I found a trackplan for an HO scale 5x9-foot layout in an old issue of Model Railroader. Named the Jefferson, Memphis & Northern, it depicted a shortline railroad in the southern United States. I made a photocopy of this plan, and did a little fiddling & finagling to adapt it to N scale, and the results are thus: This is a plan for a 36x80 inch hollow-core door, drawn with Atlas' RightTrack Software and colored with Microsoft. It depicts a railroad set in the mid-1950s using either steam or diesel. The solid black line in the center is a scenic divider, although you could put a ridge in the same place and use plenty of trees.The track at lower right serves as an interchange to the outside world (on the HO plan, it was the Illinois Central, but you could have it as, say, CSX or NS in the present day).
Nice workable plan, and I agree it looks like it fits somewhere in the rural southeast. My first thought was that of a rural branchline with lightweight steam local freight serving customers once or twice a week. Maybe with daily runs, but serving a different customer on each run. I assume there's an interchange with a class-1 off the HCD at the lower right.
I like it! just the way it is! Still you may want to consider: Upper Left - put a cut on both sides of the track. Then again I guessing that scenery is still in the planning stages. Lower right - push the interchange turnout back, (to the left), about 2 track lengths so you could store a car or two.
