Thats exceedingly cool. But since I dont have an RCX, it makes me wonder
whether something similar could be done without it. Perhaps a small lever
thats pressed by the train as it goes past, which is connected by a hidden
string to the heads? Or something that uses the weight of the train on the
tracks?
Probably not as easy or as good as using RCX, but it makes one wonder...
Anyway, super job!

I missed the initial post the first time I read about this, but my
first thought was magnets. My wife (a non-AFOL) thought magnets too
when I showed her the video. I've noticed the train magnets are strong
enough to make the magnets twitch on trains that have been parked on a
siding. The only issue would be getting the heads to reset back to a
neutral position. My wife's idea was to slant the MOC so that the
natural resting position was gravity driven, though I'm not sure the
magnets are that strong to overcome gravity. Perhaps a stationary
magnet repelling the moving magnet...
Just tossing out my 2 cents.
