 영업거리현황 |publisher=[[Korail]] |accessdate=2010-12-04 |url-status=dead |archiveurl=https://web.archive.org/web/20110722192217/http://info.korail.com/2007/kra/ope/ope08000/w_ope08606.jsp |archivedate=2011-07-22 }}</ref>

=== Upgrade ===<!-- [[Korea Train Express#Further upgrades of connecting conventional lines]] links here-->
The double-track construction began on October 20, 1975, and on October 17, 1980, 113.2 km between Jochiwon and Bongyang was double-tracked. During the double-track construction, some sections were relocated.<ref name="lineop"/> The entire line was electrified on 30 March 2005.<ref>{{cite web |url=http://www.epic.or.kr/cont/yearbook/download/yearbook_chap07_3.pdf |title=Electricity Almanac 2009 |publisher=Korea Electric Association |accessdate=2010-10-21 |archive-url=https://web.archive.org/web/20120314033522/http://www.epic.or.kr/cont/yearbook/download/yearbook_chap07_3.pdf |archive-date=2012-03-14 |url-status=dead }}</ref>

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 2 hours by 2020. As part of the plan, the Chungbuk Line is to be upgraded for 230&nbsp;km/h and may see [[Korea Train Express|KTX]] service.<ref name="plans2020">{{cite web |url=http://joongangdaily.joins.com/article/view.asp?aid=2925474 |title=Bullet trains coming to a town near you by 2020 |date=2010-09-02 |publisher=[[JoongAng Daily]] |accessdate=2010-10-27}}</ref> <!--But the plan is very difficult to be realized.-->

The movie ''[[Peppermint Candy]]'' was shot near Gongjeon station.
