Example Train Images
This is a sample of a northbound train at night. This video was taken after the camera was moved. This enabled the camera to have a more direct view of the tracks - which makes the identification of a contour and subsequent tracking much more reliable. (I don't know why there is distortion and other oddities at the end of the clip.)
Train angling away from camera. This was taken with the camera in the old location.
Train angling toward camera. Again - this is shot from the camera's old location.
