The Gangneung Line and Gangneung station opened at December 22, 2017. The KTX-Sancheon (now KTX-Eum) trains started stopping here. However, the Mugunghwa-ho trains terminated at Jeongdongjin station before July 18, 2018, before all of the Mugunghwa trains that terminated at Jeongdongjin got cut back to Donghae. This is because there were many KTX-Sancheon because of the 2018 Winter Olympics in Pyeongchang County.
