As I build the trackside industries I want to be open to the possibility that I may want to work a small camera or video camera in at some point and photograph the back side of the structures.  That means detailing said back sides.  I continue to chip away at the 4300 District Blvd. structure.  Shown below is the detail on the rear side which includes brick sheet, Grandt Line doors, and styrene columns.  The roof is .050″ acrylic sheet from the Home Depot.
