Jon, thanks for the response. Your suggestion has me intrigued, and brings up another thought! I assume you’re talking about wiring the trucks of the same boxcar together, and not between cars, which would defeat the purpose of having the ability to fire the elector-coupler to drop cars out of the consist. I can certainly try that! My other thought though is if powering the operating track from my accessory transformer rather than track power would cause the issue?? There’s a voltage disparity there for sure since the track is getting 18V and I have my accessory transformer at 14V so the milk cans don’t get “launched” across the delivery platform. That said, if that were potentially causing the issue, I could revert to powering my Uncoupler/Operating tracks from the 18V track power. I can assuredly state that the transformers in my layout are all in phase, and have a jumper wire across the ground of all of them, so that shouldn’t be an issue. Your comment got me thinking about the track power situation though. I also checked the power rollers to ensure they’re not making contact between center and either of the inner rail pieces, and they’re not.
I appreciate your thoughts. This is why I LOVE this forum. We share our problems and our successes, and we all get a little smarter! Thanks again!
