On September 14, Yangju City Mayor Jeong Deok-Young announced that he welcomed the groundbreaking of the GTX-C line and stated that the city will actively cooperate with relevant agencies to ensure the project is completed on schedule without any setbacks.


According to the Ministry of Land, Infrastructure and Transport, the GTX-C line is a metropolitan express railway with a total length of 86.6 kilometers, starting at Deokjeong Station in Yangju and passing through key Seoul districts such as Uijeongbu, Chang-dong, Cheongnyangni, and Samseong, then extending to Suwon and Sangnoksu.


The start of construction had been delayed due to negotiations on increasing project costs following financial agreements and rising materials expenses. However, after an arbitration award by the Korean Commercial Arbitration Board in April and approval from the Private Investment Project Deliberation Committee in August, the main construction is now able to commence.


When the GTX-C line opens, the current travel time of more than 80 minutes between Deokjeong Station and Samseong Station will be shortened to approximately 30 minutes. Improved accessibility to the Gangnam area of Seoul is expected to help Yangju City develop both as a major transportation hub for northern Gyeonggi Province and as a self-sustaining city.


Mayor Jeong Deok-Young stated, "Together with the 300,000 citizens of Yangju, I welcome the commencement of full-scale construction for the GTX-C line," adding, "We will continue close cooperation with all relevant agencies during the construction process to ensure the timely completion of the project without any further delays."



Meanwhile, the GTX-C line is being pursued as a Build-Transfer-Operate (BTO) private investment project. The construction period is expected to last approximately 60 months from groundbreaking, with the line scheduled to open in 2031.
