Joe, I think NJT would maintain a decent schedule even if some of the places I mentioned were stopped in by the cutoff trains.
If only one or even no cutoff trains would stop in NJ then why should NJT pay for it instead of PennDOT,NJDOT and others who want it bad enough. NJT should pay for projects that affect NJ residents like MOM and W Trenton. I personally wouldn't liek it if a service that mostly serves PA residents is worked on and coems online before projects that serve NJ residents like Mt Arlington Station, electrification of Boonton and NJCL, MOM and W Trenton.
If the cutoff trains made stops in Dover, Morristown, summit, and Newark (yes PA people do work in these towns) before going on to Hoboken then NJT should pay for it since it will also serve NJ towns not to mention western NJ residents living in or around Blairstown and Greendel.
