Update on my LEGO city -- skeleton of a corner

Once again, nothing you see above should be considered final at all, but this is showing the general idea of the shape & rough arrangement of one corner of the layout.  The train yard and port have been laid down exactly as they are in my digital mockup and they feel "right."  Both are on a siding off the main line, so there's a little extra room for switching even when other trains are in continuous operation.

Again, not final at all!  This is called work in progress!
