Woori Technology is
Leading the new future of railway control systems
PSD Business
We are developing, designing, producing, testing and tria-running railway systems.
In particular, we have developed SIL4, the highest level of safety integrity level, for railway platform security (PSD) and railway signal control system (CBTC) for the first time in Korea.
And now SIL products are available.

With this SIL product, we are striving to expand market share not only in domestic market but also overseas market. n addition, by developing vertical PSD (Vertical PSD) that can cope with multi-car service sections that can not be applied to conventional horizontal PSD, we have ensured the safety of our products on the rail platforms of domestic and overseas trains.
In particular, this product is being piloted at SNCF Bangs-Malakoff station in France, and at Can Cuias operated by Spanish railway operator TMB in Barcelona.
With the SIL4 certification of various railway control systems, we provide a wide range of services such as railway system installation, maintenance, and repair on the basis of the unique technology for safety control at home and abroad.
