How Philly Could Ride a Commuter Train Line Like a Subway
Building new transit infrastructure is expensive, difficult and time consuming, but America’s cities need more of it. Philadelphia especially has a very limited subway-elevated system. (For those unfamiliar, just two lines run along main north-south and east-west corridors.) Philly does have an extensive regional rail system, with three lines that only run in the city limits through dense neighborhoods otherwise only served by bus. But that rail service is infrequent, and prohibitively expensive for many riders.
