As someone who lives on the Raritan Valley Line, whose riders have been told the only way we are getting direct one seat rides into NYC is if the Gateway/ARC Tunnel is completed, I have a vested in interest in seeing that project get done. It would benefit everyone's property values not just those who actually rely on NJ Transit to get to work like myself. Having said all that, I did not think what Christie was asking for was unreasonable. The history of delivering such massive public infrastructure projects on time and on budget is poor and it getting it straight upfront as to who would be paying (shouldn't it be the winning bidders?) those overages struck me as exercising the proper due diligence.
The Raritan Valley Line will never have a one seat ride into NYC.
Remember, first and foremost, that whatever project comes to fruition in the form of a new rail tunnel, the very first thing that happens when it opens is that the old one gets closed for about 10 years worth of repairs.
After that, even with four tubes open, there are no plans to have terminal infrastructure in place to allow every train from every NJT line terminate in Manhattan.
