The X2000 high-speed train, which was travelling between Stockholm and Gothenburg, encountered problems just north of Gnesta station, near Södertälje, at 9:25am on Thursday. One of the train's axles left the tracks, and the driver was forced to brake sharply. Nobody was injured in the accident.
Passengers from the train were evacuated to Gnesta station, where they were transferred to alternative transport. The incident was on Thursday morning causing delays to other services, but a spokeswoman for rail infrastructure authority Banverket said it had been possible to divert trains around the scene of the accident.
The cause of the accident is so far unclear.
