The British Transport Police (BTP) will be targeting railway trespassers in the next few weeks as the school summer holidays get underway.
More than half of all railway trespassers are aged between 14 and 25.
The lighter evenings usually show an increase in trespass cases, some of which include vandalism.
Between April and June this year BTP recorded almost 2,400 trespass incidents, of which almost 1,300 involved people aged 25 or younger.
Under the banner of Operation Intruder, BTP officers will target trespassers at problematic locations.
This will include increased patrols in a bid to try to ward off would-be trespassers who either think the track is a place to hang out or commit vandalism.
BTP is enlisting the help of other police forces and the rail industry, including the use of helicopters, to report trespassers. Officers will also report any damage to railway property so it can be repaired and helpto stop people gaining access to the track.
Chief Inspector Tom Naughton said: “Children and young adults need to understand the dangers of the railway – that’s the message. “While taking trespassers through the courts remains open to BTP, the main focus of this campaign is prevention – stopping people getting on the track in the first place.
“Our officers have already visited a number of schools to warn children, face-to-face, of the dangers of straying onto the railway. We need parents to play their part, too – making children aware of the dangers.”
