The rest of the film shows his imagined idea of what would happen, with children being split into four competitive teams to take part in different activities often carried out by young people trespassing on the railway.

Each time, the consequences of these activities are shown, such as one scene where a driver and passenger are left badly injured by broken glass after a child throws a brick through the train window.

The film finishes as a group of adults appear and go into the tunnel to carry out the bodies of the dead and injured children, which are then laid out in a long line along the railway track.

The camera pans out to show all the dead and bloodied children along the track before returning to the boy sitting on the railway bridge wall, who seems to be reconsidering the idea.

The "stone-throwing" competition was filmed immediately north of the railway bridge on the western side embankment where the AWS signal ramp is.
