An RCX isn't needed to control track power. Use the standard Lego controller
to set the speed. The onboard RCX controls a relay that is in between the
power pick-ups and the motor. This would require a modification to the
motor, though. But given that you are talking about bashing around your
bricks, modifying the motor shouldn't be too daunting <G>.
Another idea is for the trains to run in opposite directions. This would be
like jousting.

| (...) Well, yes, true. You're envisioning the train motor being directly controlled by the onboard RCX. Takes lots of batteries (which is a standard way to do things) However one interesting twist would be to have the train motor be UNCONTROLLED, (...)
