The patience of Stockholm-area commuters was tested Monday morning as trains in both directions were both delayed and cancelled.
“It’s not a complete stop, but they’re working on the one set of tracks and that means that traffic can go no faster than 30 kilometres an hour,” Peter Behrmann of the Swedish Transport Administration (Trafikverket) told the Aftonbladet newspaper.
He added that the agency cannot predict how long the delays will last.
Experts have spent the morning inspecting the tracks and determining whether they can be used or need to be repaired.
The problem stems from a train with a damaged wheel that was driven on the tracks on Sunday night.
Södertälje and Gävle, both in eastern Sweden, are connected by a rail line that runs for roughly 200 kilometres.
The line includes the Uppsala-Stockholm stretch that is popular for commuters in Uppsala who work in the capital.
