Train smashes into home in Sweden after cleaning lady allegedly stole it for joy ride

Stockholm A cleaner stole an empty commuter train from a depot Tuesday and drove it to a suburb of Stockholm where it derailed and slammed into an apartment building, officials said.

The woman was seriously injured in the early-morning crash and was flown to a Stockholm hospital, police spokesman Lars Bystrom said. No one else was injured.

Stolen train crashes into homes in Sweden

Bystrom said the woman was arrested on suspicion of endangering the public.

Tomas Hedenius, a spokesman for train operator Arriva, said the woman, born in 1990, stole the four-car train at a depot outside Stockholm.

She then drove it about a mile to the end station on the railway line, where it jumped off the tracks, careered for about 30 yards and crashed into a three-story building.

Photographs from the scene showed the crumpled front car of the train buried deep into the structure.

"There were three families inside the apartment building, but no one was injured. At least not physically," Hedenius said.

The motives of the woman, who worked for a company contracted to carry out cleaning for the train operator, were not immediately clear.

"We have only heard good things about her. We're investigating how this could happen, and why she did what she did," Hedenius said.

He said it's unclear how she got the keys to the train, but added that driving it is not that complicated.

"Generally speaking that's possible even if you're not a train driver," he said. "You can read about it on the Internet, or observe how others do it."
