@Vernon Barry posted:Well a minor issue is you said earlier DCS was only on the center rail and IMO that is wrong.
DCS is a signal embedded in the power on the rails. So no, it's on BOTH rails middle and outside.
TMCC is a radio signal. A lower frequency one, but a Radio signal. That radio signal, the outside rails form one half, the house wiring is the other half.
DCS is an in-band signal and again, is the difference between the 2 rails electrically.
In my case, I had a bunch of PS2 locomotives become unable to be found by DCS (even though they were already in the remote), until I swapped the wires at the lockon. The one diesel that continued to function was a PS-3 unit. I hadn't suspected reversed wires because that particular unit was the only one on the layout before and after some wiring rearrangements that ultimately reversed the sole track connection, and being PS-3, it didn't care. But the PS-2 units did.
