Philadelphia is an odd duck with regards to light rail.

50,000 of the riders are on the Subway Surface lines (aka Green Lines). These are really five streetcar (trolley) lines that funnel into a downtown subway tunnel that is 2.5 miles long.


I ride the trolley every day to work. It averages 10 mph, and stops on every corner. Even in the subway, it only averages 10 mph because the line was designed with numerous sharp bends and primitive interlockings. But it is much better than the bus.
