+Unfortunately the temperature and dampness of the garage that I was working in meant that this didn't dry quite as tough as I would have liked :(

 === Track Underlay ===
-Cork matting.
+Cork matting is typically fitted under all track sections to raise it slightly, provide a small amount of sound deadening and allow a bit of vertical 'give' between sections.

+One thing I learned from this process is that cork is a horrid thing to glue - it wants to curl and lift everywhere! Also, I really, really, should have made the top of the tunnel removeable!
+Sadly I made a mistake in the layout of the track which meant that I had to go back and remove one of the inner sections; the initial place of the track had one set of points directly over a board join, which was completely impractical.
+Here I've removed the cork matting and am ready to re-lay the cork at a slightly different location:

 Fixing, cutting.
+Where thr track crosses from board to board, it was cut and then joined with a brass tube and pin (soldered to the side of each rail), so that the track still joins both physically and electrically:

 Because there are 15 or 16 individual points, I decided to make a controller so that it would be easier to change them all from one place.

 Plastic enclosure marked up with where the switches will be located - they only cover half of the panel as the left half will be used to affix an image of the track and the numbered points, which will match the numbered switches.

+Starting to attach the wiring on the underside of the track boards; since all but one of the motors are on the central board, I decided to disconnect the outer boards to make it easier. Turns out that the track joining mechanism works really well, and the boards came apart quite easily:
