No major progress over the last fortnight, just a slow and steady plod...

The key task is to mark out where to cut the upper level board, as a friend is coming to help out this weekend.

In the meantime, I've been lifting the points (again) and fitting wires to the bottom of the frogs with the intention of adding polarisation circuitry at a later date. As the point motors don't have auxiliary switches I'm intending to use a little circuit with a latching relay to do this.

A friend of mine is using these circuits to control signals and these seem to work nicely. They should work well for the frogs too...
