Seoul Metropolitan Subway
Seoul metropolitan railway system
The Seoul Metropolitan Subway (Korean: 수도권 전철) is a metropolitan railway system consisting of 24 rapid transit, light metro, commuter rail and people mover lines located in northwest South Korea. The system serves most of the Seoul Metropolitan Area including the Incheon metropolis and satellite cities in Gyeonggi province. Some regional lines in the network stretch out beyond the Seoul Metropolitan Area to rural areas in northern Chungnam province and western Gangwon Province, that lie over 100 km (62 mi) away from the capital.
The network consists of multiple systems that form a larger, coherent system. These being the Seoul Metro proper, consisting of Seoul Metro lines 1 through 9 and certain light rail lines, that serves Seoul city proper and its surroundings; Korail regional rail lines, which serve the greater metropolitan region and beyond; Incheon Metro lines, operated by Incheon Transit Corporation, that serve Incheon city proper; and miscellaneous light rail lines, such as Gimpo Goldline and Yongin Everline, that connect lower-density areas of their respective cities to the rest of the network. Most of the system is operated by three companies – Seoul Metro, Korail (Korea Railroad Corporation), and Incheon Metro – with the rest being operated by an assortment of local municipal corporations and private rail companies.
The first line of the system, Line 1, started construction in 1971 and began operations in 1974, with through-operation to Korail's suburban railways. As of 2022, the network has 331.5 km (206.0 mi) of track on lines 1–9 alone.
The majority of the rolling stock used in the system was built by Hyundai Rotem, South Korea's leading train manufacturer.
