There are many types of trains in Seoul but they are generally similar to each other. All Seoul Metropolitan Subway rolling stock follow the Japanese-style commuter/subway train interior layout of all-longitudinal seating with luggage racks above seats (except Line 9, Shinbundang Line and light rail lines). Typically, train cars have four pairs of doors on each side. In between the doors are rows of either cushioned or non-cushioned seats for 7 people (6 on newer trains), except for the outer ends of each wagon where there are smaller rows of seats for 3 people, marked for the use by the elderly, disabled passengers, and pregnant women.

This list focuses primarily on trains that run on the 9 urban subway lines in Seoul, the wide-area commuter rail lines integrated into the Seoul Metropolitan Subway, and the AREX airport railroad. The list does not, however, include rolling stock used on the Incheon Subway and light metro systems such as the U Line or EverLine.
