Sorry if this info is already posted (I tried search but no luck /DesktopModules/NTForums/themes/mls/emoticons/angry.gif). I want to try Kaydee couplers on some LGB, USA Trains and Great Trains cars and locs /DesktopModules/NTForums/themes/mls/emoticons/blush.gif. I'm hoping to close up the car gap a little bit as I don't use 4 foot R1 diameter curves. Can someone reference earlier posts, tell me how to search, or express their ideas. Most grateful, thanks!
