Osan City: "Join Forces to Extend the Bundang Line and GTX-C"... Urges Participation in National Railway Network Survey

Osan City Pushes to Include Bundang Line and GTX-C Extensions in National Rail Plan
Emphasizes "Transportation First, Occupancy Later" Ahead of 33,000 Homes in Segyo 3 District
Ministry Survey Closes at 3 p.m. on the 13th; City Urges Residents to Participate

Osan City in Gyeonggi Province has urged residents to participate in a Ministry of Land, Infrastructure and Transport survey to have the Bundang Line and the Osan extension of the GTX-C line included in the 5th National Railway Network Construction Plan. The city says the region’s rail network needs to be expanded in advance, as about 33,000 households are expected to move into Segyo 3 District following the occupancy of Segyo 2 District.

Osan Mayor Jo Yongho said, "The Bundang Line and the GTX-C extension to Osan are key rail projects that will ease residents’ commuting difficulties and support Osan’s future growth." He added, "Expanding the national railway network and providing government funding are necessary to meet rising demand for regional transportation resulting from development in Segyo 2 and 3 districts."

The Bundang Line extension to Osan would connect Giheung Station to Osandae Station via Dongtan. Osan City is also pursuing a plan to extend the line to Segyo 2 and 3 districts. Segyo 3 District is scheduled for completion in 2034 and will have about 33,000 households and a population of 75,900. A total of 15,629 residents participated in a signature campaign last April calling for the Bundang Line extension to Osan to be expedited.

The GTX-C extension to Osan is currently being pursued under a cost-bearing arrangement in which the party responsible for the project covers the costs. To ease the financial burden on local governments, the city plans to seek inclusion of the project in the National Railway Network Construction Plan and discuss central government funding with relevant agencies.

In August 2026, Mayor Jo met with Assemblyman Jeon Yong-gi, a member of the National Assembly’s Land, Infrastructure and Transport Committee, and sought his cooperation on extending the Bundang Line to Segyo 2 and 3 districts and drawing up measures to improve regional transportation in Segyo 3 District. That same month, he asked Hong Ji-seon, then Second Vice Minister of Land, Infrastructure and Transport, to select the Bundang Line extension for a preliminary feasibility study and include the GTX-C extension to Osan in the national plan.

The 5th National Railway Network Construction Plan is a statutory plan outlining the direction and investment plans for developing the national railway network from 2026 to 2035. The Ministry of Land, Infrastructure and Transport is conducting a preliminary survey until 3 p.m. on November 13, 2026. Residents can submit their views on inconveniences when using rail services and on expanding routes through the ministry’s website, the Korail+ app, or QR codes displayed at major railway stations.
