Pennsylvania Rail Road Keystones Survive in Pittsburgh!

After seeing a recent news story about a potential bill to require more intensive and frequent maintenance of railway bridges, I decided that I would want to get Pennsylvania railroad keystones that I know to exist on video before they get sand blasted or painted over. The Keystones in this video are all located in the vicinity of the federal building in downtown pittsburgh in a more precise description is in the video. I hope you enjoyed!
