I wanted to use rare earth magnets on a layout I am building right now to magnetically uncouple my rolling stock in the yard. I planned on using Micro-Train couplers on all my rolling stock and replacing the plastic wheels with brass insulated wheels from Intermountain that are meant for Micro-Trains trucks. I know it says they are brass and that should not cause any issues (like the wheels sticking to the track), but Atlas metal wheels are brass, but the axles are steel so I figured that might cause a problem. I have not been able to find out if Intermountain's axles are steel or not, but I figured I would just ask this question, who is running metal wheels and using magnets to uncouple their rolling stock? Also what type of metal wheels and couplers are you using?
Thanks
