    I have one incorporated into a T-Trak module. Only problem is if we use a loop back we have to have the loop back on an AR circuit. To make the crossover work properly we need to have our tracks wired BWBW instead of the recommended BWWB.

    OMG!! It’s taken months for me to get these reversing loops and crossover working properly.

    First I was told to reverse the crossover itself. Then, when it was determined that that wasn’t sound advice, I had to buy another AR. Then, I assembled a rudimentary dogbone, just two loops connected to the crossover in the shank, and was having weeks of trouble trying problem-solve the faults I was getting.

    Then Rick Brodzinsky hit on my wiring scheme being the problem. I had it wired as though the crossover, set to ‘pass’, was the two straight sections of an oval (BWWB) and when I threw the turnouts to ‘cross’ it shorted in the middle of the crossover.

    Wiring it BWBW, as though the crossover services two parallel lines, was what was needed. Now it runs smooth as silk and I’m ecstatic about it! Lol!

    I tell people not to look under my module, just follow the colors on the plug. I had wired my modules for the standard BWWB before buying the crossover. After using a meter on the crossover I realized that this will not work on a T-Trak setup with the recommended wiring scheme.

    The first time I brought a module to a show one of the guys there looked at my white wire into the blue plug and blue wire into the white plug and said I had my setup wired all wrong. I tried telling him it was fine as my club goes BWBW not BWWB. He kept insisting I was wrong and the club (which he was not a member of, he was the member of another club setting up at the same show) was on the standard wiring scheme. The look on his face when a train passed through my crossover and kept going was great! Also he heard the click of a PM42 when I entered the loop back and then it dawned on him how we had our stuff set up.
