In Cincinnati the right hand wire was positive and the left hand wire 
negative.       The PCCs run the suburban sections with the left hand 
pole down.     As for the ZOO loop, I assume the left hand or center 
(negative wire) was shared by both directions while the positive (outer 
wires) were for each direction separate.      That's also why the center 
wire does not have section insulator while the outer wires do have.

Those items in the outer wires just behind 1166 are simple trolley 
collector contactors like Pittsburgh used for Nachods  --  they are not 
insulators.       These contactors just pass the current from the wire 
to contactor and to whatever is connected to that contactor.       This 
gives more credence to my  'assumption'  that these are dedicated 
contactors to set the turnout track for 49 - right wire  (left from our 
viewpoint)  to go into the loop  and the left wire  (our right)  sets 
the turnout for the 78 to go straight through.

I went to the website to get this message which never arrived 
here.       I have since sent in a drawing and map of this location 
which has Not shown up here nor has it shown up at the website.

VERY___Interesting your comments about polarity and the PCC  --  the 
Muni older Flyer TCs were simple beasts but the electronic  ETI's  are 
more PCC-esque and I wonder about polarity reverse in relationship to 
them.       We do still have some overhead like that here in SF;  we 
just had a discussion about same on the SFMuniHistory list!!!

Now,  Lettuce see if this goes through  --  And When  --  If-Ever!!!
