Warning: some viewers may find this video upsetting.

Think it’s fun to play on the railway or OK to take a shortcut along the tracks? Think again.This shocking real-life footage is a reality check.

In the last 10 years, almost 170 people have lost their lives trespassing on the railway. Almost half of those killed were under-25.

Most trespassers say taking a shortcut was their main motivation, followed by thrill-seeking. But walking along or messing around on the tracks can result in serious life-changing injuries or death.

We’re doing all we can to keep people safe by patrolling areas we know where trespass is likely to happen and stopping people from getting on to the railway.

We’re also working closely with Network Rail and train operators to reduce trespass by improving security across the network, using covert surveillance to catch offenders and going into schools to warn children of the dangers of trespassing.

But we can’t tackle this issue alone. We’re urging parents and young people to take a reality check when it comes to trespass. It’s not a game: they are real tracks, with real trains and real life-changing consequences.

If you’re a parent or carer, help us by talking to your kids about the dangers of going on the tracks.
