Switzerland train crash: Passengers injured after collision north of Zurich

Rescue workers inspect the site of a train crash at the train station of Rafz, northern Switzerland, on February 20, 2015. (AFP)Two trains slammed into each other near the Swiss city of Zurich, tipping over carriages and injuring at least five people, one seriously, police said.

The accident happened when a regional intercity train hit a commuter train at the Rafz train station, around 30 kilometres north of Zurich and not far from the German border, police and media said.

The locomotive on one of the trains was smashed in, with broken glass and twisted metal visible through a gaping hole in the side, abc.net.au reports.

The train derailed, and several of its carriages tipped on the side.

Ambulances, fire and rescue services were sent to the scene, while a rescue helicopter hovered above the crash site.

"There was an accident this morning, it's serious, there are injured," a police spokeswoman told AFP.

Police in Zurich said in a statement at least five people were injured and one of them was in serious condition.

An 18-year-old passenger on the commuter train told the paper that it had just begun pulling out of the Rafz station on its way to Schaffhouse when the conductor hit the breaks.

"An express train from Zurich came up from behind and hit the side of our train, the intercity train derailed," said the man, whose name was not given.

Both the trains had been "quite damaged", he said, adding that the conductors on both trains had quickly evacuated the passengers.

Lars Fehr told local media he had been sitting in the Rafz station waiting room when the crash occurred.

"Suddenly there was a loud bang," he said, adding that both the trains had been heading in the same direction.

Mr Fehr said a woman had called the police and some people had headed out to the derailed train to help.

"The conductor got out of the locomotive, put on a safety vest and helped passengers out of the train," he said.

The Swiss are Europe's top rail users, and their network is normally envied abroad for safety and quality.
