Route A would run to Moorestown, Route B to Kirkwood (now Lindenwold), and Route C to Woodbury Heights. Klauder & Associates recommended using the Bridge Line instead to reach Philadelphia and suggested building Route B first, as it had the highest potential ridership.
The proposed Glassboro–Camden Line would require riders to transfer to the Speedline at the Walter Rand Transportation Center for trips to Philadelphia.The PATCO study also recommended a multimodal, regional initiative to introduce a Camden-Philadelphia BRT, a bus rapid transit system along Routes 42 and 55, as well as upgrading New Jersey Transit's Atlantic City Line to improve its usability.To facilitate their construction, the states of New Jersey and Pennsylvania expanded the powers of the Delaware River Joint Commission, which owned the Ben Franklin Bridge and the New Jersey portion of the Bridge Line, rechristening it as the Delaware River Port Authority (DRPA) in 1951.The agency commissioned Parsons, Brinckerhoff, Hall and Mac Donald (now Parsons Brinckerhoff) to study possible rapid transit services for South Jersey; Parsons, Brinckerhoff's final report recommended building a new tunnel under the Delaware and three lines in New Jersey.PATCO operates 121 67-foot (20.42 m) cars which were acquired in two separate orders, labeled PATCO I and PATCO II.
The original PATCO I cars were designed and manufactured by Budd of Philadelphia in 1968.
In Philadelphia, the line used a tunnel built in 1931 to serve both Ben Franklin Bridge trains and a Broad Street Subway spur designed to serve 8th and Market and the southern part of the city center via Locust Street.
The tunnel, which replaced an earlier proposal for a downtown subway loop, extended under 8th to Locust, then under Locust to 16th, but as tracks were not laid beyond 8th and Market, the first Bridge Line trains did not run beyond 8th Street into the Locust Street Subway until February 10, 1952.
Early in the 20th century, the idea of a fixed Delaware River crossing connecting Camden and Philadelphia gained traction, and in 1919, the states of Pennsylvania and New Jersey formed the Delaware River Bridge Joint Commission to build a bridge between the two cities.
The Delaware River Bridge (now Ben Franklin Bridge) was designed to accommodate rail as well as road traffic; when it opened on July 1, 1926, it had two outboard structures beside the main roadway for rail and space for two streetcar tracks (never installed) on the main road deck.
Cars numbered 101-125 are single units, and cars numbered 201-250 are in permanently coupled married pairs.
