It's a good reference, and I'd probably scale it back some to fit table
dimensions.  There's an incongruous electrical connection that needs to be
removed, however, as you've got polarity reversed on the right end of the yard.
The right-most switch on the 2nd-to-bottom siding shouldn't have a siding that
connects to the outer line.  Check out the .tdl under View>>Electrical and
you'll see what I mean.

Thanks for playing out the theory - gets the gears turning...

A1. Two points with a diagonal straight in between can be used to

A2. A right, 12 straights, and a left will be close enough to keep the
    tracks "in sync".  (Ditto for left, 12 straights, and right)

Here's a yard layout I worked out that I worked out using these
principles.  It's available in both GIF and TDL (Track Designer
Layout) formats.  PLMKWYT.
