This lady taught photography class at St. Francis Catholic School right across the street from the tracks. It is a steep climb up the RR embankment (part of the Sacramento Flood Control Levee System) to the tracks at this location, so she was not idly wandering around taking pictures. She was hit by a train on one track while filming one on the other. This stretch of rail is not high speed, and horns are often used to alert homeless people wandering on the tracks. There are no answers yet why she was trespassing and why she failed to avoid being hit.
