The Ministry of Land, Infrastructure and Transport says it has passed the preliminary feasibility study on the GTX B line.

The GTX Line B is a total of 80.1km from Songdo, Incheon, connecting Namyangju Maseok.

The train runs at a maximum speed of 180km per hour, and it takes 27 minutes from Songdo to Seoul Station.

If the follow-up procedures, such as the establishment of a basic plan, proceed without disruption, construction is expected to begin in late 2022.
