As the layout will have 2 points out the front and they are Peco Electro-frog point I needed to switch the frogs polarity I decide to make some sort of real ground through. I fiddled around with slide switches and the like but have decided to work on using a mini toggle switch with some extra brass tubing etc. Here is the results so far.
It's still a work in progress, but I like the way it's shaping up.
The PC Board will be below the scenery level. The hole near the bottom of the PCB is where a screw will be used to anchor everything to the baseboard firmly.
