Reply to "Running PRR signals - how to wire"

Stan, thanks very much the explanation of the 1/2 wave conversion makes complete sense now...

I really wasn't thinking about pulling my 12 VDC signal relay power directly off the track... I was kind of thinking about providing the proper 12VDC voltage off a spare post of one of my 4 PW ZW's and running it through a full wave bridge rectifier... If I do this, and I have all my common posts tied together, I should be able to close a block relay anywhere on the layout once the train enters that block's insulated rail ... Does that seem like a wise way to go, or am I dreaming ?

I don't run DCS, I do run TMCC and Legacy control on the layout.... Seems like I should still install the 220 uF capacitor on the relay power bus to stop chattering, and I can ensure that I am not putting anything over 12 VDC out to the relays on that bus line.....
