Joe,
I don't know. I have no experience with standard gauge. You improve you overhang problem by increasing the radii, however the distance between track centers drops from 8.5" to 6". If this was all O scale then that would not be a problem as 4.5" spacing would suffice.
If standard gauge trains are fine with std57 and std72 curves (7.5" spacing) then I would feel confident that your initial plan would work and possibly this lastest plan.
I would follow Bob's suggestion.
Jan.
Kirk would agree that 7.5" spacing is precisely what SGMA adopted when we establish our required mainlines at 42", 72" and 87", plus an optional but normally unused 57" mainline.
