This photo shows the right end of the layout and the industrial area.  A concrete abuttment surrounds the area and provides a return loop for trains on the upper level.  In this photo, you can see that the factory buildings are somewhat undersized.   This provides and interesting forced perspective that can best be seen in the photo of the industrial area itself.  Also worthy of note is the use of a Gilbert #35 Brakeman on the rear of the caboose about to pull through the elevated station.  Click on the photo for an enlarged view.
