Not a lot to add for now, I've been busy with other things. Ford has taken the centre module away to work on the wiring for the Arduino, and is planning to mount a dedicated power supply under the board to handle the next stage of the lighting, sound and animation for the layout.
I do have some photographs of some of my purchases from Seaboard Southern though. First, three TTX 86' flat cars from Jason Dickie:
These will eventually become tri-deck open sided autoracks. Nothing like making life easy, eh?
Finally, a Lionel(?) truss bridge I got for £10 from one of the other traders at the show:
I'm going to have some fun with this one when the next stage of the layout comes along.
More updates when I'm able.
