Thanks, Bryce for the update. It's understandable why NJ balks, since they would get nothing from a route from PA to NY. That's why the Federal Government needs to be involved. I little thing called interstate transport. They could put a station in Blairstown again, but that is a sprinkling of people. ( I used to live there)
The problem with the stations west of Dover is lack of service as you said. (Not to mention an interminable trip), but I will have to check them out again. Either way, I still have to get in a car and drive a distance to a station, so the extra few miles to Dover is no big deal.
Now if Manhattan implements congestion pricing for mid-town access, that could shake things up.
