I've wired the layout now, and I'm quite proud of the result. It looks neat and tidy underneath, and there's a feed to all areas.

I've run my Bachmann 03 very slowly along all the routes, so that's good. I'll do a video in the daylight to show just how slowly it goes, and also show off my wiring and plug/socket.

I'm going to bed now, to dream of more things to do.
