At around 2:23 a.m. on January 15, 2013, a commuter train sitting at the Neglinge depot outside Stockholm, Sweden, suddenly began to move. It accelerated toward the terminus at Saltsjöbaden, roughly 1.7 kilometers (1.1 miles) away.
The train consisted of two C10/C11 two-car units, four cars in total. In the Swedish Accident Investigation Authority’s accident analysis, the train was treated as weighing roughly 90 metric tons. It reached around 80 km/h (50 mph) before crashing through the buffer stop and continuing toward a residential building about 30 meters (100 feet) beyond the end of the track.
There was only one person aboard: a woman who had been cleaning the train. She was seriously injured. No one in the building was reported injured.
Within hours, however, the accident acquired a much more sensational explanation. Reports around the world said that a cleaner had stolen an empty train, driven it at high speed and crashed it into a house.
Three days later, that story began to collapse.
