Route map

Seoul Subway Line 5 of the Seoul Metropolitan Subway, dubbed the purple line, is a long line crossing from west to the east across the Seoul National Capital Area, South Korea. It is one of two subway lines in Seoul to cross under the Han River (the other being the Suin-Bundang Line), which is done at two points (between Mapo and Yeouinaru, and also between Gwangnaru and Cheonho). The main line runs through to Hanam Geomdansan Station while the branch line from Gangdong Station terminates at Macheon Station. In 2019, Line 5 carried an annual ridership of 334 million or about 915,000 passengers per day.^[2]

The total length of this line is 58.9 kilometres (36.6 mi). Upon opening, it was among the longest underground railway tunnels of any kind constructed. Today it is the 8th longest continuous underground subway tunnel in the world, just behind Chengdu Metro Line 6, Qingdao Metro Line 1, Guangzhou Metro Line 18, Guangzhou Metro Line 3, Moscow Metro Bolshaya Koltsevaya Line, Beijing Subway Line 10 and Beijing Subway Line 6. Line 5 is also the first subway and passenger railway line in the Korean Peninsula to directly serve an airport, when the line was extended westward to Banghwa via Gimpo International Airport in 1996.
