Pdaitabird Posted January 8, 2019 I wanted to share this simple decoupler with the community. The advantage of this type of decoupler is that it actually separates the magnets rather than just holding back a car by its wheel, so there is no chance of the train separating in the wrong place. Mine is activated by a hand crank, but the output shaft could easily be connected to a motor. The photos should give you a pretty good idea of how to build the mechanism. I hope others can make use of it!

dr_spock Posted January 9, 2019 Nice work. Is there a way to make it so that it can move a bit parallel to the tracks so that you don't have to stop the train perfectly on the spot? Share this post Link to post Share on other sites

Although I haven't tried it, you could probably mount the whole assembly on wheels to roll on a narrow-gauge track beside the mainline. Share this post Link to post Share on other sites

That might become tricky: As the coupling is broken up by pulling the train against the decoupler, it is required that the decoupler does not move parallel to the track.
