The setting is in Duran, New Mexico on a July summer night in the year 1960, going on 2:06 am. Still yet off in a distance, is the Southern Pacific passenger train that runs southbound through Duran at 2:07 am, approaching at 80 mph.
If you zoom in the image, you might notice a flashing effect from one of the train's lights. That is from what was called a Mars-light that wags in a circular pattern which gives a flashing effect. Trains running at high speeds back in that day and time would have a Mars-light going. They didn't have the three light configuration back then.
