Philadelphia Subway Concourse Map

While walking underneath Center City to stay out of the cold, I discovered that the interconnecting subway concourses are more extensive than I'd first thought. I found a wall map in a corridor connecting the Market-Frankford line with the Broadway line and took some pictures so I could reconstruct the map:

In case you are wondering, the complete graffiti on the wall map says "rode to knowhere."

I've made the map available in PDF format (in case you want to print it) and EPS format (in case you want to edit it):
