Thanks John, wiring will be very straight forward, just two very fine wires from each LED running across the bridge and down the leg. That's still a lot of wires, 18 to start, maybe more if I include block signals facing the other direction. From there they will go to a special CMRI circuit, one per LED, that will change the colors to R,Y, or G using 2 output bits from the computer. The computer will calculate the correct aspect to display based on track conditions and turnout positions.
