My pleasure. It is enjoyable to watch your system progress.
I understand your reluctance to use MTH units. Some, perhaps several, have numerous troubles of various types. DCS seems to be delight for some, and a dreadful bane to others. For my part, I have had generally excellent operation from my MTH PS3 scale locomotives. I run DCS 6 (I do not use the app or wi-fi, hence the lag in upgrading to 6.10) and have been pleased with it, minus a few quirks here and there. For overhead catenary operation, it has been all but flawless.
I will say that the E33 pan leaves a bit to be desired after extensive operation, so it will get replaced, (hence the post about MTH parts at York that I submitted this morning).
