There are many types of trains in Seoul but they are generally similar to each other. 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.

Features Emergency procedures

Each train has at least one fire extinguisher and options for opening the door in an emergency. A SOS phone is placed in most cars operated by the Seoul Metropolitan Rapid Transit Corporation, and all new rolling stock.

Help for English Speakers

All trains in Seoul have both English and Korean announcements regarding each train stop. In addition, a map displays their names in both Korean and Latin characters. Many trains also have a LED display above a door or in the middle of the train car that displays information in Korean and English. However, many destination signs from the sides of the train have been removed due to their reduced visibility with the installation of platform screen doors. Some of the newest trains feature LCD screens above the doors or the middle of the train that display short commercials and station information.

Fleet Seoul Metro & Korail All cars are 19.5 meters in length, 3.12 meters in width, and 3.8 meters in height. (63.98 feet in length, 10.24 feet in width, and 12.47 feet in height.) Newer trains operated by Seoul Metro are usually given the same variables because they are intended to replace older trains.

All trains on Lines 5-8 are equipped with an ATO (Automatic Train Operation) systems. As a backup, there is always a driver on board in case of a failure in the ATO system.
