... degree crossings. 726_201440_400000000.jpg My wiring diagram above was simplified as I'm using DCC with the same power block for the whole crossing And assuming either all N-S travel or all E-W and switching the whole section accordingly. Nevertheless, trying use bare wire due the shallow depth of the street sections, still caused construction problems where two (or more) wires needed to cross over. In the end I realized that a simple 2-layer PCB, using heavy current tracks, was a much easier and simpler solution. 726_201406_300000000.jpg Here is the the test PCB that arrived earlier this week. The PCB track spacing is 2" for 00/HO. The PCB is the same exact size of the crossings section and will be just screwed in underneath. The droppers from each of the crossing corners will pass down through the large plated thru co-located holes to be soldered. The 4 smaller holes on the LHS allow my bare wire connections to be made, without any crossing over wires to worry about. The layout of the PCB is such ...
