Does ABE service to Philly 'weigh on equal footing' with service to NYC?
I'd say that the former outweighs the latter by about a factor of twenty to one at this stage. I have heard absolutely no noise about trains going from ABE to NY (or the waterfront in NJ), but plenty about the old Reading line to Quakertown and Bethlehem, which ceased service in the early 80s when the Center City Tunnel opened in Philly and Reading Terminal closed. This was a SEPTA diesel service operated by RDCs in its last incarnation; the line still has the R5 running from as far north as Lansdale. Bethlehem is not being helpful insofar as restarting Philly service; they want to turn the old Reading line (still with tracks) into a "greenway", and they have severed the line from the LV and the CNJ just south of Union Station (which a hospital now occupies). The tracks are in through Hellertown and Quakertown, but are severed in Cooperstown at the grade crossing at the old train station.
Personally, I would have liked to see the CNJ main as an all-passenger line with the LVRR as a parallel all-freight line, but what with building houses on the ROW in Freemansburg and on the CNJ main west of Allentown as well, it would take a massive political upheaval to get things that far. Best we could hope for is having trains use the current freight route, going from LV main to CNJ bridge across the Delaware back onto the LV main and back onto the CNJ main in Bethlehem (which is still in use up as far as the Reading bridge). I-78 and US 22 aren't going to be able to sustain the whole thing for much longer...
