The problem with 12 gauge wire is it will snap if you bend it and if you hook it to a powerpack and you don’t have a resistor or transformer on the end your accessories and locomotives will overload and you will be left with melted electronics. I have also made my own scratchbuilt signals with diodes. also from radio shack.
