The public transportation landscape of the Philadelphia metropolitan area is intricately woven together by two major entities—the Southeastern Pennsylvania Transportation Authority (SEPTA) and the Port Authority Transit Corporation (PATCO). The line opened between Lindenwold and Camden on January 4, 1969, with the full line to Philadelphia opening a few weeks later on February 15, 1969. Its diverse services include buses, trolleys, regional rail, and rapid transit lines such as the Market-Frankford Line and the Broad Street Line, which seamlessly connect Philadelphia and its surrounding areas. On the other side of the Delaware River, the Port Authority Transit Corporation (PATCO) Speedline began operation on February 15, 1969, fostering a vital link between Philadelphia and Camden County, New Jersey. This rapid transit system has expanded over the years, particularly as it expanded its reach to Philadelphia International Airport in 1985. Together, SEPTA and PATCO play an integral role in shaping the mobility, connectivity and accessibility of Philadelphia's vibrant and historic city.
