Do reversing loops in 3-rail O gauge require polarity reversers or isolated sections of track? I wouldn't think so, since both outer rails are negative (ground) current.

Welcome to the joys of O3R!!
Reversing loops...no problem, no polarity conflict!
Yup - no need. The middle rail is always the middle rail.
That and insulated rail accessory control are the 2 reasons (are there others? inquiring minds...) we have the 3-rail track, in all its glory, good and bad. Christmas morning didn't need any more complications.
And all it costs you is an ugly middle rail at all times. yay!

Yes, but how much do 2 railers have to spend to get detection. Another 3 rail freebie. For me putting up with the middle rail is an easy sacrifice.
Also 3 rail uses AC power instead of DC, which eliminates polarity issues.

Don't have to worry about it with BPRC (Battery-Powered, Remote-Control) 
. It's not called the "Dead Rail Society" for nothin' 
Bob, you don't have to worry about reversing loops in 3-rail with any command or conventional running, I'm afraid that's not one of the "benefits" of battery power.

John, DC/AC has nothing to do with it. You could run DC 3R and still have no issues with polarity.
Only 2 Rail matters. G

I agree with GGG about three rail track, polarity is not an issue and neither is AC or DC an issue except for switches being wired in.
