A bunch of good ideas there! Anyhow, as to "Railway Children", the phenomena usually occurs at level crossings, and the story usually involves a school bus or similar vehicle full of children which stalls on the tracks, and is hit by an oncoming train. Thereafter, if you stop your car on the tracks and leave it in neutral, the ghosts of the children are said to push it off of the tracks to avoid a repeat of the accident that claimed their lives. I've checked out a few of these cases and they are usually just an urban legend, but in one case that I was personally involved in investigating, my car WAS pushed off of the tracks(and the ground was perfectly level at the crossing, I checked), not only that, but there were small handprints left in the talcum powder that I had covered the bumper and trunk lid with. Also, my EMF meter went right off the top of the scale.
