In recent days, a signal fault on the red line has caused disruptions in the subway.
Experts have been flown in from Germany, and as of Monday morning, the fault has still not been fixed.
"We are working on it around the clock. There was an ambition that it would be resolved by morning, but that didn't work," says Andreas Strömberg.
Cancelled departures are also expected on the green line following a previous switch failure, which has now been fixed.
We hope to be back sooner.
According to Andreas Strömberg, it is important that travelers stay updated on the latest traffic information.
"It's important to look at signs and listen to announcements," he says.
