SEOYOUNG ENGINEERING

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

Trackbed alternative designs for sections 1 and 2 of the Honam high speed railway (HSR) 1-2

Honam Rapid Transit Railroad is a part of the KTX in Korea and extends from Yongsan Station in Seoul to Songjeong Station in Gwangju. After having completed the basic plan for the project in August, 2006, design was executed over 3 years prior to the commencement of the construction in May 2009. The operation of this railroad began on April 2, 2015. Honam Rapid Transit Railroad (Honam KTX) was constructed for the purpose of balanced growth of the country, particularly, the activation of economy in the regions of Chungcheong and Honam. It is a mega-scale national policy project with the total length of 182.3km and total budget of 8.33 trillion Won to link the Osong Station with Gongju Station, Iksan Station, Jeongeup Station and Songjeong Station in Gwangju.

Seoyoung Engineering was in charge of the execution design of the Sectors 1 & 2 (alternative design) and the Sector 4 among the Seoul~Songjeong, Gwangju Line. We executed the design under the slogan of “Towards the most outstanding railway, the Honam Line, that will run with the hope for the future by carrying the beautiful scenery of the regions including undulating hills, peaceful fields and clean rivers” by considering the geological conditions of the land on which Honam KTX is being constructed.

With the commencement of the Honam KTX, the traveling time between Yongsan, Seoul ~ Songjeong, Gwangju was shortened from 2 hours and 39 minutes to 1 hour and 33 minutes (average of 1 hour and 47 minutes). As a result, half a day life zone that was previously limited to the regions around the Gyeongbu Axis was expanded to the entire country.
