Two on-site inspections of [Woojin Industrial Systems](https://akta.pro/company-profiles/000chrv/woojin-industrial-systems) by the Fair Trade Commission have found no apparent evidence of bid-rigging, according to an industry source familiar with the matter, [Naver](https://n.news.naver.com/mnews/article/044/0000291627) reported on November 2. The regulator opened the investigation on October 21 into Woojin, Korea's second-largest railway vehicle manufacturer, and at least one other parts supplier over suspected collusion in railway parts procurement tenders.

## What the Fair Trade Commission Inspections Found

The source, who asked not to be identified, said neither of the two inspections at Woojin had turned up evidence of wrongdoing. "Neither of the two inspections at Woojin thus far has turned up evidence of wrongdoing," the source said. The Fair Trade Commission has not announced any findings or indicated when its investigation might conclude, and the regulator declined to comment on the ongoing investigation.

The inquiry centers on a business that has become a relatively small part of Woojin's operations. Founded as a railway parts manufacturer in 1974, Woojin entered the rolling stock market in the 2010s and expanded into higher-value vehicle contracts. Domestic parts sales now account for about 5 percent of its total revenue, or less than 10 percent including overseas sales. "Since Woojin has moved almost entirely to finished vehicles, parts tenders hardly matter to it," the source said.

The source argued that Woojin's limited exposure to parts tenders and established manufacturing capabilities give it little incentive to engage in collusion. "Collusion is something companies do when they struggle to win bids on their own or want to inflate prices," the source said. "Woojin has no reason to do either." Woojin now participates mainly in parts tenders involving maintenance or upgrades of trains it previously manufactured, and in some cases its proprietary technology makes it the only qualified supplier, according to the source.

## Woojin Industrial Systems' Contract and Factory Records

According to akta.pro [company records](https://akta.pro/company-data), Woojin won an approximately 300 billion KRW (about $200 million) LA Metro A650 heavy rail vehicle refurbishment contract in 2024 covering up to 74 subway cars ahead of the 2028 Olympics, and is establishing a Carson, California factory to execute it. The same records show the company completed construction of the Gimcheon factory in Gyeongsangbuk-do and the Godeok Office in Seoul's Gangdong-gu in 2024. Woojin was founded in 1974 and is headquartered in Seoul, with an estimated revenue of $250 million to $500 million, according to its profile.

## Earlier Woojin Industrial Systems Milestones

In October 2026, Woojin Industrial Systems was selected for the Ministry of Employment and Labor's annual recognition program for job creation and improved working conditions, Koreatimes reported. In May 2026, the Korean rolling stock manufacturer began test operations on the first overhauled two-car unit from LA Metro's A650 fleet at its Osong test track in South Korea, according to The Korea Herald.

## What Comes Next for the Fair Trade Commission Case
