Seoul Metro

Only Asia will be represented on our list of the largest metro systems in the globe in the following locations. There are 315 stations in the 1974-opened Seoul metro system. Its entire journey is 340.4 kilometers long. With more than 1.9 billion riders per year, it is regarded as one of the busiest metros in the world. By 2024, new metro stations and lines are expected to be operational.

The majority of the Seoul Metropolitan Area is served by the system, including Incheon and its satellite cities in Gyeonggi province. Regional lines on the network extend past the Seoul Metropolitan Area to rural areas more than 100 km away in western and northern Gangwon and Chungnam provinces.

Multiple systems come together to build the network to create a bigger, more cohesive system. These include the Incheon Metro lines, run by the Incheon Transit Corporation, that serve Incheon city proper; the Seoul Metro proper, which consists of Seoul Metro lines 1 through 9 and some light rail lines, that serves Seoul city proper and its surroundings; the Korail regional rail lines, that serve the greater metropolitan region and beyond; the Gimpo Goldline and the Yongin Everline that connect corners of their respective cities to the city center.
