Yeah, I kind of thought it might be hard to open the motor without damaging it.
I guess I'll bite the bullet and get one so I can try it. That means of course
I'll have to buy about 20 service packs worth of track (-:

I saw that some people were using springloaded power contacts, but it doesn't
solve my problem of making the motor turn on and off. My project won't work
unless the RCX can turn the motor on and off at its own choosing, to control
the movement of the entire assembly. That means, even with power pickups, you
still need to get at the motor's wires so the motor can be controlled
seperately.

Yeah, DCC is great, and I'll probably use it someday for my HO layout [1] but
it's sort of a move in the wrong direction for my LEGO project. I don't have to
send any commands to the mobile platform, it will be entirely autonomous. And,
the platform will have sensors, which determine how it behaves. Since DCC uses
a one-way communication protocol, that is difficult unless the DCC controller
is on the mobile platform as well. Also, buying six DCC receivers and a
controller (and then learning how to program the controller) is overkill when I
can do everything I want with the RCX and LEGO components I already own.

two analog controllers, and about a dozen steam locomotives from the 1940's and
1950's meticulously hand-made by my grandfather. It's partly because of being
used to HO scale that I'm not too interested in LEGO trains -- they're so darn
*big* (-:
