Sinseol-dong Station

Sinseol-dong Station is a station on the Seoul Subway Line 1 and the Seongsu Branch of Seoul Subway Line 2. There is a piece of track that connects the Line 1 and Line 2 stations, and Line 1 trains belonging to Seoul Metro are serviced at the Gunja Train Depot behind Yongdap Station using this connective track. There is a 'secret' unused platform on the B3 floor of this station; this used to be the original Line 2 platform. However, due to intermittent flooding, this platform was closed off, and a new platform on the B2 floor serves as the current Line 2 station.
