So, I thought I'd post probably the least helpful items first (sorry). These previous versions just happened to be the first things I ran across and are for a former house with an 11'-0 x 15'-0 office space that I was going to use for my railroad room. We moved before I could even start, but it was a good exercise.
The constraints are going to occur at the same places - the corners and turnback loops. Straight track on straight bench work is a no-brainer, but working out where the corners fall in a track arrangement is something to really consider. There is probably an article in there about strategies for using corners and turnback loops cleverly. Let me know if anyone writes it before I get around to it...
An interesting note is that the viewer will be using a vertical staging device to replace Weehawken Yard similar to my planning to use one to stand in for Croxton Yard before it gets built out. Great minds, I guess. I'll dig up my vertical staging article from the LDJ at some point as well.
Anyway, more useful items to follow under 'separate cover.'
