• Pierre,
    I need your help. How do you address the DCC wiring and insulated rails for this diamond crossing configuration? I have them on my layout.

    • Hi Jimmy, that’s a nice crossing! I like Peco track, but the crossing are notoriously difficult to wire (as opposed to many other brands…where you don’t have to wire anything). I only have the “scissors crossing”, so I can’t help you directly.

      However, looking at picture 6 of the manual http://www.peco-uk.com/imageselector/Files/Instruction%20sheets/N%20Electrofrog%20Turnouts.pdf It seems you need 2 single switches PER crossing. Usually these switches are linked to your usual track wires (e.g. red black). In your case, my guess is: the switches for the “center” crossings (the 2 that are side by side) will have to dependent (connected) to the switches of the “extremity” switches (top, respectively bottom switch).

      Those “switches” can be either mechanical (linked to whichever motor option you have chosen for the crossings), electromechanical (a relay, separate from the motor but switched at the same time), or even DCC (e.g. a relay decoder, switched by the same address). For my scissor crossing, I am personally using the ESU Switchpilot decoder + the Switchpilot extension (which contains the relays).

      Let me know if that helps you a little. In any case it’s gonna be a small challenge!

      • Pierre, thanks a lot. I take a closer look at the instruction and try to figure out. It is easy when you have one but with 4 interconnected, I am kicking myself on the butt for making it so complex.

        You can visit my blog germaN160.wordpress.com for full track plan. Looking forward to your comments too.

    Hello Pierre,
    Thank you for this article, it was a big help to me. I like the detection loop modules and was curious as to whether you have learned of any products make in Canada or the United States?

    Thank you and Happy New Year.
