The purpose of the P & C Railroad version 3 was to have some long, continuous-running mainline track up fairly quickly, to be able to develop some scenery, and to start exploring doing some switching operations. When I started this layout, I was in a stressful job, so I wanted to just come home and watch the trains run-around. The original plan was just to have a double-track mainline loop around the perimeter of the room. When I built that, I very quickly realized that I got bored with it, so I started expanding the layout. I widened some parts of the layout, and eventually went so far as to build a ten-level helix down to a large staging yard!
