Railway department of Seoyoung has achieved outstanding growth by participating in the entire railway project including private/turnkey/technical proposal for more than 20 years since it started to participate in the turn-key project for the dual-track Gyeongchun Railroad Line in 1999. Our company maintains the highest level of sales per person over the last 3 years. Railway department, a late entrant in the industry, succeeded in sighing the turn-key projects in a competitive design market through accumulated experiences by value engineering.
Not stopping at the achievements of the past, the railway department continually participates in the national R&D project including the infrastructural research for the improvement of the speed of the rapid transit railroad. PRT research services and improvement of the speed of the existing lines through the inputting of tilting railway trains enhance the technologies to lead the future national railroad projects. In addition, we have made contributions towards the building up of the national railroad network by executing several preliminary feasibility studies.
Railway department has been providing various services including feasibility study, basic plan, basic and execution designs for the railroad construction projects in Korea and overseas that encompasses rapid transit railroad, general railroad, metropolitan railroad, urban railroad and light rail transit, etc. Moreover, we are promoting the advanced railroad construction technology of Korea through the operation of railroad technology school in Paraguay in South
America and expanding it to other countries such as Mongolia, and putting in efforts in social participation through technology transfer to developing countries.
We participated in urban railroad construction projects including the Subway routes 7 and 9 in Seoul, Subway routes 1 and 2 in Incheon, Subway route 3 in Daegu, Hanam line, Gimpo city railroad and Jinjeop line, etc. Also in numerous arterial line railroad projects such as Jungang line, Gyeongchoon line, Janghang line and Gyengjeon line, etc. were planned and designed by Seoyoung.

◆ Key Projects

Dual-track railway for the Bujeon~Masan sector
Private sector investment facility project for the dual-tract railway for the Bujeon~Masan Sector
This project was aimed at activating the southeast region into the metropolitan economic zone by linking the Donghae Nambu Line, supporting railroad of the Busan New Harbor and Gyeongjeon Line and to increase the efficiency of the railroad transportation by providing transportation conveniences to the residents of Busan and western Gyeongnam region. With the design concepts of creation of the quick and convenient scenic image (Speed Line), formation of safe and pleasant scenery (Safety Line), railroad environment with ubiquitous and automated system (Smart Line) and formation of sustainable and environment-friendly scenery (Sustainable Line), the project pursued the construction of railroad in which the natural sensibility, regional sensibility, human sensibility and technological sensibility harmonized.
The execution plan was approved in April 2014 and construction is currently underway with the schedule for completion in 2020.
