These may soon come to O scale

I E-mailed the guy who makes them and he said he was planning an O scale version.

A couple of small magnets, a hank of stiff cord, and a dab of CA glue and you're all set.

I'm not from Missouri, but I sure would like to see/know how they avoid having these bi-polar snakes duke it out with either Kadee coupler trip pins or the magnets under/between the rails.  Which, of course, is another good reason for Kadee to get cracking on applying their remote uncoupling system (recently announced for G & #1 scales) to O scale, eh what?  No more trip pins, no more track magnets.

 I need that help line up in the top right corner!!!

KD, you'll notice they conveniently removed the Kadee coupler trip pins and they're manually uncoupling them from the top.  Probably for a good reason...

trainloon,

I like them.

I know, I could make my own, but these look and work smartly.

Got enough snow up in the Pocono Mountains?

OK. You can get 2mm mini magnets pretty easy but what kind of tube? Poly tube or solid rubber.
