From the December 1927 Church News
Back in 2002, while on medical leave, I attempted to abstract and post online the annual reports of the Philadelphia Department of City Transit. I managed to get the first two years up. Shortly thereafter this map arrived in my PhilaU inbox. A fellow on the Main Line, whose name I have long forgotten, made this for my website. The map is, mostly, based on the original 1913 plan. He added the airport connection “just because.” Anyway, enjoy.
