Could A 3 Pin Digital Decoder Be Made?

hmm.. that image shows the standard 4 wires on the ZTC decoder: black, grey, orange, red. ( I found that image earlier).

Don't disbelieve you, just curious to find out more!
 
Zero 1 "Decoders" / Loco modules were indeed 3 wire.

The dual mode ZTC decoders (DCC/Zero1) needed a 4 wire installation.  One sentence from the ZTC installation guide is....

"If both brushes cannot be isolated from the track voltage pick up connections on a particular model, the locomotive cannot be fitted with any DCC decoder."

Track Wave forms....

Oh and just for your enjoyment, here is a schematic of a Hornby Zero 1 loco module...

Muns...thanks for the waveforms.....I've never seen the zero1 before, nor the circuit diagram for a Hornby module ( there were two distinct types, and a variation for USA/Canada..60Hz! )

I'll still look from time to time for the mythical ZTC 3 pin zero1/dcc....maybe they were going to make it, but like much of ztc, it came to nought.

Anyway, with only 3 wires, there wouldn't be any function outputs for lights etc

Back to the clockwork trains!

Well well we live and learn. But still back to the mythical 3 Pin LGB Loco. Would not be a simple 'Plug it in Job" you would still need to do some mods to the Plates inside the Clamshell or whatever the oldie is. Thus you may just as well go the complete Hog and turn it into a 4 Pin Effect - as original, now it would not be.

I've just received a reply from Massoth who tell me that they don't think it would be possible. It was worth a try :)
