Occasionally a reader will tell the following story, usually attributing it to a local site. Once, there was a tragic accident on a set of traintracks:
A busload of children was crossing the tracks, and could not get out of the way in time to avoid the approaching train. Now, if your car stalls out on the tracks, it will be pushed over the tracks to safety before the train hits you. The ghosts of the children have saved you, and sometimes you can see their small handprints in the dust on your car.
The most well-known example of this urban legend are the haunted traintracks in San Antonio, Texas, but it occurs elsewhere as well.
For an explanation of how things can appear to move "uphill", see FAQ 5.7.
