Oksu Station is a railway interchange station on the Line 3 and the Gyeongui–Jungang Line (this section formerly part of Line 1 until 2007). It was opened in 1985 and is located near the confluence of the Han and Jungnang Rivers.
The Line 3 platforms are one of four aboveground stations on Line 3 (The others are Jichuk, Wondang, and Daegok). The Gyeongui–Jungang line part was recently renovated with a glass-covered top which lets in sunlight. It has a view of the Han River and is often seen in movies and advertisements. The 2011 manhwa webtoon Oksu Station Ghost and its 2022 movie adaptation are set at the Line 3 platforms.
