Reliably Engineered
Light rail, metro rail, automated people movers, hydrogen rail, and electric buses — engineered with 50 years of care, and built to get you where you need to go.

What We Build
Five product lines. Woojin designs and manufactures components, systems, rolling stock, bus fleets, and operations-critical software systems that ensure reliability and maintainability.

From complete metro trains for Seoul's busiest lines to the propulsion, power, and control systems inside vehicles across Asia and North America — Woojin builds the vehicles and parts that make the systems reliable.
APM / AGT
Driverless, rubber-tired, and quiet enough to become part of the neighborhood. Woojin's K-AGT — completed in 2005, among the world's first fully automated systems — now carries passengers in Busan, Seoul, and through airports in Incheon and Jakarta.
Vehicle Refurbishment
Woojin is refurbishing 74 of LACMTA’s A650 HRVs, overhauling the exterior and interiors as well as systems, components, and software.
Hydrogen Trains
No wires. No diesel. No emissions. Developed with 25 years of railway innovation alongside Korail and the Korea Railroad Research Institute, Woojin's hydrogen fuel cell train is already running in demonstration — clean power for the lines the grid never reaches.
Electric Buses
Woojin is a major electric bus builder, with a new plant capable of manufacturing 1,500 vehicles per year. The APOLLO 900 drives itself through complex city streets on Woojin-built AI — the same engineering confidence, extended to the curb.

Built By People Who Sweat The Tolerances
Since 1974, Woojin Industrial Systems has built rail vehicles and the core electrical systems inside them — for Seoul, Busan, and operators across Asia. In the U.S. since 2011, Woojin supplies components to transit agencies nationwide and recently opened a refurbishment facility in Southern California.
We're the engineers who'd rather over-build a bogie than write a clever excuse. Come meet the team in Chicago.
