Donghae Line

The Donghae Line (Korean: 동해선) is a railway line connecting Busanjin station to Samcheok station in South Korea. The literal meaning of its name, the "East Sea Line," reflects its position along the nation's East coast. It merged with the Donghae Nambu Line on December 30, 2016, and will merge with the Donghae Bukbu Line.

On January 26, 2018, the East Sea Line was partially extended to Yeongdeok Station, and on January 1, 2025, the line between Yeongdeok Station and Samcheok Station was opened.
