So this is the status so far. The front part is nailed and glued down, but the point leading to the goods shed need some work as the point motor gets jammed and stops the point from going straight. So that needs gentle removal (it's nailed down) and some drill work!

Everything beyond that point still loose, but you get the idea of the track plan. Underneath there are a bunch of SEEPs, and as this is Setrack, not too many wires. For isolating sections I'm always disabling the right rail so I hope to be able to reduce the number of wires required.
