Business Areas

• Railway Track Construction: This business involves constructing structures on which trains run, combining rails, sleepers, fastening devices, etc., which directly affect the safe operation of trains and comfortable ride quality. The company has experience in constructing various track systems, including high-speed railways, conventional railways, and light rail.
• Manufacturing and Sales of Railway Track Products: The company produces and supplies core components for railway tracks, such as turnouts that determine train routes, sleepers that support the track, rail expansion joints, and electrical signal products. It successfully developed and localized high-speed railway turnouts for the first time in Korea.
• Railway Maintenance: Through rail grinding and facility maintenance projects, the company maintains railway facilities in optimal condition. It actively participates in maintenance projects to meet the high safety standards required by changes in the train operating environment.

Products

• Turnout: A device that switches the path of a train running on a track to another track, it is a comprehensive structure of the most important track and signal sectors on the railway. Sampyo Railway was the first in Korea to localize high-speed turnouts for concrete tracks and applied them to the Honam High-Speed Railway project.
• PSTS (Precast Slab Track System): This is a concrete track construction method where precast concrete slab panel structures are manufactured in a factory, transported to the site, and assembled. Compared to cast-in-place tracks, it offers advantages such as ensuring uniform high quality, shortening construction time, and improving the working environment.
• Rail Grinding: This is a maintenance technology that precisely grinds and polishes the rough surface of the railhead to continuously maintain the quality of the rails that make up the track. By introducing 30-seat and 24-seat large rail grinding vehicles, it contributes to enhancing the comfort and safety of train operations.

Special Notes

• Korea's Only Comprehensive Railway Engineering Company: It is the only comprehensive railway engineering company in Korea that covers all areas of the railway track sector, from manufacturing railway track products to construction and maintenance. This allows it to occupy a unique position within the railway industry.
• World-Class Technology and Successful Localization: The company has secured world-class technology, including establishing the first turnout production plant in Korea and successfully localizing high-speed turnouts for high-speed railway concrete tracks. It continuously conducts research and development through its Railway Technology Research Institute.
• Overseas Market Expansion and Competitiveness: The company is actively expanding into overseas markets such as Taiwan, the Philippines, and India, where its technology and quality are recognized. In the Taiwanese railway market, in particular, it surpassed Japanese companies to achieve the top market share in railway turnouts.
• No. 1 in Railway Track Construction Capability Assessment: The company secured the top position in the 2025 railway track construction capability assessment, proving its highest level of technology and construction capabilities in Korea. This is an important indicator for understanding the company's market position.

Recruitment Information

• Main Hiring Positions: The company primarily recruits for railway-related engineering and technical positions, such as railway track product development and localization, railway track construction and installation, rail grinding, and facility maintenance.
