When I had completed and sold my n scale Rocky Mountain Sub, I made the decision to build a new model railroad based on the area in Eastern Wyoming known as the Powder River Basin. I completed the bench work and some of the scenery base, but that is as far as I got. At the time we were in the middle of moving to a new home, and during that time I changed my mind about the size of the layout. Instead, I built and completed a 4'x10' design which became the n scale BNSF Orin Line model railroad.
The original design was 4'x14' and used two sections which came apart in the middle. I used ripped 1"x6"s for the bench work frame and glued foam insulaton on top to create the scenery surface. The legs were built to fold for easy transport. I was fortunate that a friend of mine was able to use the completed bench work, and still operates on it today. It was transformed into a desert theme, and was later relocated to the desert southwest with a move.
