Well, it has been some time since I have posted - mea culpa, mea culpa, mea maxima culpa! I have been very busy with several issues but I have not neglected the layout.
I was able to buy a large number of commercial lighting fixtures at a very low price ($5 per) so I went around and put over 35 up in the place of the twin bulb shop fixtures I originally installed. This took a little time as I had to rewire some of the ceiling to rebalance the bulb count by light circuit as I was adding so many bulbs ( going from 2 to 3 and 4 bulb fixtures). I actually melted a light switch due to a slight overload. Fortunately, I was right there and no damage other than to the switch occurred. You can see in the photos that the light fixtures have full reflectors which made a terrific difference. I feel like I am in an operating theater now. It makes it so much better to work on the layout. So, all construction stopped as I was in the ceiling above. I located the higher intensity lights over the aisles and left the twin bulb units over the areas where the scenic dividers will go later. In the first picture, the light in the right foreground is a twin. The lights in the right distance are the new ones. They look like spot lights in comparison.
