I modified the layout (eliminating entering Pit lane difficulty). Along the way I did check ALL digital pieces for internal jumpers, and found only the Control Unit uses them. Parallel lane paths were corrected using better bracing in high banked curve sections. Spent a little time in upgrading MY Carrera track manual to include little known track piece Part Numbers as well as dimensions including slot lengths, and footprint sizes.
Currently, testing wiring concepts before securing layout in place. Complete new wiring is being done to ensure all is proper, starting from the power source, then the Analog controller circuit (standalone) and Digital side. Will be conducting ANALOG testing without the Digital Control Unit in layout, once it operates correctly I'll swap the Control Unit in and check the Digital side. Hopefully the modifications to eliminate the internal jumpers that provide crossover (both lanes powered from a single source) will be corrected using a 4 wire harness providing independent (although identical) power to both lanes from the Control Unit.
I'm attempting to wire two completely separate systems  with a common power supply (Both Analog and Digital) both using their own set of controllers. Isolation is accomplished with a DPDT knife switch which allows only one or the other to have power at any time. Back flow or crossover due to using the same Power Taps to distribute the power is isolated with using 10A10 diodes on the positive Digital feeds.
