What's being done to stop rail crime?
We all know railways can be dangerous places, but that's not stopping young people committing thousands of crimes on or around the tracks every year.
Latest figures show young people commit 100 crimes a week on the railways and it's even worse during August.
For some, throwing things at trains or dodging them at high speeds is their idea of fun, but they're breaking the law and putting their lives in danger.
Last week, a 13-year-old boy died when he was electrocuted near a railway.
Liam had apparently climbed onto a disused train in Liverpool when he was electrocuted by the overhead power lines. Two mates he was with were also hurt.
While police investigate Liam's death, more is being done to encourage kids to stay away from railways and disused tracks.
Launched earlier this year, with the backing of boxer Amir Khan, the No Messin' campaign encourages kids not to hang around railways by getting them involved in music and sport.
The people who look after train tracks in the UK, Network Rail, say trespassing and crime on the railways is going down, but they want to get it as low as possible.
Gemma Duffy from Network Rail warned that electricity at railways is stored in two places - the tracks and overhead wires.
"The electricity that runs through overhead wires is 25,000volts," she said. "That's about 100 times more powerful than electricity at home, and you wouldn't put your fingers in a plug socket."
