Otto, IIRC, you were the only one (or one of maybe two people) who was using the "2-year experiment" reasoning. AFAIK most everyone else who was claiming that the trains would not return were using the ambiguous "low ridership" reasoning. All along, for months now, maybe even going back over a year, I have been asking those people to justify their claims of "low ridership". No one has been able to provide ridership statistics. On top of that, no one has been able to come even close to quantifying what NJT expected the ridership to be. (Many people still, to this day, keep perpetuating the myth that the trains should have been "full".) So without those two pieces of information, it would seem that those people are making baseless claims. Please correct me if I am wrong.
As for your "2-year experiment" reasoning, it very well may be true that it was a 2-year experiment. But since there has been no official statement (AFAIK) that the experiment was a failure, and/or since no one has been able to provide actual and projected ridership numbers, I'm not sure why you thought it was a failure and why that would mean that the 2-year experiment failed and/or wouldn't be continued.
