Early in fall 2012, SEPTA initiated this study to evaluate an extension of the Norristown High Speed Line (NHSL) to the King of Prussia area. The NHSL currently provides service between the 69th Street Transportation Center and Norristown Transportation Center, serving the Main Line area in Delaware and Montgomery Counties, and connecting to Center City Philadelphia. While the transit system is expansive, a rail connection to the King of Prussia area is missing. The King of Prussia Rail Project will evaluate various alternative alignments to make the connection to the NHSL and destinations in King of Prussia. SEPTA invites you to participate in the project development process and provide input.
