Guess this proves that tracks aren't really necessary then,
20-year-old cleaner stole train and crashed it into apartment in Stockholm
"I swear, officer - I tried to swerve and miss the appartments, but dumba***** made this train without a stearing wheel!"
This was an accident....during serving the trains at night the breaks were deactivated. Probably she happened to touch the throttle when she were cleaning the area around the drivers seat...and she was new on the job, she probably went panic scared and acted irrational, she seemed to have pulled the emergency brakes in different places, but the brakes were inactivated. It is really tragic.
