In this video, we examine the unique platform structures of Sinjungdong Station and Bucheon City Hall Station on Subway Line 7. Although both stations clearly feature island platforms, they look completely different from typical subway stations. From the center of the platform, the opposite platform is visible only, and with two connecting passageways installed, it may feel like a side platform to first-time visitors. The reason for this unusual structure is the elevated road running above the station. To avoid damage to the elevated road, the tracks were spread out to the left and right, creating a wide underground space. As a result, a unique platform structure rarely seen in other subway stations was born.
