This one was based on the Ventura County Railway, which interchanges with the UP (formerly Southern Pacific) in Oxnard, CA. I lived nearby in Southern California at the time and it would have been a neat N scale switching layout in the oversized finished garage of the house I owned there (1989-1990 or so).

Bruce Morden wrote a great article on the Ventura County Railway in Layout Design Journal #26, Spring 2001, published by the Layout Design SIG. I reworked my design in 2001 for the article and looking at it again now confirms that it would have been an interesting layout to build and run, even if I would make a few changes if designing it today.
