I do think Steve is on the right track here. The train regulator varies the voltage, but the RCX output can't. So you are left with managing (nominally) 9v pulses. But there is another solution. You could add a DCC decoder to your train motor, and (...) (19 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)
