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

[Stephen Titchenal]

I have updated the PRyCo Map after double checking it against the 1910
Arnold map of the PRyCo. I found this map to be fairly accurate after
georeferencing it. I have included a copy of it online with the updated
draft of the PRyCo DEM on my website at:
http://railsandtrails.com/pdf/index.html

Also attached is a section of the PRR Monongahella Main Line valuation
showing Belle Vernon (Speers). It has what appears to be a track on the
bridge between Speers and North Belle Vernon. I cannot find any
documentation of this on any other map. It is unusual for a Railroad
Valuation Map to be incorrect (unlike some other historic maps :-).

FYI: The PRR Valuation maps of the Monongahella Main Line between Charleroi
and Roscoe only show the street railway next to the tracks for a short
distance at the southern end of Charleroi. No tracks show on the West
Monesson (North Charleroi) - Monesson Bridge. I find that the Railroad
Valuation Maps are inconsistent in showing nearby electric railway tracks.
