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.
