The UTM-01 and UTM-02 are South Korean medium-speed magnetic levitation (maglev) systems developed for urban and airport transit applications. Created under the guidance of the Korea Institute of Machinery and Materials (KIMM) and supported by national research programs, these models represent South Korea’s first domestically developed commercial maglev systems.

The UTM-01 (Urban Transit Maglev-01) was the first operational model and served primarily as a pilot vehicle for testing and validation. It uses electromagnetic suspension (EMS) technology, where electromagnets lift the train a few millimeters above the guideway, allowing for a smooth, quiet ride with no wheel-track contact. It was designed to operate at speeds up to 110 km/h (68 mph).

Building on the success of UTM-01, the UTM-02 is an upgraded version used in the Incheon Airport Maglev Line, which opened in 2016. This system operated on a 6.1-kilometer (3.8-mile) route with six stations, connecting Incheon International Airport to nearby destinations. The train is fully automated, driverless, and offers reliable, energy-efficient urban transit with low maintenance requirements. In 2024 the maglev service at Incheon was terminated to allow for total system overhaul. It is unclear when the system will begin to operate again.

Both UTM models feature lightweight aluminum car bodies, regenerative braking systems, and are designed for short- to medium-range urban mobility. Their development marks South Korea as one of the few countries with active, homegrown maglev systems in operation.

Together, UTM-01 and UTM-02 showcase South Korea’s commitment to sustainable, next-generation public transportation.
