This was an experiment. I'll have to go out and do it again switching to full manual exposure control. Each one of these pictures had slightly different exposures resulting in slightly different sky and grass colors and contrast.
July 25, 2008: I've lived near here for a long time and knew the trains were frequent in the evening but I never realized how close they were. Here are 4 westbounds running on 10 minute headway plus one eastbound (#169). I missed one as I was walking down to the tracks and blew another shot 10 minutes after the last one here. Threaded in between this there were 2 UP freights as well!
Went back to my in-laws for dinner and could hear the parade continuing. Wish I had brought my scanner. It would have been very interesting to listen to.
