QUOTE: Originally posted by mondotrains Mike, Good question! I was really stubborn on my first layout and thought it was prototypical to never reach into the layout to manually uncouple cars. I therefore installed Kadee permanent magnets all over the place, including my yard. Well, on my second, and much improved layout, I am using an uncoupling stick (there are also magnetic uncoupling tools you can insert between the cars) to manually uncouple cars everywhere that can be reached easily. For spots that cannot be reached, like in some of my industrial sidings, I will use uncoupling magnets. Like another responder mentioned, if you place magnets in yards and on the mainline, you will have cars uncouple when you don't want them to. Hope this helps. Mondo
QUOTE: Originally posted by SROC99 ..."Delayed" and "nondelayed" uncoupling is based on the width of the magnets and not the actual couplers (as "jsp" has incorrectly stated), all Kadee couplers will operate with delayed or nondelayed uncouplers. A magnet that pulls the couplers open enough to uncouple and wide enough to pu***he opposing couplers back together over the magnet and not have them hook up or couple again is called a "Delayed Action" uncoupler. An uncoupling magnet that only opens the couplers just enough to uncouple them and no farther is called a "Nondelayed" uncoupler. Kadees HO #312 uncoupler is our only nondelayed uncoupler and the only difference is that it is narrower than the other magnets...
QUOTE: ...Using permanent magnets takes a bit of operational learning. The problems most modelers have with them is when they have unwanted slack over the magnets. But if you are willing to find the causes and correct them, then you certainly can use permanent magnetic uncouplers on your mainline as well as anywhere else. Kadee first marketed this system in the late 1950s and thousands of modelers use it without any problems at all...
