Inadequate mapping is a primary reason I have embraced the aerial photos of
Penn Pilot. They have cleared up errors in my own mapping as well as
others'. And nothing beats knowing what you are looking for, a concept that
cannot apply to professional mapmakers...they're too distant and totally
disinterested.

Not so scary as regards PennDOT. Maps don't show everything, and it's
particularly unusual for a highway map to show the course of a railless
railway. Scary, though, for how many decades we were limited to 1:62,500
topo up to half a century out of date.
At first I wondered whether 1976 had perhaps been a major redrawing of the
highway map, but comparison with 1965 puts that to rest. Still, over some of
the country, USGS publication at 1:24,000 hadn't been completed before the
mid-1960s, so is it possible that this information wasn't yet available to
highway department cartographers in 1965? Or maybe it's just that somebody
in 1976 happened across the track of the old railway-that-wasn't and thought
it would be cool to include it.
I have to say, though, that the enthusiasm with which I greeted the highway
maps online was inspired by the depiction of this one railway on the 1976
map. That enthusiasm was severely dampened when I discovered, upon
comparison with the aerial photos, how carelessly PRCo and West Penn were
drawn on the 1940s-era sheets.
