We’re the official organization bringing a vision for 3 miles of urban greenery, a new kind of park in Philadelphia, to life. We bring community together through nature, free programming, and the arts. Phase One (.25mi) is now open! Our mission is to build bold, transformative, and inclusive public space that connects Philadelphia’s residents and visitors to the city and each other. Through cross sector partnership and community collaboration, the Rail Park will transform a historic railway into three miles of linear park and pathway, enriching the health, culture, and ecology of the city, and creating inclusive economic opportunity for Philadelphians.
