[PRCo] Railroad crossings

[Boris Cefer]

Hello, folks!

I have noted, that PRCo used some protective device mounted closely above
the trolley wire at points where the trolley tracks crossed railroad. Was
e.g. at crossing with PRR Panhandle Div. on Main St. in Carnegy, clearly
visible in PCC From Coast To Coast, page 170. Does anybody know what was
that wire roof for? Seems it could provide an emergency power supply in case
of dewirement to prevent the streetcar stay on railroad track.
