Uijeongbu City, which was the first to request the extension of Line 7 (about 20 years ago), has been strongly advocating for the double-tracking of the Dobongsan-Okjeong Line since 2023.
However, is it possible to construct a double-track line while construction on even single-track subway lines is being delayed?

For reference, the Line 7 train featured in the thumbnail is from the Seoknam Extension, which opened in 2021. It was manufactured by 'Dawon Systems' and shipped from the factory in 2019. It is not directly related to the Dobongsan-Pocheon Line.
