In 2023 the Federal Railroad Administration accepted the route into its Corridor Identification and Development Program, which allocates money for planning and prioritizes the project for future funding.
The City of Philadelphia and suburban counties began providing public funds under contract with the PRR and Reading Company for continuation and improvement of regional rail service.
Commuter service on the former PRR line was extended from Manayunk to Ivy Ridge station in order to serve a new park-and-ride lot.
This operation continued until SEPTA ceased funding for the diesel section in 1981, two years prior to taking direct control of Philadelphia's commuter rail routes from Conrail.
In 1986 service on the former PRR line was cut back from Ivy Ridge to Cynwyd station in Lower Merion Township.
A new spur, called the Cross-County Segment, would split off at Port Kennedy (near Valley Forge), and would allow SVM trains to access King of Prussia, Pennsylvania, and the Great Valley Corporate Center in Malvern, Pennsylvania, using the former PRR/Penn Central Trenton Cutoff (now Norfolk Southern's Dale Secondary) used by the former PRR as a freight-only bypass around Philadelphia, although an alternative would be to have the Cross-County segment serve only King of Prussia with SEPTA extending the existing Norristown High-Speed Line to King of Prussia, via the Trenton Cutoff.
Norfolk Southern Railway trains would have been able to use most of the system at all hours, but would have been restricted to overnight movements at some locations after SVM ceased operations at night between Midnight and 6 a.m.
In August 2006, Pennsylvania Governor Edward Rendell announced that funding for the SVM project would not be forthcoming and that it should be considered dead.
[5] Another approach, known as the Greenline, proposed serving the towns of Oaks and Phoenixville via a new connection at the current Paoli/Thorndale Line at Paoli Station.
Any service west of King of Prussia would require new construction and the purchasing of extra push-pull consists hauled by dual-mode locomotives.
Funding for the R6 Extension Study was to be provided by revenue earned via a proposed plan to toll U.S. Route 422 between Pottstown and King of Prussia.
Stations would be located in Reading, Pottstown, Royersford, Phoenixville, and Norristown; from where the train will follow the existing Manayunk/Norristown Line to Philadelphia.
[23] In May 2022, Berks, Chester, and Montgomery counties formed the Schuylkill River Passenger Rail Authority for the purpose of furthering the project.
