PC: E8 Windows

Gents-

If you look a lot of roads lost their windows, and it looks like mostly PRR
units lost them over NYC units.  The whole panel appears to be replaced
rather than just blanking off of the window itself.

These are General Motors units so the porthole windows may be linked to
Buick portholes, both of which served as just as much of a service to
society as a Pauly Shore movie.
