I am interested in finding a good source for the actual track layout/siding for Gettysburg PA, circa 1950's. During this period the Western Maryland and the Reading served Gettysburg. I found a really interesting source of the industries present in Gettysburg in 1954 (from the Reading historical site), and now I'd like to see if I can locate how the tracks were actually laid out. Google maps made pretty clear that the last 65 plus years has seen a LOT of change to the town, with the majority (almost all) of the industries long gone and the locations redeveloped pretty extensively - there looks like there is almost no evidence of them today. Is there a good place to find how things were laid out/what industry was where back in the day? Besides model railroading, I enjoy history quite a bit, especially the civil war, so this could be an interesting mix of the two.
