This Guy Is A Genius

And a serious menace to Polish society:

Adam Dabrowski, 14, described by teachers as a model pupil and an electronics genius, hacked into the public transport network in Lodz to change the track points derailing at least four trams and leaving dozens injured.

...He told police in Lodz in central Poland he had changed the points on tram tracks across the city for a prank. But in one incident alone 12 people were injured.

The giant train set started operating at 1pm on Tuesday when a city tram driver tried to steer his vehicle on to right hand tracks, and found himself helpless to prevent it swerving to the left instead, seemingly of its own accord.

The rear wagon then swung off the rails and crashed into another passing tram, hurling screaming passengers to the floor.

Transport employees said they knew immediately that someone outside their staff had caused the accident.

Miroslaw Micor, spokesman for Lodz police, said: "He studied the trams and the tracks for a long time and then built a device that looked like a TV remote control and used it to manoeuvre the trams and the tracks."

Mr Micor added: "He had converted the TV control into a device capable of controlling all the junctions on the line and wrote in the pages of a school exercise book the best junctions to move trams around and what signals to change.

..."Four trams were derailed, and others had to make emergency stops that left passengers hurt. He clearly did not think about the consequences of his actions."
