All trains have been cancelled on several lines in the counties Östergötland and Södermanland.
Östergötland is experiencing problems finding busses to replace the cancelled trains, as all traffic in the area is affected by the disturbances.
The storm has also caused the flooding of an equipment shelter in Norrköping, in central Sweden.
A powerful storm wreaked havoc over southern Sweden on Friday night, coming in from the east. A total of 3,000 bolts of lightning were registered over Östergötland, as well as in a smaller area in Stockholm, according to meteorological institute SMHI.
“We’ve got a little depression moving west, which is causing a lot of thunder,” said Erica Thiderström, meteorologist at SMHI, to news agency TT.
