Transit officials in Sweden are at a loss to explain how a cleaning lady was able to steal a commuter train from a station near Stockholm and drive it for three minutes before crashing into a three-story house.
Luckily, no one was on the train at the time of the accident, which occurred early Tuesday morning.
A spokesman for Stockholm County's transit operator Storstockholms Lokaltrafik said the twentysomething woman seized the train around 3 AM and drove it for two stops before derailing in the Stockholm suburb of Saltsjöbaden.
The train slammed into the first-floor kitchen of an apartment building where three families live. The cleaning lady had to be rushed to the hospital with "serious" injuries, but none of the building's residents were hurt.
An investigation into the incident has been launched, with local politicians demanding to know how an unauthorized person was able to commandeer a commuter train.
A spokesman for Arriva, the subcontractor that operates the line, said driving their trains wasn't that complicated.
"Generally speaking that's possible even if you're not a train driver," he told the Associated Press. "You can read about it on the Internet, or observe how others do it."
