Chuck Davis’ HO scale Lehigh Valley RR, Dual magnet uncoupling
Looks good. After making a couple of set offs in a track can you lift the full track or are all the knuckles still in the offset position?
Hi Dean. They will act the same as Kadee’s delayed action in that if you back up slightly, you can push the uncoupled cars down the track and the couplers will be left in the centered position. Only the couplers of cars left at the magnets will be in the offset position. To couple onto them they must be pushed past the magnets, back up slightly, reverse and then they will couple.
Thanks, I wasn’t sure about that. You have a great looking railroad, thanks for posting the video.
Where can I purchase the dual magnet uncouplers mentioned in the video? Also what is the manufactures model or reference number?
Melvin, the ones I used were purchased from K&J Magnetics (kjmagnetics.com) and I used the D24’s which are 1/8 diameter x 1/4 long. The article I wrote on installing them was in the 11/08 issue of RMC. The critical point is to keep the top of the magnets 0.030" below the rail height. This should prevent them from effecting loco axles and steel axles passing over. And of course your trip pins need to be at the correct height using a Kadee coupler guage. Try a dozen or so and see if you like them. They’re relatively cheap.
