The Portsmouth Branch of the PRR existed for about a decade in Albuquerque, NM. Its various sized modules were cut apart in 2011, and transported to Oxford Ohio for about eight years, and then transported again to an attic in Decatur, Alabama. The modules were then transported once again to the attic of a garage in a second house in Decatur. I may move again before beginning to re-assemble it or starting anew. This is a large layout with some 1100 linear feet of track and some 90 switches, all but two within easy reach from the aisles and thus manually operated. The mainline accommodates six trains running about ten minutes apart on what is a simple loop folded a few times. This is just a PDF file to get the layout online quickly.
