Yes, ThirdRail, I understand what you are saying about boarding the wrong train or , for that matter, the wrong service! Sometimes the Darwin Award has its costs. Its only fair that the winner has to "pay" their prize
In response to both your point and 66's point:
1) They are at least testing it on a small section of the system. The PVL is a growing section of railroad, but still small. Based on the FAQ's, it looks like they thought of quite a bit, but, as both of you pointed out, there will probably be some issues. At this point, I would hope NJT would be sympathetic to the passengers in un-thought of situations, somewhat like the $5 on board surcharge "grace period" when first introducing new TVMs.
2) I also agree that an e-validation system would be better than just having a ticket that expires. The latter is too light rail or bus like. I would think that with a QR code, each ticket would be unique and, once scanned, capable of being cancelled, preventing the same user or multiple users from passing the ticket off more than once - ala the ticket punch. We all do this when we go to an event where we purchased a ticket electronically from TicketMaster. If those e-tickets are bought third hand via E-Bay or StubHub, we probably hope too that multiples were not sold and the one's we purchased still works!
Consider the following situation... The first weekend in early March, the ALP-45s were holding down the M&E and several of us were riding those trains that weekend. What would prevent the auto-expiring ticket from allowing someone to ride in then out again on the same ticket. For instance, the ride to/from Maplewood can easily be done in just about two hours. As long as the ticket has not expired prior to being presented it is still valid. An e-vailidated ticket would be cancelled force the customer to buy a second ticket. (NOTE: I know the M&E is not in the trial, but this is just an example if the system were full deployed).
3) From a revenue collection standpoint, however, a self cancelling ticket insures the RR gets its money. Maybe not all of it (see above), but one way or another it gets it. Once activated, it cannot be used after it expires. This would certainly help in situations like events at the Meadowlands or during special holidays / times when trains are packed and revenue collection can be cumbersome. Also, an auto expiring ticket requires less on-board equipment such as scanners that do not function in cell phone black holes (ala Amtrak and the Baltimore Tunnels).
Not trying to be argumentative with either one of you, but open minded on this one. From a consumer standpoint and RR standpoint this could be a win-win (conveyance and revenue collection), but the system needs, understandably, a good vetting prior to full deployment.
