Looks interesting. How can they be uncoupled remotely?

Yes, interesting. Wonder if 2mm x 1mm thick magnets would work. Like these http://www.ebay.co.uk/itm/Zinge-Industries-2mm-Diameter-1mm-Thick-Rare-Earth-Magnet-N35-x-50-A-MAG01-/301938069087?hash=item464ce94e5f:g:NS8AAOSwgNRV8bmA (http://www.ebay.co.uk/itm/Zinge-Industries-2mm-Diameter-1mm-Thick-Rare-Earth-Magnet-N35-x-50-A-MAG01-/301938069087?hash=item464ce94e5f:g:NS8AAOSwgNRV8bmA)

Given the power of that type of magnet, you could probably get away with a single magnet + small lump of iron/steel sheet for each coupling pair. If you want to make the magnets a little easier to break apart *without* a Nerf gun (i.e. when lifting stock off the track), put a paper sticker over the surface to reduce the adhesion slightly.

I like the way the magnets help qthe coaches stick to the ceiling.

Seriously - Marklin have a wagon/ coach coupling system involving a vertically swivelling magnet ( mounted in coach bellows or the rear wall of a wagon) with a matching steel plate in the next coach / wagon.

I have wondered about trying an N gauge version?

Pics to follow

I still think that Unitrack jars the wheels where Peco does not but pre ballasted track and built in point motors won me over. I have ordered a je

If you are referring to the small irregularities between track segments, pressure from a small screwdriver is effective in sorting out your problem.
