allthough this thread is a bit outdated, I want to show you my testresults with magnets for the Dapol couplers.
1. I had best results with decoupling and pre-decoupling when positioning both magnets outside the track
2. pre-decoupling is possible only if the extension is wide such that the coupler does not lock if the wagon is pushed away. Therefor you will not succseed if the magnets are positioned inside the track.
3. the magnets can be well covered with ballast (last pic)
