[PRCo] Re: Speers Belle Vernon Bridge tracks? and update to PRyCo Map

[Edward H. Lybarger]

Thanks, Steve.  Now, of course, I'm really curious what that circle started
out as!  There would have been no need for a loop, especially one that size,
for double-end interurban cars.  And the DEM certainly shows a quarry there.

Regrettably, there will always be problems in trying to show all-time
trackage, unless there are detailed text explanations.  Most readers will be
confused, and some will pronounce to the world that something ran there that
didn't.  I guess that's why most mapmakers pick a date or an era for main
tracks, and show the former alignments with broken lines.

Ed, thanks for the comments.
I'll explore different colors for the other Interubans and the boundaries.
Not sure why the railroads seem almost invisible as they show up clearly in
white on the printouts I have made.

Regarding the loop southeast of Valencia. That was based on my original
tracing of the Digital Elevation Model. I looked at the 1938 aerial and
available maps and the loop is not shown so I have removed it. I have
attached the 1938 aerial and DEM in case anyone knows more about the rest of
the "circle" as seen on the DEM.

The right turn on the end of the PRC #12 is based on the 1910 Arnold and
Hopkins 1910 plate 42 showing a trolley line following Evergreen plank road
to right. (Pre Harmony Line). It is also shown as abandoned early on the
PERC Pittsburgh & Vicinity Map. I added it to the latest revision as I
intended the map show all PRyCo routes regardless of when they were
abandoned.

There was no street railway on the first Speers - Belle Vernon bridge, which
I believe was a wooden structure.  (North Belle Vernon is not close to the
river; it is up on the hill.) 

As to the infallibility of railroad valuation maps, I would offer my
standard advice about research..."Question Everything!"

As to the colors on the map...The PRC routes and the interstate highways
show up quite clearly when printed, but it is very hard to distinguish
between the other interurbans and the interstates, and the green city
boundary almost gets lost.  Likewise, the railroads are almost invisible.

And what's that loop-de-loop on the Butler Short Line southeast of Valencia?
The bottom half of that circle didn't exist!

On the Harmony Route at the end of PRC Route 12...HR continued straight
ahead from end of PRC.  PRC didn't make a sudden turn to the right after HR
was abandoned.  HR made that right turn to reach Renfer Viaduct across
Nelson Run.  PRC 12 quit in the street short of the turn.

Happy Turkey Day to all.

Ed
