Why single sided copper clad PCB initially?
Initially we planned to use the bottom of the PCB (copper
exposed surface down-top of Tortoise) as a way to help reduce
the number of feeder wires one would have to run to a turn-
out. We were using BK Enterprise turnouts with PCB ties.
Instead of six separate feeder wires for the two points/closure
rails and two stock rails, and two more for the Tortoise SPDT
contacts to flip frog polarity. We were to isolate the copper
clad into two halves down the middle of the board, drill holes
where the rail was to run (through the PCB ties) and run short
feeders, soldering the bottom of the feeder to the copper clad
and then thread the feeder up through the PCB tie right next to
