The Italian news agency ANSA cited unnamed police sources who quoted the 14-year-olds saying they sabotaged the tracks because they were bored and did it "for kicks. We wanted to see how a train comes off the rails, what the impact would be like."
Police said the pair, who came from well-off families, had tried their stunt three previous times in February but were foiled each time by engineers who saw the concrete blocks in time, ANSA reported. In January, five boys were caught after they put concrete blocks, copper cables and wooden beams on train tracks near Milan.
