After completion in the workshop I got the good wife to assist and it was moved in and attached.
Now that this centre module was in place it allowed me to work out the curve for leaving the terminus station area so I could try my earlier full scale planning diagram.
While all that was happening I had some time at the work bench and started the wiring looms for under each turnout. Nothing flash, just a simple wire activiation from the side of the layout. I think you have all see it before.
