Teen hacks tram system, derails trains

In yet another "innocent prank" that turned out to have very real-world effects, a 14-year-old Polish boy has admitted to modifying a TV remote in order to manipulate the junction-switching devices on the Lodz tram system, resulting in four derailed trains and 12 injuries. According to reports, the teenager snuck onto tracks to study the switching mechanisms, and used the resulting knowledge to re-direct trains "like any other schoolboy might a giant train set," as a police spokesman put it. The young man now faces charges in juvenile court for endangering public safety.
