I'm using a borrowed design prototype from another post here - don't recall
enough to credit them right now - but it's a motorized technic beam jutting out
perpendicular to the track, intercepting the two magnets and forcing them
apart. Wait - I just remembered it was Rick Clark's design. Check this out:

(beware of direct links to xoom sites, however. Try his base page if that link
fails: http://members.xoom.com/jrickclark/index.html)
This is new to my design and integration into the RCX - I was using Kadee
fitted couplers, and backing over a magnet embedded into the sleepers of the
track below. The magnets forced apart the Kadee couplers I had attached to the
wheelsets and bogie plates of the LEGO train cars I built, but that wasn't pure
enough (or able to withstand the onslaught of my two young sons) so I'm going
with the technic beam-on-a-motor approach.
Here's more on this subject: http://www.lugnet.com/trains/?n=3529
I'll work on some photos, RCX export code via NQC, etc. and try and post ASAP.
Thanks for your patience...
