the high iron. Still, I'd had 9 years to get used to global visibility
        
        
          in the train room so it was a bit of a shock.
        
        
          One other good thing – I'd been concerned that the aisles
        
        
          would seem much narrower once the upper deck roadbed was
        
        
          installed. After all, we tend to be widest at the shoulders. I was
        
        
          pleased to discover the aisle widths seem to be workable. This
        
        
          was borne out during the most recent op session where the
        
        
          upper deck didn't cause any aisle width problems.
        
        
          At first I thought the backdrop was reducing light on the lay-
        
        
          out by preventing light from one row of fixtures reaching other
        
        
          areas – it felt darker. Now I don't think that's true. Once the
        
        
          final backdrops are installed and painted, I expect the light
        
        
          bouncing off them to equalize the layout lighting intensity.

          4: Albany Junction on the left is taking shape on the
        
        
          banks of the future Santiam River. The aisle here is 36"
        
        
          wide. The backdrop isolates this area from Bear Creek
        
        
          yard (behind it) and the area around the corner.
