When the rescue service arrived at the scene, they found embers along the rails.
- It is above all a sleeper on the rails that has burned up, says Pedher Helmer, internal commander at the Rescue Service Östra Götaland.
Train traffic is completely stopped during work.
According to Helmer, the fire has been extinguished and the rescue service has been completed on the spot.
What awaits, before the railway opens up for traffic again, is that the Swedish Transport Administration will examine the line.
- They need to get someone out to check if everything is okay, he says.
The traffic stop affects the trains that run between Norrköping and Stockholm.
How long there will be a stop in train traffic is currently unclear.
