Following some trial and error  the track plan for the 009 terminus became a reversing triangle with some small siding capability. The point actuation is by buried Peco surface point motors and it was designed to break up into 4 bits with all of the pointwork on the single middle section. Hopefully Its an operationally fun take on Twyn wharf

The base was 2 x 10 mm insulation material glued together. The track was all Peco settrack, other than a bit of flexi for one side of the triangle to give a bit of a wobble to one side and avoid too much straightness. I originally planned to have  Y at the top end, but as it was electrofrog it added some complication so i reverted to asymmetric RH - LH points only. One corner was isolated to prevent shorting and the power fed through a DPDT switch. The remaining track was wired with a huge amount of redundancy as the electrical contact at the points was found to be a bit suspect. 

Either way, for something so simple this took an inordinate amount of time, but somehow the result seemed more precise than the OO loop where every position was a compromise.
