Lever frame

And more or less done. Here with the upper structure dropped on.  Once you start scratching the surface, you open up the worm can. I started asking how many of each colour? AotC has four points so that's the black ones done, and I reckoned two FPLs and at least four signals. That filled the frame with no spares. I re-read Tim Rayner's excellent article in RM from a couple of years back and now I get the feeling that I probably needed about 15 levers as opposed to 10. Too late now, I shall never sleep again. Maybe some clever person could draw up a signalling diagram for the layout.

Because AotC is a 'model' and not really drawn from real practice, it probably needs ground signals on both sidings, which in essence means three FPLs as they exit the running line . There would be a Home beyond the bridge, plus the starter and another ground at the far end. Would the crossover be worked on one lever? Questions... but then it's barely visible anyway.
