Separate operating, construction, pre-construction, and planning-stage GTX lines using the current official project-status snapshot.
The Unjeong Jungang–Seoul Station and Suseo–Dongtan sections are operating separately, with the central Samsung Station connection still outstanding.
The 2026 non-stop passage and 2028 full-opening dates are government-plan targets. Seoul's 2026-09-23 statement on Samsung Station reinforcement is a city position statement, not a final MOLIT schedule decision.
The 2026 government work plan classifies GTX-B as a project that began construction in August 2025 and presents a 2031 opening target.
Private-investment and publicly funded sections can progress on different schedules, so one project-wide construction percentage should not be assumed.
An amended implementation agreement cleared the private-investment review in August 2026; construction is to follow construction-contract, financing, and commencement procedures.
The official 2026-08-25 material describes a construction target, not confirmation that full construction had already begun.
Under the 2026 work plan, additional GTX lines remain under review for inclusion in the 5th National Railway Network Plan.
Route alignments, stations, station names, and timing shown in earlier concept maps are not final and can change.
