While connecting the two makes sense in general terms and in an ideal world we would. In world where they are funding priorities and there are many places with inadequate transit, it makes very little sense. To a state legislator or administrator overseeing grant money at the Federal Transit Administration it wouldn't make any sense. I think they would wisely argue, why not, for less money fund improvements to PATH service or improved bus service between the two cities and focus on transit expansion to the areas that are currently lacking? HBLR Northern Branch extension, NLR to Paterson, Hawthorne/Paterson to Hackensack rail, Union County BRT, Bergen County BRT? At the end of the day, there is a glut of need and not a lot of money, why duplicate existing service with something that costs a ton of money, when you can just improve the existing services, and use the money you save to improve transit to areas that are not well served?
