Fully understand your thoughts on the matter and recollection/flashbacks, people who trespass have no idea of the trauma that can be caused!!! I will never forget an incident we attended at Northallerton several years ago, report of a loss of red aspect for the Bi-Di signal on platform 2. We attended as fault team on duty for a routine failure, what we found was anything but. TPWS modules showed an OSS (over speed sensor) fault causing the loss of red aspect, as we approached the on track equipment from the far end of the station we came across a horrendous scene of a suicide- a woman had leapt in front of a north bound coal train and damage to the TPWS grids on track had occurred. BT police were on scene and we unwillingly observed scenes that will never leave me. Some of these folk who wander onto the track should be aware of what can happen and that there's no second chance.
