Well, the hardest part so far, was getting the panel laid out for drilling the holes. I used 12v lights from China/ebay, Oak brand rotary switches set up for two positions only, these were scrounged from my ham radio stash, I ordered the knobs from Allied, and had Specialty Stamp & Sign in Florida make the vinyl switch plates. The color (Rustoleum spray can) is the closest I could come to the pictures of Union Switch and Signal panels that I have seen in pictures.The wiring will be the simple reverse polarity offered in the Tortoise instruction sheet. I figure this and a meter panel showing the voltage and current for the street lights, building lights, etc, and another for the DCC "juice" will give my grandsons (and me) a little more reality feel when operating. I will also be using Ron Paisley detectors to light the track plan on another panel that I have yet to build.
