1: California Northern 203 pulls a cut of coal cars
        
        
          slowly over a shoofly in Sonoma on a sunny California
        
        
          spring day.

          What a great idea for a scene on a layout! The scene doesn’t
        
        
          take up much room, requires only one turnout, and provides a

          story, a snapshot of something for the viewer to participate in
        
        
          rather than just telling him or her to enjoy what’s finished.
        
        
          Armstrong’s shoofly sketch stuck in my brain for quite a while
        
        
          as I built some small practice N scale layouts. The largest
