Sorry I didn't reply sooner, but I have been tweaking the final concept. I have just added 3 more photos of my schematic. The "Final concept" schematic should be read in conjunction with the other 2 schematics attached in the photo album.
As I have 4 turnouts in conjunction with these schematics, I am intending to put the wiring for all 4 on one PC board. The final wiring is on the "Final concept" schematic. I would appreciate it if you think I would be better off doing 4 single PCBs instead of the one PCB, and if the wiring of all 4 is correct by adding just one 12V DC supply to all 4 circuits. There are 2 bi-coloured LEDs attached to each turnout, 1 bi-colour shows GREEN (default) the other should show RED, then when the original shows RED instead of GREEN, it's "mate" should show the opposite colour I I hope that all makes sense.
Re the brightness of the LEDs, as each resistor will be controlling 2 LEDs, for now that doesn't concern me to much.
