a laser excites a single Strontium Atom, and it gives enough light off to be visible, with a long exposure, in this picture. it's the tiny blue dot dead center.
This model is from a SpanAm war era periodical. I up scaled and cleaned it up a bit, as it was closer to N than HO scale, and I wanted it for background with my Civil War figures.
pics from my Muskturtle Bend and Hidebehind Creek railroad. wonder if I still have the stuff in storage... the Walmart Battery train is great, but won't handle lionel points... Marx and old Hornby switches work fine.
