Common sense really does seem to be disappearing... why, oh, why is it necessary to warn people to stay away from the edge of train platforms?
Any instinct of self-preservation would surely be triggered by the 1.5m drop onto tracks, or the electrified line or the sheer SIZE of trains passing at speeds in excess of 40km/h.... but no, I imagine that if something did happen, the train company would be sued.
Common sense for everyone, and transplants for those that have none!
