Fifteen people were injured, including at least one seriously hurt, in two separate train derailments that happened in quick succession Friday in stormy wind in northwestern Switzerland, police said.

The incidents, on regional passenger rail lines, took place about 30 kilometers apart, north of the Swiss capital Bern.

Three people were injured in the first, including the driver, and 12 were injured in the second, with wind speeds of 136 kilometers per hour recorded nearby.

The first incident happened at the lakeside village of Luscherz at around 4:30 pm, police said. The train had 16 people on board.

"While a strong wind was blowing... the front carriage of the train overturned on the right of the track, slipped down a small embankment for a few metres and finally came to a halt," Bern cantonal police said in a statement.

"Three people, including the driver in the overturned carriage, were injured, treated by four ambulance teams and taken to hospital."

The front carriage of the two-carriage train could be seen lying on its right side off the single-line track, on the grass verge between a path that runs alongside the railway line and a ploughed field.

Workers in orange workwear and hard hats were at the scene, with a ladder placed alongside the carriage so they could reach the upturned left side. Firefighters helped to get people out.

The rear carriage rolled on for a few metres before coming to a stop.

A power mast was damaged, putting the line out of action.

"An investigation has been opened to determine the circumstances and causes of the accident," police said.
