Swedish police search for answers in theft and crash of commuter train STOCKHOLM, Sweden, Jan. 16 (UPI) -- Swedish police said they hope to question the woman who stole a commuter train and rammed it into an apartment building. The woman, identified as a cleaner in her early 20s, Tuesday took the train from its depot on the Saltsjobaden commuter line that links Stockholm to its upscale suburb. The train broke through the end-stop barrier and careened into the building. No one in the building was injured. It's priority No. 1 for our investigators to interview this person," police spokesman Lars Bystrom told the TT news agency Wednesday. The woman was taken to a hospital where doctors said she sustained serious but not life-threatening injuries. A motive for taking the train was not known, TT said. Police said they also want to talk to about how she took the train. Police official Anders Lindstrom said during a news conference a key was in the train and "the brakes weren't on." To get a train moving, the driver must override a safety feature. Police also are looking into how to safely remove the wreckage that remained in the two-floor apartment building.
