When my grandfather moved to Staten Island in 1930, he commuted to Proctor and Gamble in Port Ivory via trolley from his lovely Port Richmond home.  Has anyone been to Port Richmond lately?  Not lovely, my friends.

I can imagine that some commuters would like a Bayonne/Path connection, but the Bayonne bridge is not a very heavily utilized route, comparatively.

I'm not suggesting that Staten Island, especially the North Shore, couldn't use trains.  My point rather is that it will probably not be a priority there.   The area is relatively poor, and the wealthier parts of Staten Island (which loves the SUV, and maybe NASCAR too) wouldn't really benefit.  IMHO there is little chance that $360 million gets spent there, for that.

I think that if a Bayonne Bridge line is built, the one way that it will really attract a large number of customers is if it is an extension of PATH, turning south at Grove Street, with a stop at Liberty State Park and either replacing the HBLR, or serving as the express line of it, or both, up to the bridge, then over the bridge, with a transfer station for a potential future North Shore Line, and then perhaps continuing south in the median of the highway to Victory Blvd and in the long term forming a cross-island connection via the SI Mall. The key point, though, is the direct connection to Manhattan, with no transfers.
That would be ideal.  Otherwise why go to Bayonne?  Bleh.

My mom would be happy--she could see her grandchildren without the bus/ferry/subway shuffle.
