Septa has commissioned a US$145000 two-year feasibility study into restoring passenger services on the Bethlehem and Stoney Creek lines, providing a commuter service to Philadelphia. Trains would start at Quakertown in Bucks County, and run south through Perkasie, Derstines, Telford, Hatfield and Lansdale before taking the Stoney Creek line on into Philadelphia. The route has not had a passenger service since 1931, but rapid population growth in the area has overwhelmed road capacity.
