The Ansan Line is part of Line 4 and is served by commuter electric trains. From Geumjeong Station to Surisan Station, an urban landscape unfolds; beyond Surisan Station, the scenery shifts to a rural landscape; and past Sangnoksu Station, the urban landscape returns. Another characteristic of Ansan Station is that it has a large number of foreign passengers. The replacement with new trains has already been fully completed.
