Hi. I have Atlas switches and track. You need to put power feed on all 3 sides of every Atlas switch. I did this and no problems at all. All my trains run really good.
I have come to that conclusion. Especially with this particular switch. It appears to be an older version switch. It is stacked with another switch which can’t allow the 2 to be isolated from the other without modification. No big problem at this point. Will see how it progresses after I I talked the TIU on the DCS.
