Plans for a Line D were announced in 2021 by the previous government. However, the proposed route faced a lot of opposition, and has not been approved yet. The new government of Yoon Suk-yeol has pledged to build three new lines (Lines D, E and F), for which the routes have not been decided yet, but which would likely include plans for a longer Line D than the one announced by the previous government. Plans for a Line G and H that will expand to the northern and southwestern regions of Gyeonggi Province have also been announced.{{Cite web |last=뉴시스 |date=2024-04-01 |title=GTX 플러스 노선안 공개…포천~인천, 파주~위례신도시 연결 |url=https://www.newsis.com/view/NISX20240401_0002682163 |access-date=2024-06-29 |website=뉴시스 |language=ko}}

Critics argue that GTX project would increase the social and economic centripetal force towards Seoul leading to increased primacy and the collapse of other provincial cities.{{cite news|last=Donggyu|first=Seong|date=March 19, 2014|title='문제 투성이' GTX사업…우려 확산|language=Korean|trans-title=GTX project in "full of problems" - Lots of Concerns Appear|work=Newsway|location=Seoul|url=http://www.newsway.co.kr/news/view?tp=1&ud=2014031814355137317&md=20140319154644_AO|access-date=January 18, 2021}}
