(...) Well yes, that goes without saying. You need to protect your DCC function output from exceeding it's milliamp limit. With the Zenner it just makes your resistance required to be far less. As an example 50 ohms as apposed to 200 ohms. Dean (21 years ago, 9-Feb-04, to lugnet.trains)

(...) Well that is currently the only way to pass power. But it's very inconvenient. Hence the call for something new. Dean (21 years ago, 9-Feb-04, to lugnet.trains)

(...) Just remember to limit the current through the Zener diode when dropping the voltage... If you have a 12V supply and try to put a 9V zener without a dropping resistor, it will simply burn out. A zener diode is really a clamping device. Better (...) (21 years ago, 9-Feb-04, to lugnet.trains)

(...) If you modify the motor to pass the rail signals through to the power port on the top of the motor, can't you just use standard LEGO wires and connectors between the loco and the cars? Ralph (21 years ago, 9-Feb-04, to lugnet.trains)

(...) I've done onboard RCX to modified train motor before. I had it read barcodes along the track to know what station to go to. (URL) motor now powers my DCC CN engine. One thing I would suggest is to get a 4.5 volt Zenner diode and put it in into (...) (21 years ago, 9-Feb-04, to lugnet.trains)

(...) Consider also conductive paint on plastic wheels. It may not be a good permanent solution but would allow for experimentation before commissioning tooling to create metal wheels. (21 years ago, 9-Feb-04, to lugnet.trains)
