A police operation is underway to try and minimise disruption on the rail network targeting the biggest causes, including trespass. As part of the campaign Network Rail has released video of young boys running across rail tracks in north London.
The video shows a group of youngsters at Mill Hill station in north London running from a train onto a platform and then across two railway lines onto another platform. One youth drops his bag on the track and returns to retrieve it. The group was never caught.
