Since first participating in the Gyeongchun Line Double-Track Electrification Project under a turnkey contract in 1999, Seoyoung Engineering’s Railway Division has undertaken a wide range of railway projects for over 25 years, including private investment, turnkey, and technical proposal projects. With technical expertise developed through Value Engineering (VE) and extensive design experience, the division has established a competitive position in the railway construction sector.
The Railway Division has strengthened its technical capabilities through participation in national R&D projects focused on increasing operating speeds on high-speed railways, Personal Rapid Transit (PRT), and tilting train technology. It has also contributed to the expansion of national and regional railway networks through railway network planning, preliminary feasibility studies, and pre-feasibility studies.
The Railway Division provides comprehensive engineering services, from feasibility studies to basic and detailed design, for domestic and international projects covering high-speed rail, conventional rail, metropolitan rail, urban rail, and light rail transit. Recent major projects include the Goyang–Eunpyeong Metropolitan Railway, the Okjeong–Pocheon Metropolitan Railway, the Gangneung–Jejin Single-Track Electrified Railway Construction Project, the Pyeongtaek–Osong Quadruple-Track Railway Construction Project, and the Second Urban Railway Network Plan for Busan Metropolitan City.
In the urban railway sector, the division has participated in projects involving Seoul Subway Lines 7 and 9, Incheon Subway Lines 1 and 2, Gwangju Metro Line 2, and the Gimpo Urban Railway. Its metropolitan railway projects include GTX-A, the Goyang–Eunpyeong Metropolitan Railway, the Okjeong–Pocheon Metropolitan Railway, the Hanam Line, and the Jinjeop Line. The division also continues to expand its business scope through participation in mainline railway projects, including the Jungang, Gyeongchun, and Janghang Lines, as well as railway projects in Paraguay, Mongolia, and Egypt.

◆ Key Projects
- Preliminary and detailed design sevice(T/K) for Sector 4 of the dual-track subway of Hanam Line (Sangil~Geomdansan)
This project is to connect the existing the Seoul Subway Line 5 by building the new subway line to meet the demands of new housing development districts and to build the wide transport infra structure in eco-friendly Hanam city.
This project with a total length of 1.303km is composed of 1 subway station, 2 main ventilator and a tunnel (1.1km).
The project includes the subway station that should be a symbolic location due to its proximity to the Hanam City hall.
Especially, the project should minimize operating and construction costs in that the project is expected to endure operational deficit.
To improve the narrow sidewalk conditions of the old city, we completed ground expansion design works successfully through the comprehensive review of the development plans and road conditions changes.
The subway station is planned to be constructed as the longest span(22m) no pillar underground structural systems for the very first time in Korea. The duplex shops around the square with open space as a large circular square of height 7.2m for increased profitability
And, the linear design for the vertical alignment using the concept of Positive Hump is implemented to minimize subway station depth and improve the accessibility of the passengers as well as minimizing the construction and operating costs through the annual 30,000kWh saving of operating energy reduction.
This construction started work by completing detailed design in July 2015 and the subway line is expected to be opened in 2020.
