The Philadelphia area service is a little more of a hot mess. I don’t believe the Stony Creek branch will only be six minutes more than service through Jenkintown-Wyncote. The branch is a winding mess, always has been always will be. The Manayunk/Norristown also has some nasty curves that you don’t notice because they are just beyond stations. It should, without question, be routed through Jenkintown. Additionally, as has been discussed elsewhere, this extant all diesel routing from Norristown is practically mythical. Yes a southbound connection exists, but northbound requires either miles of “wrong way” operation, or building a flyover in a tight urban area, or reconfiguring a large interlocking system. Such work is exceedingly expensive, and considering it was just redone… It would make sense for SEPTA to operate Doylestown to Center City via Norristown, because the travel time is laughable anyway, and the local connections could be more valuable. Conshohocken is an ugly drive from Doylestown, but a booming job center. The dual mode theory is shortsighted here. SEPTA owns the whole ROW. Doublestack freight is not a problem, save for bits and pieces in the Lehigh Valley. They have to rebuild the entire ROW and signal system anyway, just string the wires and save the time. The people who would use this service are commuters, so service to Market East and Suburban would be more valuable anyway. It should be scheduled with a stop at Lansdale, a stop at Jenkintown-Wyncote, and then lead or follow a West Trenton into town, stoping Fern Rock if necessary and then Temple. SEPTA has slots that can make that work. It should be unreserved, hourly, and clockface, to interface better with SEPTA, and to allow commutable times. In a crazy world, it and the Keystone, could be paid via the SEPTA Key. But this assumes, that people will buy into trails to rails. That is the real challenge to Philadelphia Service.
