"SL currently sees a high risk of continued disruption to metro traffic on Monday morning," said Storstockholms Lokaltrafik (SL) in a press release.
The Red Line has a fault in its signaling system, causing delays and complete shutdowns. Experts have even been flown in from Germany to repair it.
At the same time, sun-induced rail buckling and a switch failure have affected the Green Line.
In both cases, there is no forecast for when traffic can return to normal.
"SL therefore urges travelers to allow extra time, follow the latest traffic information and, if possible, consider alternative routes for Monday morning."
