Siheung City Calls for Sincheon-Sillim Line, GTX-C Extension to Oido to Be Included in National Rail Network Plan

Siheung City seeks stronger links with Gwangmyeong and southwestern Seoul
Also calls for swift launch of Southwestern Metropolitan Railway private investment project

Gyeonggi Province's Siheung City has asked the Ministry of Land, Infrastructure and Transport to include the Sincheon-Sillim Line and the extension of the GTX-C line to Oido Station in the 5th National Rail Network Plan.

Siheung City officials visited the Ministry of Land, Infrastructure and Transport on the 5th to urge the inclusion of the Sincheon-Sillim Line and the GTX-C extension to Oido Station in the 5th National Railway Network Construction Plan. Provided by Siheung City.

Siheung City, led by Mayor Lim Byung-taek, said on November 9 that it had explained the need for the two projects to the Ministry of Land, Infrastructure and Transport on November 5 and requested their inclusion in the national plan. As the process to finalize the 5th National Rail Network Plan is underway, the city plans to focus on consultations with relevant organizations.

The Sincheon-Sillim Line is a proposed metropolitan railway connecting Sincheon Station in Siheung with Sillim Station in Gwanak-gu, Seoul, over approximately 16.4 kilometers. The line would connect Siheung, Gwangmyeong, and southwestern Seoul from east to west. The project aims to improve transportation conditions in Siheung, which is near Seoul but has limited access to rail services.

Siheung City signed a joint agreement with Gwangmyeong City, Geumcheon-gu, and Gwanak-gu in 2022 and has conducted reviews of the route and project feasibility, including a preliminary feasibility study. Based on the findings, the city has continued joint efforts and consultations with relevant organizations to secure the line's inclusion in the National Rail Network Plan.

After a proposal to pursue a private investment project for the Southwestern Metropolitan Railway was announced in December 2025, combining and restructuring the Second Gyeongin Line, the New Guro Line, and the Sincheon-Sillim Line, the city also called for the private investment project to be launched promptly.

The proposed extension of the GTX-C line to Oido Station would extend the route, currently planned to run as far as Sangnoksu Station, by approximately 14.2 kilometers to Oido Station in Siheung. Siheung City has pursued the project through its own preliminary feasibility review and consultations with Gyeonggi Province.

The proposed route was included in the "GTX Plus Basic Plan" prepared by Gyeonggi Province in 2024. The province has also asked the Ministry of Land, Infrastructure and Transport to include it in the 5th National Rail Network Plan.

Siheung City expects that future growth in transportation demand, driven by the development of national high-tech strategic industries and the redevelopment of aging planned cities, will help improve the economic feasibility and viability of the Oido Station extension project.

A Siheung City official said, "Railways are key infrastructure that not only make travel more convenient for citizens but also drive regional growth and balanced development. We will continue to work with the Ministry of Land, Infrastructure and Transport, Gyeonggi Province, and relevant local governments to ensure that both projects are included in the National Rail Network Plan."
