Those vintage magnetic couplings were also sold in replacement packs and sometimes can still be seen today offered new in package... at a price of course. They could still be used on todays trains as they fit the same with 'T' end and Hole. They would be great for the remote controlled engines where you could remotely couple up rolling stock as long as it has a reverse.
