Laurence was in deepest Dorset visiting family, so just Geoff and Stephen, who spent the morning going through all the paperwork that was available on the board electrics. Progress was made unravelling the basic wiring, but it was a struggle making sense of some aspects. The rest would have to be resolved with the boards in front of us, in due course.
The exchange area between the main and local control panels switching system that Stephen had produced was examined - Geoff had never got to grips with the system as he and Stephen have different ways of working out and documenting such things. Once explained, Geoff identified a potential problem, but was able to propose a modification to overcome the issues. However, this had different, but less onerous issues that will need to be examined fully, in due course.
After lunch, the wiring on the 4 adapter boards was examined. One was complete, with the loom socket fitted and wired in, and tracks wired to a 5-pin din socket on the side. This provides feeds to the switching box where the Controller of the Mainline (inner circuit) and Fiddleyard (outer circuit) on the change-over section are determined. The other three boards were completed (not without some self-inflicted pin-identification problems), which will allow an extended test run tracks.
We cut and glued some wood, screwed some electrical bits and soldered some wires - we did some work on the layout!!!
