I was working on a hump yard decoupler and was playing around with adding mags
to the track using the 2x2 tile that has clips to hold the mag. What's really
cool is how you can make a train car hop over the mag on the track. All this
play was big fun and was experimenting in creating a magnetic cat whisker or
pseudo reed switch.
another thread: Can any one say mag lev....
BTW we had a really nice guy visit a PNLTC display in Seattle that had a
wonderful and very clean and simple solution to the decouplers. It used a
rubber band limited rack driven by a motor. Ir pryed the couplers apart using
a stubby tappered technic beam at the bumpers.
DanParker do you recall his name? I unfortunately have forgotten!

| I recall somebody posting pictures of a design that sounds like the below here (or maybe on RTL?--but I'm pretty sure it was here) not tooooo long ago. I think the stubby tapered beam can be had for example in the red Technic chopper that's been on (...) (24 years ago, 6-Jan-00, to lugnet.trains)
