After discussion with the other half of the railroad management some additional modifcations were made:
Piers were swapped to facing point from Rigby to allow Yard 8 (the one at the top) to be moved down to provide scenery space. Track spacing was adjusted in yard 8. Minimum separation between tracks is now 1.88" (1 or 2 parallel tangent tracks), with most being greater than 1.92". Curve tracks are between 2" and 2.1" spacing will be adjusted if necessary, but I dont have any articulated locomotives, mostly small just small steam and 4 axle diesels, so this is less of a concern at the moment.
Lakes class steamer (Walthers) is planned to parallel to the pier at yard 8).
I reworked the SD Warren Paper company tracks to minimize the reach in, and make better use of the corner of the room ( the aisle was only a foot wide, and I realized there is a knee wall (actually a hip wall @39" that sticks out 1' on 3 sides of the room) so that 1' wasnt actually accesible anyway.
I appologize for the poor quality of the photographs, RR track software only allows me to export to BMP files. I could try printing screen to MS Paint.
