Changdong Station in Seoul is a transfer station where Line 1 and Line 4 meet. Near Exit 1 are Hanaro Mart and Platform Changdong 61, and E-Mart sits close to Exit 2. Construction on the privately funded station building has been halted for a long time, leaving the Line 1 platform narrow and without screen doors. The transfer route between Line 1 and Line 4 is still poorly organized, making it confusing and cluttered.
