Woojin Industrial Systems

Woojin Industrial Systems, also known in Korean as Woojin Sanjeon, is a South Korean manufacturer focused on rail transportation equipment and related electrical technologies. Founded in 1974, the company develops and supplies rolling stock, propulsion and monitoring systems, auxiliary power equipment, driver-cabin devices, and other train subsystems. Its portfolio spans conventional electric multiple units, diesel multiple units, automated peoplemovers, rubber-tyred metro vehicles, monorails, trams, and battery-powered electric buses. The company has participated in numerous South Korean urban-rail projects. Its rolling-stock references include train series used by Korail, Seoul Metro, Busan Metro, and the Incheon International Airport automated peoplemover. It has also supplied or supported equipment for specialized systems such as the Daegu Metro straddle-beam monorail and Seoul's Sillim Line. In addition to complete or substantially integrated vehicles, Woojin supplies core railway electronics. Examples include propulsion and monitoring upgrades for Manila Light Rail Transit LRTA 2000-class trains and static-inverter upgrades for Taiwan Railway EMU500 trainsets, the latter undertaken as a subcontractor to Mitsubishi Electric. Woojin has also built an international refurbishment and systems-support business. Its projects have included refurbishment of Malaysia's KTM Class 83 trainsets and work for transit authorities in the United States. In 2011, the company established a local corporation and production plant in Los Angeles. It subsequently supplied broadcasting display devices, driver-cabin equipment, and auxiliary power devices to transportation agencies in Washington, Oregon, Massachusetts, and Utah. In 2024, Los Angeles Metro selected Woojin to refurbish its Breda A650 rail cars, with the work associated with preparing the fleet for the 2028 Summer Olympics. The company entered the electric-bus sector in 2016. Its Apollo line consists of plug-in, low-floor electric buses in several size classes, including the Apollo 700, 900, 1100, and 1200. The series was publicly introduced at the 2017 Daegu International Future Auto Expo and is produced at the Ochang plant in Cheongju. Woojin expanded this business with an electric-bus smart factory in Gimcheon, North Gyeongsang Province. The facility was completed in 2024, began mass production during the second half of that year, and was described as having annual capacity of 1,500 buses. The company's activities therefore combine rail-vehicle manufacturing, transit-vehicle refurbishment, railway electrical engineering, and zero-emission bus production. Available reference material does not establish a separate consumer-facing sub-brand structure, public listing status, current executive roster, or a corporate website.

Woojin Industrial Systems was founded in South Korea in 1974. Its business developed around railway vehicles and the electrical technologies required to operate and modernize them. Rather than being limited to a single vehicle category, the company built capabilities across electric multiple units, diesel multiple units, automated peoplemovers, rubber-tyred metro vehicles, monorails, trams, and rail subsystems. In the South Korean market, Woojin became associated with equipment and vehicles used by major urban and national rail operators. Its references include electric multiple-unit series operated by Korail, Seoul Metro, and Busan Metro, as well as automated peoplemover systems at Incheon International Airport. It also participated in newer urban-transport projects, including the Sillim Line in Seoul and the battery-powered Wirye Line tram. For the Daegu Metro Class 3000 monorail, Woojin supplied components in cooperation with Hitachi Rail rather than acting as the sole vehicle supplier. The company's international work includes both complete transportation systems and targeted modernization projects. In Indonesia, it supplied vehicles for the Kualanamu Airport Rail Link and the Soekarno-Hatta Airport Skytrain. It refurbished 16 trainsets for Malaysia's KTM Class 83 fleet. In the Philippines, it provided new propulsion and monitoring systems for three Manila Light Rail Transit LRTA 2000-class trainsets. In Taiwan, it supplied static inverters for the modernization of 63 Taiwan Railway EMU500 trains as a subcontractor to Mitsubishi Electric. Woojin established a local corporation and production plant in Los Angeles in 2011. From that base it supplied broadcasting display devices, driver-cabin devices, and auxiliary power devices to transportation departments in Washington, Oregon, Massachusetts, and Utah. Its United States presence later supported a major fleet-modernization role when Los Angeles Metro selected the company in 2024 to refurbish the Breda A650 fleet. The project covers 74 cars, equivalent to 37 trainsets, and was linked to the transit system's preparation for the 2028 Summer Olympics. Woojin entered the electric-bus market in 2016. It introduced the Apollo plug-in electric low-floor bus family at the 2017 Daegu International Future Auto Expo. The Apollo range includes the 700, 900, 1100, and 1200 models, representing different vehicle size classes. Production was associated with the Ochang plant in Cheongju, North Chungcheong Province. A further expansion came with the completion of an electric-bus smart factory in Gimcheon in 2024. The facility was described as having annual capacity of 1,500 buses and began mass-producing electric buses in the second half of that year. Woojin planned additional investment in 2025 to support output above that level. This development broadened the company's role from rail manufacturing and systems engineering into large-scale zero-emission road-transit production.
