I didn't understand where you were going, Joe. Problem with qny of those sequences is that they have to be done without a DCS signal on track, from trasformer not remote. This prolongs the procedure when you want to use or kill a loco.
Th situation I experienced was odd: When I' activate the loco in #23, the loco in #13 sometimes would react. I exchanged these 2 IDs with 2 from kther locos, and never had the problem again.
