The timber truck has, for unknown reasons, driven off Häggvägen, which runs between Vallvik and the former E4.
The accident occurred at 6 pm on Friday.
- The crane on the timber truck has crossed the railway and when it has moved, it has also torn down a power line and injured two others, says Christer Fagerhov, operations manager at the rescue service in southern Hälsingland.
The railway in question is an industrial track where traffic has now been stopped.
The demolished power lines cause power outages in Vallvik.
- The electricity companies are on their way out and will fix the whole thing, says Christer Fagerhov to SVT at 19 o'clock.
No person was injured in the accident. A lane is closed but it is possible to pass the accident site.
