The Janghang Line is a railway line serving South Chungcheong Province in South Korea. The line connects Cheonan (on the Gyeongbu Line) to the railway junction city of Iksan. The Janghang Line is served by frequent Saemaeul-ho and Mugunghwa-ho passenger train services between Seoul and Iksan. There is also a link from Asan station to the KTX network at Cheonan-Asan station.

History

The original Janghang Line was opened along its full length running between Cheonan and Janghang by the Chosen Gyeongnam Railway on June 1, 1922.[1]

Upgrade

The entire Janghang Line is being electrified, double-tracked, and upgraded for higher speeds with a straighter alignment. Work started in 1997 from Cheonan.[2] By the end of 2008, the new alignment was in service from Cheonan via Asan and Hongseong to Sinseong, from Jupo to Nampo, and from Ganchi to Janghang,[3] and electrification was put in service on the first 19.4 km (12.1 mi) between Cheonan and Sinchang, after Asan, on December 15, 2008.[4] The 17.1 km (10.6 mi) section near Janghang, opened in December 2007, also linked up the Janghang Line with the previously isolated Iksan-Gunsan line via a new bridge over the Geum River, with alignment built for two tracks but initially only one track was laid.[2] In 2010, the remaining sections were slated to be completed by 2018, but complete double-tracking and electrification was no longer planned on the short term due to expected low demand.[3] The realigned 14.2 km (8.8 mi) Nampo-Ganchi section, including the relocated Ungcheon station, was opened on January 5, 2021.[5] As of April 2023, the double-tracking of the Sinchang-Hongseong section was 85% completed and expected to be opened in the second half of 2024.[6] Also as of April 2023, the double-tracking of the Hongseong-Daeya section, including the 18.8 km (11.7 mi) Sinseong-Jupo realignment that was scheduled to begin construction in 2023, was in advanced planning, with a 2027 completion targeted.[6]

The Janghang Line will link up with the Seohae Line at Hongseong station. The Seohae Line will connect Hongseong to Hwaseong in Gyeonggi-do when it opens in the second half of 2024.[6] It will be connected to southern extension of the Sosa–Wonsi Line and Sinansan Line. Seohae Line will serve 250 km/h (155 mph) speed, which will dramatically reduce travel time between Seoul and Hongseong.

Sinchang-Hongseong section will be double track electrifed when Seohae Line open.[7]
