Train traffic between Stockholm and Gothenburg came to a standstill on Saturday morning due to a power failure between Kallhäll and Enköping.
The sections affected were Stockholm C-Västerås-Hallsberg/Gothenburg.
There were also delays in train traffic between Malmö and Gothenburg due to a switch failure between Halmstad and Laholm.
Shortly after ten o'clock, traffic was underway again.
