Where will the money come from? NY and NJ are not on a level playing field. Whats in it for NY to pitch in money for these things? Look at Penn Station. NY is spending millions for improvements to Amtrak and LIRR and not a cent for NJ Transit. Or congestion charging, they are about to collect tons of revenue from NJ commuters but not giving a cent to NJ. And what reward does NJ get for investing in cross-hudson transit infrastructure? More commuters living in NJ but giving 100% of their income taxes to NY. It's a big scam.

Remember the Port Authority runs plenty of profitable infrastructure, specifically bridges, airports and ports. Force them to pick up more unprofitable rail service and their business model no longer works. The only reason they run PATH in the first place was as a concession for them to build the World Trade Center.

They are never gonna have the money or political will to meaningfully expand. I think the strategy is to starve it and hope people drive.

Remember there is a giant conflict of interest in all of this, PA runs PATH trains at a huge financial loss, but collects hudson river toll revenue to great gain
