GRJ, you provided one clear deal killer, Legacy/TMCC nonfunction.
Wonder how Right of Way unit performs re: internal V drop under load? Anyone know?
Next step is checking 180W brick on that score.
Then: Would a simple 1:1 isolation transformer used with said Variac solve concerns and not add significant V drop given absence of internal complexity of Z4000 and others? If brick idea fails, that would be next consideration.
Re: “get yourself a small bubble level that's only 5"-6" long and move it along the track in the problem area. It will tell you if the track itself is bowed.” If you visited you’d understand that doesn’t apply. These are long,perfectly flat and level sections of slowing where only voltage can explain the behavior. Please let’s not belabor that any more.
The switchable sections are a last resort. Not what I would choose to complicate an operating session. But thanks for the thought. Won’t forget it until something else works.
Thanks for the continuing help, guys.
