Youngsters have been warned to stay away from railway lines.
The lighter evenings and school holidays have prompted the British Transport Police (BTP) to remind parents and young people about the dangers of playing on or near railways.
The police and Network Rail have traditionally found an increase in the amount of crime being reported at this time of year.
These include trespass, stone throwing, vandalism and obstructions being placed on the tracks.
Temporary chief superintendent for BTP John McBride said: “I am urging youngsters to stay away from the lines and asking all parents to emphasise the dangers.
"If you live near a railway line, please ask yourself if you know where your children are playing.”
There is 25,000 volts of electricity passing through the overhead power lines and trespassers do not even need to touch the cables to get a shock as electricity can jump.
Contact BTP on 0800 405040 to report a crime.
