Suburban Station and Ivy Ridge (Cynwyd Line), and the former Reading's main line between Jefferson Station and Norristown (Manayunk/Norristown Line), before merging on the old Reading Main Line (now Norfolk Southern's Harrisburg Line) west of the current Norristown station. 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. Unlike the RDG trains, the new SVM would be entirely electric, with power being supplied by Amtrak, SEPTA, and (between Norristown and Reading) the Exelon Corporation, the successor company to the former Philadelphia Electric Company, later PECO Energy. Existing catenary wires, powered at 12 kV, 25 Hz AC, would be used on the old lines, with new high-tension catenary poles, powered at 25 kV, 60 Hz AC, and similar to the system utilized on the Northeast Corridor north of New Haven, Connecticut, would be employed west of Norristown. Planners intended to operate trains at 15-minute intervals during peak travel times, Mondays to Fridays, and at 30-minute intervals at all other times. 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. In December 2007, Montgomery County authorized an unsuccessful study that looked at possible new funding sources. Congressman Jim Gerlach announced in April 2011 that the results from that Montgomery County study would be soon published. Greenline Another alternate approach, known as the Greenline, proposed to serve the towns of Oaks and Phoenixville via a new connection at the current Paoli/Thorndale Line at Paoli Station. This project was cancelled when funding could not be obtained. Norristown Extension After the Schuylkill Valley Metro plan was rejected by FTA, the Montgomery County Planning Commission initiated the R6 Extension Study
