The blue line's station is being built beneath Hammarby kanal and will be, in Region Stockholm's words, the first underwater station in Stockholm. The platform lies 40 metres below ground and the station gets two exits: one at Vintertullen on Södermalm, entered from the ground floor of Katarina Bangata 80, and one in Luma next to the tvärbana light-rail stop at Lumaparken.

No new timetable has been decided yet.
