Bach-Man: Forgive me if this has been already addressed (and please point me to the appropriate thread(s) if so), but I have been captivated by the SPW layout ever since it appeared in the On30 Annual.  Is there anywhere to locate the actual track plan other than the photo spread in the Annual article?  I'd like to import it into TrainPlayer to experiment with it and (ideally) into the RR CAD program 3rd Planit as well to tweak it for may available space.  Too, it would be great if a more detailed story could be presented in one of the modeling magazines about concept, design, construction, operation and - most important - lessons learned from the project (what went well, what would you change if redoing it and why, etc.).  I (and perhaps others?) would eagerly devour anything you care to share about this project.  You did a great job on it and for my purposes, it's a winner.
