Hello! Is there any good alternative for remote uncoupling Märklin Z uncouplers? The standard uncoupler seams to be decent, but it is rather large and expensive. I have seen rumors in old forum threads about something called "system-joerger" and that it apparently involves gluing small pieces of metal to all couplers. But I have not managed to find out anything more regarding how it actually work and its reliability and limitations. Anyone knows more about this or any other solution that doesn't involve replacing all the couplers?
