A three-mile section of an abandoned elevated Reading Rail line north of Callowhill Street into a leafy green space with room to walk, sit and admire the Center City view. Phase One, slated to be completed in spring 2018, is an industrial, four-block section. During construction, passersby can learn more about the vision for the park through Friends of the Rail Park board member-led, street-level walking tours along the site.
