I have two loops on my lay out that I have been running separately, one powered thru channel fixed one and the other thru channel 2 fixed. Now I have put in switches so I can run trains switching between the inner and outer loop. Is it safe to leave the feed from fixed 1 and fixed 2 connected? I am worried that it could possibly backfeed between the two channels and hurt the TIU. For what its worth I feed each channel from separate sides of a ZW transformer.
I think I am worrying to much but with the scarcity of reasonable TIUs I don't want to hurt anything.
Thanks
