I installed a Walthers Shinohara HO code 83 DCC friendly #6 3-way and it did have one quirk that “Middleman” pointed out in the attached thread; i.e., one teeny piece of track tended to get hit by wheel flanges when the route was another way, causing a short. Mine suffered the same symptom. I believe Middleman de-powered his piece, whereas I painted the offending edge with some clear nail polish to address it. Don’t know whether to blame the track or the loco flanges vs standards but it’s something to be aware of. Not saying don’t but this one, just be aware of a quirk to address. I would go the same route again as the item fit my layout desires.
