[PRCo] Re: Poles to Pans

[Frederick Sauerburger]

Cool.
I pictured crews working their way south changing hangers until a loop or
terminus was reached before the pans were used.  Did they keep the poles for
a while "just in case" during early pan operation, or could they have
switched to pole when the partially converted right-of-way became
pan-Unfriendly ?

I remember reading about this, and couldn't for the life of me tell you
where (there was, I recall, test track behind the Castle Shannon Municipal
Building involved). Basically, instead of having wire hangers which were
semicircular with the wire up inside (for poles) the cross wires end up
attached directly to the upper left and right of an element which connects
straight across and has a protrusion 90 degrees (straight down) which crimps
around the wire.

So you go out and replace every hanger up the line, and I assume it's usable
by poles as you go. More fun: you should really stagger the wire back and
forth off-center of the track too to avoid wearing a groove in the pan
shoes.

I wish I remembered where the article was.
