What can I say about this series? Trains and my life seem relative, and of course, the focus for me is the mighty engine. The engine must constantly be maintained to perform at a high level to produce enough power to pull massive loads. Perhaps we can become engines like this? This piece has many unique features, including sensitivity to light due to the metallic I used in the highlights. These are straight-up metallic, not the interference media used in my “Carbon Series”. — David Alderman
