The Gyeonggang line and Gangneung station opened at December 22, 2017. The KTX-Sancheon train started stopping here. However, the Mugunghwa-ho trains terminated at Jeongdongjin station before July 18, 2018. This is because there were many KTX-Sancheon because of the 2018 Winter Olympics in Pyeongchang County.
