I used to post here occasionally on the old forums. My grandad rode the DL&W from Summit to Hoboken from the 1920s to the 1960s, while my dad rode Summit to South Orange and Newark for Seton Hall Prep and U. I started making the commute out on the Gladstone Branch to Hoboken in the mid 90s.
The combination of the lengthening of schedules and then the end of the express to Millington were major factors in the deterioration of everday quality of life for me. Most of the ridership didn't know any better, of course, but to be stuck following a MidTOWN Direct train late off the corridor several nights a week was just maddening. Good people certainly worked many of the trains, but institutionally, you could tell the attitude was, "this is the service we offer - take it or leave it." I left it.
Not for the car, however, but for Vermont. The lack of good express service on NJ Transit definitely removed some of the advantage of living further out however, while the utterly unchecked growth in all of NJ removed any vestige of what had been a semi-rural place (towns along the Gladstone nee P&D like everywhere else in the state). And I'm not some transient who didn't understand the place, but someone born in NJ to a family who'd been around the state for a long, long time.
To me, watching a train schedule slip said a lot about the changing motives of the organization, the lack of a focus on measurable standards of excellence, and a general alienation of the constituency of ridership. NJT has focused on the portion of ridership who use the train as transportation of last resort (no knock to them), and has tailored the product accordingly. For me, it was part of an equation that no longer made sense.
