Commuter Train (South Korea)

The Commuter Train (previously called Tongil-ho) was a class of short-run commuter trains operated by Korail, the national railroad of South Korea. They operated once or twice daily in each direction, along a few tens of kilometers of track. They provided an important function for many smaller rural communities (including suburbs around Seoul), which often lack good transit connections. Commuter Train operations on the Gyeongwon line was temporarily suspended its operation on April 1, 2019, due to the construction and partial electrification of the line for the Soyosan-Yeoncheon extension of Seoul Subway Line 1. They were permanently suspended on December 16, 2023, after the opening of the Yeoncheon extension, and due to the old age of CDC trains. This effectively ended regular train service north of Yeoncheon Station, with the provincial government of Cheolwon lodging a complaint. Commuter trains last operated on the Gwangju Line in Gwangju between GwangjuSongjeong and Gwangju station, from January 1, 2020, until December 17, 2023, permanently being phased out due to the old age of CDC trains.
