Jeff: Thank you so much for the explanation. I believe I understand, at last. As I said I am a real novice at this electrical stuff & I don't want to electrify ME or weld my trains to the track. One other question. I will still electrify the rails in the WYE complex just as I would any other rails elsewhere but they are all electrically isolated because of the insulated rail joiners but are electrically "correct" because of the reverse loop module that only needs to be connected to the tail of the WYE and will electrically supply the proper polarity as the loco passes thru. OK?

Jeff: Thanks for your response. I have just started back into model RR so am not familiar w all of the new stuff. However, I do like the Bachmann system and am going all the way w them w DCC, EZ track and stuff. When U mention switches are U referring to turnouts? I suppose so. I will b using their (Bachmann)reverse loop module since at this point cost is not a factor. Therefore would I b using a reverse loop module on each leg of the WYE after connection to the main line? Thanks for your help. dbowers

to use a WYE for reversal of locomotive in DCC, EZ track, should this setup require a reverse loop module on each leg of the WYE? I have the main line horizontal, then have two turnouts (L & R) going up to the two curved legs of the WYE, then the straight leg going striaght up the length of a full train. After going thru the right turnout & then up the right leg of the WYE & straight up the full length of the train , I then reverse the train down the left leg of the WYE thru the left turnout to the mainline. Now the train is reversed.
