14-year-old "electronics genius" in Lódz, Poland, built
a remote control for the city's tram system (apparently out of a TV remote control, though presumably they mean that he housed it in a TV remote control case ) and used it to change points, forcing trams onto the wrong tracks, until he was arrested.
"He had converted the television control into a device capable of controlling all the junctions on the line and wrote in the pages of a school exercise book where the best junctions were to move trams around and what signals to change.
Problems with the signalling system on Lodz's tram network became apparent on Tuesday when a driver attempting to steer his vehicle to the right was involuntarily taken to the left. As a result the rear wagon of the train jumped the rails and collided with another passing tram. Transport staff immediately suspected outside interference.
