We (the PNLTC guys) have been thinking about this for a while. How to remotely
uncouple cars. great challange. The magnets are so strong that it seems that
any upward motion would merely derail the cars (leaving them coupled but
laying on their sides). How did the old 12v decoupler work? It seems like a
mechanism would have to pry the cars apart. Without the "coupler pins" there
are dependencies on the rollinf stock type. Decoupling 2 box cars would be
much easier than 2 flat beds.
How about a radical approach. Redesign the couplers using technics part with
real knuckles... designed to be uncoupled.

| Okay. Here's the situation. Like many people who got into 12 volt Lego trains, I own a number of magnetic couplers which have little pins that stick down toward the track. It took me years to realize these were designed to interact with the (near (...) (25 years ago, 30-Jul-99, to lugnet.trains)
