A really wonderful photos was posted to the Maryland Division Railfans group on Facebook. The photo was taken in July 1966 at the west end of Georgetown yard, along the Potomac, and is one from a location that I have never seen before; at the end of the passing siding/yard track at the west end of Georgetown. There is a “YARD LIMIT” sign placed at this location that I never new existed. I’m so thankful as it provides a peek at something I never would have known had I not seen the photo. When I model this area on my layout, I will be sure to add that sign! Thanks so much, Guy Span!
