Hi again Ted!
We're getting into a realm of 3-rail I've never explored before: Contemporary control. My previous 3-rail exploits were always built around the PW ZW. Looks like the MTH Z4000 Remote might be a good route IF I'm understanding it correctly:
* The MTH Z4000 utilizes a power source, BUT, it doesn't HAVE to have the MZ 4000 transformer as that source, correct? If that's correct, that would be a very cost effective way to get walk-around capability: Two Z4000 hand sets, and an adequate power source.
As for the Lionel ZW-L:
* Looks like it is a command control platform that CAN operate in the conventional realm. However, am I to assume it would need some form of additional hand held units attached for walk around capability? And boy, they are PROUD of that ZW-L! ($$$!)
Diodes/etc:
I would likely want to stay with good old power blocks (insulated track sections controlled by toggles or rotaries), and conventional walk-arounds. (I have boxes of toggles and rotaries.)
Thanks again. I appreciate you taking your time to help me understand control options.
Andre
